A true test of mental and physical strength, the adidas Terrex Pepi’s Face-Off is a “beautiful pain” as racers navigate up AND down the black-diamond trail Pepi’s Face as many times as they can in 30 minutes. Named after Vail legend Pepi Gramshammer, Pepi’s Face features about 250 vertical feet with a near-45-degree pitch — one of the steepest runs on Vail Mountain. What was once an intimidating race is now one of the most popular at the GoPro Mountain Games — both for athletes and spectators.
