Want nothing to do with ridge lines or ledges like that... did one at the Col du Cou near Morzine which even in 8-year hindsight was type-3 fun. Riding on a narrow footpath where one side was a trip to hospital and the other the cemetery; not my idea of fun at all.
More from the same dude... I'll just manual along this cliff at 60kph...
