|Downhill trail running at Crater Lake|
I love my downhills. Unlike many runners at mountain or trail races, this is the bit that makes it really fun for me and some of the most enjoyable solo moments in running are technical downhills where there's the chance to bounce around on rocks. If you see me at a race on a downhill you may see a lunatic grin on my face which I just can't help when it gets really fun. Uphills just aren't fun in the same way for me personally and are just a suffer-fest.
As a coach one of the most frequent questions I get is tips for running downhill better - more efficiently and in a way that causes less damage to the leg muscles. So this video from Portland-based Dana Katz includes helpful commentary and explanation of things to look for and aim for when downhilling. It was taken at the 2013 Miwok race last weekend and is of me running around 11 miles into the race.
Also, here's her full article showing both good and bad technique.
