Colorado Springs, CO

Colorado Springs is defined by elevation and proximity to Pikes Peak—the city sits at 1,830m with the 4,301m summit 25km west, making it a testing ground for high-altitude running and mountain cycling. The Pikes Peak APEX Mountain Bike Marathon and Pikes Peak APEX Gravel Race both anchor the local scene, drawing riders who train on the surrounding Front Range climbs and the network of singletrack in the Wissahickon area. Runners gravitate to the flat Arkansas River Trail for aerobic work, then head upslope into the foothills and the Manitou Incline for serious elevation gain and altitude adaptation.
