Each year the USA Pro Challenge searches for ways to include more of Colorado’s deep cycling history. Last year it was the climb up Bachelor Gulch and this time around it will be the unpredictable Kebler Pass. Stage 2 opens fast by ripping down the Aspen Valley through the sprint cities of Basalt and Carbondale before tackling the 8,700 ft. McClure Pass. A short descent brings the race to Gunnison County road 12, which is a 20-mile rollercoaster that constantly changes from pavement to dirt and back again, while topping out at 9,900 ft. over Kebler Pass. A technical descent into Crested Butte brings the race back to familiar terrain. As in 2011 and 2012, the race will finish up with a sprint through downtown Crested Butte and the steep finish climb up to Mt. Crested Butte.
