the climb

Climbs are graded by difficulty, the harder the climb you can do, the more respect you get. The (US) grades go from around 5.5 to 5.15, higher numbers mean harder routes. There are a few almost-cutting-edge difficulty routes on youtube. I'd reccommend this of Iker Pou on Action Directe, and this of a crazily long and overhanging route somewhere. Both around the 5.14 mark.
That second climb is insane.
