Another article on one of the greatest mountain runners of all time on RockyMountainNews.com. Here is one great tip from Matt:
Take it steady when it comes to the mountains
You’ve just got to focus on your cadence. I think a lot of people really try to grind it up hills. Let the terrain dictate your pace, but if you can keep the same cadence overall, it should take care of itself. If the terrain gets too steep, by all means, walk. The key is, don’t go into it with a hardheaded attitude. Even I have races where I have to walk. If you can just relax and do it, that’s OK. You’re going to do a lot better than the guy next you who’s fighting and trying to run when walking would be better.
