Top 10 Female Ultra Performances of All Time

Given there are plenty of annual lists at this time of year for best performances and runners, it got me thinking about the very best ultra performances of all time. Obviously it's impossible to have some perfect formula to compare every aspect of one performance to another, but I used my own experience from road, track and trail racing (as well as coaching elite women) to consider the most impressive female runs ever and have included the equivalent list for men here.

I factor in the level of competition on the day, the level of competition that's attempted the world or course record at any point in history, weather (where applicable, like at Western States where it can vary significantly) and knowledge of the tactics and skill used to get such a great performance. I was lucky enough to see some of these performances in person or at least meet most of the runners mentioned below.

I include only one performance per race, unless the race has more than one format or direction (like Comrades with its Up and Down runs or the clockwise/anti-clockwise directions at Hardrock 100).  Also, how well these records stand the test of time is important, so a very well-challenged record from longer ago is deemed to be especially impressive.

I also work off the assumption that if a runner hasn't been caught doping then their results are legitimate, since unfounded accusations are spiteful. Anyone who is a confirmed doper is not part of this list (that I'm aware of).

1. Tomoe Abe, Japan - 100k World Record at Lake Saroma, Japan (6:33:11, 2000)


She set the fastest 100k time for women by a long margin (nobody else has broken 7hrs and Ann Trason is one of the closest with a 7:00:47 best). I've heard that this record was set with a tailwind, but it's still so far ahead of any of the other road or track marks set by women at any ultra distance that it really stands out. To give an idea of Abe's caliber, she won the bronze medal in the marathon at the 1993 World Championships and her personal best time is 2:26:09. In addition, she ran a 2:28:01 in the same year as her 100k record and a 2:27:01 the following year so was very much at her peak at that point. This is equivalent to 5:16 for 50 miles (compared to the 5:40 world record by Ann Trason), or even quicker if she slowed towards the end of the 100k. Also, this record is surprisingly close to the men's record by Don Ritchie of 6:10:20 (number five on the top 10 all time ultra men's list).

2. Frith van der Merwe, South Africa - Comrades Down Run Course Record (5:54:43, 1989)

van der Merwe destroyed the Comrades down run record in 1989 and nobody's come very close since, with just two other women breaking 6hrs - Ann Trason with a 5:58:24 in 1997 and Tatyana Zhirkova with 5:58:50 in 2005. van der Merwe's average pace was 6:23/mile, working out as around 5:19:30 through 50 miles with hills. The down run is usually won in a time around 6:10:00 and the record looks safe for the moment.

However, the up run course record of 6:09:24 (Elena Nurgalieva, 2006) isn't quite as comparably fast and doesn't make the top 10 list. It's 15 mins off the down run record while the men's up run record is only four minutes slower than the down run record (see the top 10 all time ultra men's list).

3. Rory Bosio, USA - UTMB Course Record (22:37:26, 2013)

The top ranked trail performance is by Rory Bosio, who decimated the Ultra-Trail du Mont Blanc field two years in a row (2013 and 2014 wins), taking over two hours off the course record and finishing seventh overall in 22:37:26, well ahead of the female competition. On top of that she made it look easy, smiling and playing in the mountains throughout the race. This is arguably the most competitive trail ultra in the world and Rory was so dominant that this could easily have been number one in the list.

4. Ann Trason, USA - Grand Slam of Ultra Running Record (79:23:21, 1998)

No woman dominated ultra running like Ann Trason. 14 wins at Western States 100, including the former course record, plus wins at Comrades, the 100k World Cup and just about every major ultra you can think of in the 1990s. She also holds American and World Records at numerous distances, most of which still stand today. She generally raced the men since no women could keep up with her and the fact she has several spots in this top 10 reflects that her times are just as competitive today.

However, I judge the top-rated performance of her career as her Grand Slam of Ultra Running record, the combined time for the Western States 100, Vermont Trail 100, Leadville Trail 100 and Wasatch Front 100, all over one summer in a period of 10-11 weeks. The next best female time was nine hours back by Krissy Moehl! Ann was the female winner in each of those races, which wasn't unexpected for such a talented runner, but it speaks to her ability to not just perform well for a single target race but to manage so many other factors within ultra running to stay strong and fast through each of these races. If there was an award for the best female ultra runner of all time, it would be hard to argue against Ann as the clear winner, especially with her breadth of dominance.

5. Anna Frost, New Zealand - Transvulcania Course Record (8:10:41, 2014)

Anna's had numerous spectacular performances and is undoubtedly one of the best female mountain runners of all time. Her course record at the hyper competitive Transvulcania ultra on the island of La Palma in the Canary Islands is something that stands out. When Anna's on top form she's like a steam train uphill and most of the very fastest mountain women of the modern era have tackled this course and not come close to this time. Only Anna herself (8:11:31 in 2012) and Skyrunning star, Emelie Forsberg (8:13:22 in 2013), have come close to this performance.

6. Ellie Greenwood, Great Britain/Canada - Western States 100 Course Record (16:47:19, 2012)

When someone breaks the record by a large margin at the oldest 100-mile trail race in the world and the former record was the result of 14 wins by Ann Trason, you know it's a special performance. Yes, the weather was very mild and that made it quicker, but it was 50 mins faster than Ann's best. It may take another colder year and a group of the quickest women ever in the world to break this record. Several of the other women in this list have tried, many on more than one occasion, but Ann and Ellie are the only women to break 18hrs.

7. Nicole Studer, USA - Rocky Raccoon 100 Record and Trail World Best (14:22:18, 2015)

The 100 mile record for trails has been less tested by the quickest women in history, but is still a very solid mark. Nicole took 35 mins off the course record at Rocky Raccoon 100 in a mind-blowing performance and took 20 mins off the existing world trail best from Tunnel Hill 100, a flatter course that's arguably easier. Nicole started fast and held on for an astounding win that doubled as the USATF National Championship and not far off the 100 mile record for any type of terrain, which stands at 13:47:41 by (you guessed it) Ann Trason, dating back to 1991.

8. Ann Trason, USA - Leadville Trail 100 Record (18:06:24, 1994)

Ann's Western States wins were clearly excellent, as were many of her road and track records, but her 1994 winning time at Leadville is far ahead of any other woman at that race. The high altitude course sits between 9,200ft and 12,600ft, with around 15,000ft of vertical gain and the same descent. It includes a lot of fast, flat running but that altitude slows it significantly and many fast women have raced it, with only a handful breaking 20hrs.

Stick with me for a minute here for some back of the cigarette packet calculations...Using my own rough comparison of the Western States 100 and Leadville Trail 100 courses (from running both numerous times) I'd estimate that the male course record times (14:46 for WS100 and 15:42 for LT100) are roughly equivalent in terms of difficulty, giving the nod to Matt Carpenter's LT100 as being marginally more impressive. So I think of them as having a one hour difference for that pace, meaning around 1:10 at Ann's pace, i.e. her 18:06 at LT100 is equivalent to a sub 17hr WS100. So, pretty damned quick, then.

9. Ann Trason, USA - American River 50 Record (6:09:08, 1993)

You could pick any number of Ann's records as being amongst the best runs in the world, but the only other one I choose for the top 10 is her American River 50 record from 1993 - a race that's been competitive since it's inception in 1980. That older course was quicker than the current course and involved about 50% bike path and 50% rolling trail, but this is a record that's been tested over the years, not least by Ann herself within her five wins. The only other woman under 6:30 is Ellie Greenwood, who's career mimics many of the elements and highlights of Ann's.

10. Anna Frost, New Zealand - The North Face Endurance Challenge 50 San Francisco Record (6:56:07, 2011)

Anna's second appearance in the top 10 is at the season-ending TNFEC50 in the Marin Headlands. The large prize purse and reputation of the race means it's always got a deep field and the aggressive running for the men's record by Zach Miller from 2015 was also spectacular, narrowly missing out on inclusion in the men's top 10. It's often muddy and the rolling hills add up to around 10,000ft of vertical gain, so sub-7hrs is extremely fast and involves beating the quickest women in the world on runnable, hilly trails. In comparison, the similarly difficult Lake Sonoma 50, which also attracts a stellar field and has 10,000ft of vert, has a female course record of 7:08:23 by Steph Howe, which narrowly missed a place in this top 10.

Top 10 Male Ultra Performances of All Time

Given there are plenty of annual lists at this time of year for best performances and runners, it got me thinking about the very best ultra performances of all time. Obviously it's impossible to have some perfect formula to compare every aspect of one performance to another, but I used my own experience from road, track and trail racing to consider the most impressive male runs ever and have done the same for female performances here.

I factor in the level of competition on the day, the level of competition that's attempted the world or course record at any point in history, weather (where applicable, like at Western States where it can vary significantly) and knowledge of the tactics and skill used to get such a great performance. I was lucky enough to see some of these performances in person or at least meet most of the runners mentioned below.

I include only one performance per race, unless the race has more than one format or direction (like Comrades with its Up and Down runs or the clockwise/anti-clockwise directions at Hardrock 100). Otherwise, many of the best performances would be at Comrades due to the depth of the field at the world's largest ultra both currently and for almost 100 years in the past and it would dominate the list. Also, how well these records stand the test of time is important, so a very well-challenged record (not all have faced much competition) from longer ago is deemed to be especially impressive.

I also work off the assumption that if a runner hasn't been caught doping then their results are legitimate, since unfounded accusations are spiteful. Anyone who is a confirmed doper is not part of this list (that I'm aware of, despite allegations against some of the runners below).

Numbers 1 and 2 are Leonid Shvetsov. Photo: Comrades Marathon

1. Leonid Shvetsov, Russia - Comrades Up Run Course Record 87kms (5:24:47, 2008)

Shvetsov has a marathon best of 2:09:16 from 1997 and is a two-time Olympic Marathoner for Russia. His Comrades wins in South Africa were back-to-back and I rate his up run record from Durban to Pietermaritzburg as the better of the two, especially since very few runners can win both directions. Despite it being marginally shorter than the down run (54 miles compared to 55.5 miles), it has around 6,000ft of ascent and 4,000ft of descent and is usually much slower than the down run. The women's records are 15 minutes apart compared to just four minutes difference for the men. This race has up to 20,000 runners and just getting in the top 10 in the up run requires a 50-mile split around 5:20 with all that uphill.


2. Leonid Shvetsov, Russia - Comrades Down Run Course Record 89kms (5:20:41, 2007)

The down run at Comrades is quicker with around 4,000ft of ascent and 6,000ft of descent and this course record required an average pace of 5:46/mile or 2:31 marathon pace for more than two marathons...with hills. This record had inched down over the years and Bruce Fordyce deserves a mention here for his nine wins at Comrades and for holding the record at both the up and the down - Shvetsov broke his 5:24:07 record from 1986! The back end of the top 10 at the down run requires running around 2:40-2:45 marathon pace for this distance, with hills, something that's just plain astounding in terms of the depth of the field.

3. Yiannis Kouros, Greece - 24hr World Record at a track in Adelaide, Australia (188.63 miles, 1997)

Kouros is the Lionel Messi of running with a list of world and age group world records that goes on forever. He focuses on roads and track running and dominated even into his 50s. However, many of the areas he got records in are not tested by as deep a field of runners as the other performances in this list and his stand out performance is his 24hr world record, the race format where the top 11 times ever are all by Kouros and barely anyone can even reach 90% of his mark. He also has the record for the Spartathlon race in Greece, which nobody has come close to, but this top 10 list is based on the factors mentioned at the top of the page, and even that record is not as impressive as his 24hr record. If this was a top 100 ranking, Kouros would make up a lot of the places. However, trails weren't to is liking, as shown by his sole Western States 100 run in 1988 where he was 24th overall in 20:12:54.

4. Matt Carpenter, USA - Leadville Trail 100 (15:42:59, 2005)

Of all the trail records, I think this one stands out as the most impressive. Despite minor changes to the course over time, nobody has come close to Carpenter's 2005 time, where he had a level of dedication and scientific focus that I've rarely seen or heard about in any sport. The Colorado course varies between 9,200ft and 12,600ft and that altitude slows most runners considerably, but Carpenter has an ability to run at altitude that may be the best ever seen within racing globally. Over the years a lot of top level ultra runners have tested his record but none have even broken 16hrs. To back up his credentials, his seemingly untouchable Pike's Peak Marathon record is testament to this too, another record that nobody has come close to.

5. Don Ritchie, Great Britain - 100k World Record at a track in London, UK (6:10:20, 1978)

Don holds numerous records, including the British 100 mile record (11:30:51 in 1977), which was the world record when he ran it. He's the only person to break 6 minute/miling in the 100k and his record is older than I am (just).

6. Kilian Jornet, Spain - Hardrock 100 Clockwise Course Record (22:41:00, 2014)

Kilian's won nearly everything, set records everywhere and is the only real global megastar in the sport ever. However, many of his most impressive performances are at sub-ultra distances and I suspect he rarely goes to 100% effort in ultras, especially given how frequently he races and how easy he looks even at finish lines. Again, he'd probably have a lot of entries in the top 100 performances, but his astounding Hardrock 100 clockwise record in Colorado's San Juans shattered the previous best and led to another win and anti-clockwise record the following year. Most amazingly is that he didn't seem to go all-out for this record and could probably go a fair bit faster. Nobody is able to touch this performance this race even through the extremely tough lottery has yielded some of the best mountain 100-milers to have a try.

7. Rob Krar, USA - Western States 100 (14:48:59, 2015)

Rob is probably the best ultra runner currently competing at a high level not named Kilian and those two have only raced once, with Rob taking the win at the 2013 UROC 100k to Kilian's 4th. When he's in race mode he could probably run through a brick wall without noticing and this level of focus and toughness got him wins at California's Western States 100 in 2014 and 2015. He's the only man to break 15hrs twice and narrowly missed the course record by two minutes, despite temperatures around 30 degrees Fahrenheit hotter than the record-setting year of 2012 (by Timmy Olson). His tactics were perfectly executed on the day for one of the finest ultra races ever.

8. Xavier Thévenard, France - UTMB Course Record For New Longer Course 170kms (21:09:15, 2015)

Even though the UTMB course around Mt Blanc has been getting slightly longer over the last few years and the level of competition is arguably the highest at any trail ultra globally, Thévenard repeated his previous victory and decimated the field with a tactically perfect race with a 48-minute margin of victory at the finish.


No photo available - anyone got a picture of Magawana?

9. Thompson Magawana, South Africa - Two Oceans Course Record 56kms and 50k World Record (3:03:44, 1988, with the 50k WR set as a split at 2:43:38)

Raced in Cape Town in South Africa, this is another long-standing record and included the 50k world record as well, even more impressive since the 50k mark is at the top of the largest climb in the race before a fast 6k to the finish. This record includes 2:18 marathon pace for an extra third of a marathon, with two significant hills, plus the 50k record is at 2:17 pace, suggesting that Magawama had to hammer that hill to break from his competitors then held on for the win in the easier final kms. The combination of speed and competitiveness in this event makes it the fastest ultra in the world, as well as the second biggest after Comrades.

10. Alastair J Wood, Great Britain - London to Brighton Course Record 54 miles (5:11:00, 1972)

The 'other AJW' was a Scot and a 2:13 marathoner who held the European Record for the marathon. London to Brighton was started in 1952 through the inspiration of Comrades champion, Arthur Newton, who moved to the UK from South Africa and wanted to recreate his home country's banner race with a similar distance, hilly, point-to-point course. Several winning times were very close to the 1972 record, including Bruce Fordyce in the third of his three wins in 1983 (5:12:32, which includes the official 50-mile road world record of 4:50:21). However, Wood's win suggests a split of 4:48 for 50 miles, which is around the same split as for Leonid Shvetsov in his Comrades down run record. This race was the first ultra I ever ran and it was also the final running of this classic event (2005), so it holds a special place in my heart and if you've never heard of it, have a read about it's insanely fast history here.

Across The Years 72/48/24hr

Motivational signs - always useful. Translation from American to British English:  If you are literate then you're a jolly spiffing chap.

After the Desert Solstice 100 mile/24hr race was cut short at 70 miles by my inability to accept that Phoenix, AZ, can be stormy, windy and cold, I was looking forward to down time at the end of the season. However, the Coury brothers also have a second 24hr-style event called Across The Years so I decided on Christmas Eve that I didn't want my training to go to waste and I entered it.

It's an interesting concept - 72/48/24hr races that straddled 2012 and 2013, hence the name. And instead of a 400m track like at Desert Solstice, it uses a flat 1.05-mile loop near Phoenix on a gravelly path with some paved sections. That sounded more interesting, plus it has a lot more people than the 20 runners round the track.

In fact, at least five of the runners returned after varying degrees of success at Desert Solstice - Joe Fejes won the 24hr race 2 weeks ago and smashed Yiannis Kouros' old 72hr course record this time with 329 miles (six more than Yiannis); Charlotte Vasarhelyi won the 24hr race before then broke the Canadian 72hr record with almost 251 miles and I returned with Mike Arnstein (12:57 in the 100 with a ridiculously fast final three hours followed by 100 miles this time in the 24), Dave James (about 23 miles at Desert Solstice then 50 miles on day one and 50 more on day three of ATY). Full preliminary results are here.

I turned up a day early to spectate and crew for Bret Sarnquist as he did the 24 over the middle day of the event since there were three separate 24hr races with the winner being whoever ran the most out of all three days. Compared to a trail race there were a lot more marathon T-shirts, especially from Boston. But as with any ultra everyone was as friendly as can be and it was good to make new friends. Plus my old running club in London had a representative in the 72hr event in my friend, Jen Bradley. She jumped in at the deep end of ultras this year by running her first 100 (I think) then running across the US over the summer. Then she had a really solid race at ATY with over 200 miles and third woman. I can't fathom doing that loop for three straight days...

Jen Bradley and Anastasia Supergirl Rolek in the 72hr race

Running 70 miles at a pace that was on track to go under the American Record for 100 miles two weeks ago left me more tired than I realized so within an hour or so my legs were sore, even at 30 secs/mile slower than the pace in that previous effort. Not a good sign, but this time I was in for the full 24hrs so it looked like being a long day with a 3:18 marathon split feeling more like a 2:40 effort. Mike Arnstein found the same and Dave James wasn't feeling it either, so we all hit 50 miles between about 7:20 and 7:40, way off the pace I'd hoped for. Dave stopped, but Mike and I grumbled along, epitomized by us both frequently mentioning we couldn't see the point of running/walking a relatively poor distance. We also definitely questioned why the hell we do this sport when the tough days can be so unnecessarily nasty.

It was a beautiful, warm and sunny day and the aid station had a full kitchen where they took orders for meals and had a wide variety available. It's certainly a great set-up, but the gravel paths were tougher on the feet than expected. Most runners were in road shoes or racing flats, but those who switched to trail shoes seemed to avoid some of the (unexpected) foot bruising that 24-72hrs of running on that surface caused.

Things weren't going to plan but we'd made the effort to fly out, me from Oregon, Mike from New York. Dave had only driven up the road from the same metropolis as the race was held in, so he probably had less incentive to keep going. However, once I told Mike that there's a buckle for breaking 100 miles, he put his head down and we set about checking off slow miles, with me doing little else but walk after the first five hours. However, there was a bright spot when I decided to reinvigorate my legs by trying a fast lap and aiming to go under Sean Meissner's best lap time from the previous day of 6:09 (5:51/mile pace). I squeezed out a painful 5:41 (5:24/mile) then went back to walking as it didn't do anything other than brighten up my outlook for half an hour. 

Sean Meissner leading the way on the 24hr race on the middle day.

Tents - where people hid in the middle of the night to reduce the number of people out there from about 170 to more like 20. Bastards!

The one thing I'm happy about is that I chose to grind out a full 24hrs even though there was no hope of getting anywhere near my goal of the 24hr British record of 170 miles. Given I've got the Grand Slam (four 100s over the summer) in 2013, I thought it was worth sucking it up and proving to myself that I can force out a semi-respectable result even when things go bad. But this was the most miserable and painful race of my life, as well as the longest in terms of time and distance. I've never had to dig really deep in an ultra before about half way so this was an emotional experience with a lot of time walking through the sub-freezing night to contemplate about many things and to work out how to avoid this happening to me again.

In the end Mike stopped at 100 miles after about 17hrs while I went through 100 in just over 20hrs after hitting 70 at 12hrs and managed 109 in total (a mere 39 from the second 12hrs), with around 65 of that as a power-walk. Not fun, but satisfying to have not given up, despite the final 19hrs (longer than I've ever run) being a painful, slow and difficult death march. 

Without a doubt it was a fun idea to bring in the New Year while doing something that I love, but I was in a world of misery at that point and was struggling to get my head around the idea of there still being nine hours left, even as we toasted with champagne at the aid station. But there are much worse ways to celebrate the New Year, although I'd have struggled to name them at the time.

The other positive to take away (apart from proving to myself I can dig in even on a bad day) was that I somehow won since nobody else did more than 106 miles and many who could have gone farther stopped at 100. I don't blame them. But that's overshadowed by the fact that several of the 72hr runners did more miles on day one (and maybe day two) than me - Joe ran around 140 miles on his first day!

So, lessons have been learnt. Firstly, fixed time races are mentally tougher than fixed distance trail races and very boring once things go wrong. Secondly, 70 miles at a reasonably hard effort tires me out more than I can tell from one test run. Thirdly, I should end my season when I originally plan to and not add on extra races, especially very tough ones. And finally, the Coury brothers put on excellent races via Aravaipa Running and I should probably turn up to one giving it more respect than just assuming it's relatively easy because it's flat.

Time for the off season, trips to Bend's brew-pubs plus a lot of sleep. Happy New Year everyone!

Additional write-up:

I wrote the above while on the plane out of Phoenix. However, I then got stuck at Portland airport overnight after no sleep for two days. It wasn't just a delayed flight but a flight that started at PDX, flew for 25 mins to Bend, circled for 40 mins then decided the freezing fog was too dangerous and we went back to PDX to arrive after 11pm. Since it was a weather delay Alaska Airlines wouldn't pay for anything and I ended up 'sleeping' in the airport. I got home by 2pm on Jan 2nd and am now looking forward to a year that can only improve and with a lot of fun stuff lined up.

Top Global Ultra Performances in 2012

This year has been spectacular for ultrarunning. Given we're near the end of 2012 and there aren't many chances for mind-blowing performances left before 2013 (probably none on trails), I thought I'd go through some of the incredible runs that people have done this year. I've been lucky enough to see many of these in person and each has been inspiring and helped to push the boundaries of our sport. There were many more great runs than those below, but these are the ones that really stood out to me as being on a different level.

Men:

Dakota Jones, Transvulcania, Canary Islands (Spain), May - With almost 15,000ft of ascent in somewhere around 50 miles in this Skyrunning Ultra, plus heat, humidity and a large portion of the world's best mountain runners, Dakota ran a 6:58 course record. Having run the course up and around a stunning volcano personally, his dominating performance was really special and set the bar early in the season.

Ludwick Mamabolo, Comrades, South Africa, June - Arguably always the deepest field of ultrarunners in the world, it takes sub 6 min/mile pace over 55.5 hilly miles to win this in a 'down run' year. The top 10 men were spaced out by a mere nine minutes and the winner has to be considered to be one of the most impressive ultrarunners globally. Sadly, this year was marred by the fact that Mamabolo seemingly failed his A and B sample drug tests according to all the newspaper articles I could find. Strangely he's not been disqualified and there doesn't seem to be any news on this since July (when his B sample was tested and failed).

Tim Olson, Western States 100, USA, June - Admittedly the weather was favorably mild but Tim destroyed the full course and the record with his 14:47 finish (20 minutes off Geoff Roes' 2010 North American Ultra Performance of the Year). His pace over the last 38 miles distanced him from the pack who were all around course record pace (and annoyingly just a few minutes ahead of me) for the fastest finishing split ever. This is a record that I suspect will last at least until the next time the weather is freakishly easy and that could be a long time. I'm not sure anyone could come close to that time in the heat.

Mike Morton, Badwater 135, USA, July - Mike's run was a minute off the course record of 22:51 for 135 miles through Death Valley in obscene temperatures. I only saw him once while I crewed Aussie Dave Eadie since he zoomed off at such a pace it seemed impossible to sustain. He was under the course record splits until very close to the end but a slow climb up towards Mt Whitney robbed him of the record. It was the first time I witnessed Mike's running and his style and pace makes it such a great thing for the sport that he's back to full fitness and racing again.

Hal Koerner, Hard Rock 100, USA, July - Hal's proved he's a tough runner on any type of terrain but is better known for his fast times at relatively flatter 100-milers, like his wins at Western States, Rocky Raccoon and Javelina show. But he ran 24:50 for one of the fastest times ever at this insanely hard and high altitude race. Not bad for someone not living at altitude and firmly placing him among the top ultrarunners of the year.

Kilian Jornet, Skyrunning and Other Ultras, Globally, All Through Summer - I don't even know which of his runs was most impressive but he showed again that i the mountains he's second to none with wins at Speedgoat 50k (controversial and technically a DNF), Trofeo Kima, Cavalls del Vent and Grand Raid de la Reunion. He also won numerous non-ultra mountain races, often beating the best runners in the world, including Max King (see below for what he does out of the mountains).

Mike Morton, World Championship 24-hour race, Poland, September - Mike won the gold medal with one of the best 24-hour results of recent years and smashed the US record too with over 172 miles. That's an AVERAGE pace of 8:20/mile for a full day! Amazing as this is, it's still 16 miles short of Yiannis Kouros' mind-bending 188.6 miles, the world record from 1997. That's probably Yiannis' most amazing record (just my opinion there) and that's saying something from such a legend, so Mike's distance is still absolutely incredible.

Max King, UROC 100k, USA, September - After a couple of 50-milers that saw Max blow up near the end, he focused more on long runs and it paid off with 7:57 for at least 60 miles and something like 10,000ft of ascent. Running behind I was convinced he'd blow up (or more likely get lost given he has a tendency to do this while leading) but he sustained the pace and broke away from speedy marathoner and US Mountain Running Team member, Sage Canaday. Yes, there was a lot of road in this one, but not much was flat and this was probably the most impressive performance I saw this year.

Max King, JFK 50, USA, September - Last year David Riddle's 5:40 course record got the North American Performance of the Year so Max's 5:34 shows another level of pace and was yet more proof of his incredible abilities in ultras.

Miguel Heras, TNFEC San Francisco, USA, December - Probably the deepest field of the year at an ultra, although a few top contenders certainly weren't there (Max King, Geoff Roes, Anton Krupicka, Kilian Jornet and others) but there's no way that everyone will manage to turn up uninjured and pick the same race since that doesn't even happen at the Olympics. Miguel ran incredibly fast and benefited from the leaders going off course then having to catch up later. However, his closing lap was so much better than everyone else that there's a good chance he'd have caught and overtaken the leaders anyway. 5:33 for almost 47 miles of muddy hills was truly exceptional.

Women:

Anna Frost, Transvulcania, Canary Islands (Spain), May - Like Dakota's run at this race was his most impressive of the year, this was Anna's most amazing run. 8:11 smashed the course record but nobody else even got close to her and she was mainly racing to get into the top 10 men in a deep field of talent, just missing out with 11th.

Elena Nurgalieva, Comrades, South Africa, June - The Nurgalieva twins have dominated both major South African road ultras (the other being Two Oceans) for a decade but since Olesya was having a baby there was no chance of another 1-2 finish. Even when they had a bad year in 2011 and struggled, they still managed to finish in the top two spots. Elena racked up her seventh win (third in a row) and tenth consecutive podium with her fastest ever time - 6:07 (6:36/mile) for 43rd overall!

Ellie Greenwood, Comrades/Western States 100 double, South Africa and USA, June - Ellie chased Elena down at Comrades and finished a mere minute off the win (48th overall), which is impressive enough in itself. Then three weeks later she took a whopping 50 minutes off Ann Trason's rock solid course record at Western States 100, running 16:47. These are probably the two best performances of the year by a North American (yes she comes from Scotland but is virtually a Canadian citizen now). Admittedly there's the same asterisk by the Western States time that Timmy has for his CR, but I have no doubt that both of them ran the best performances ever by a woman and man, respectively, at Western States.

Lizzy Hawker, Spartathlon 153, Greece, September - After a month in which she won the shortened UTMB and Run Rabbit Run 100, she also won the Spartathlon 153-mile road race with a course record 27:02 for third overall. Lizzy's always pushing boundaries, but that month was something special and the Spartathlon win on what must have been tired legs was impressive.

Ellie Greenwood, JFK 50, USA, November - obviously 2012 was kind of Ellie's year given her results at trail, mountain and road ultras of multiple distances. But the other really notable performance was her 17 minutes off the course record of America's biggest and oldest ultra. Her win and record was no surprise but cemented just what a versatile and fast runner she is, running 6:12 for tenth overall.

So I think it's fair to say that 2012 showed a step change in the level of trail ultrarunning with so many course records being broken, often by large margins. For example, we saw the eight of the top 20 Western States times for the men in the 2012 race, plus six of the top 20 women's times. Many major races required times that would normally win just to get anywhere close to the podium. So 2013 is something to look forward to.
