Freeride mountain biking isn’t for the faint of heart — even watching athletes plunge bike and body over steep, treacherous terrain will leave your pulse racing.

A group of the most elite freeriders get together each year at Redbull Rampage where they race downhill over some of the most treacherous terrain in the country: the rocky cliffs of Virgin, Utah. What makes this race even crazier–besides the challenging terrain–is that riders must forge their own path. Each contestant has eight days to chip and dig a make-shift trail that will hopefully lead them to the finish line in one piece.
