I don't know which is more insane. The Wilder Kaiser descent we published the other day or Danny Macaskill on his native Skye tacking the Cuillin ridgeline on his mountain bike.
Ok he climbs Sgùrr Dearg with his bike on his back and he doesn't ride back down but lets not be mean. Plenty of Mad skillz with bunny hops, front flips over sheep fences and very airy ridges. Great use of the drone there too.
