Century Rides in Colorado
The comprehensive 2026 directory of 100-mile centuries, metric centuries (62 miles), and endurance cycling tours across Colorado.
Cycling in Colorado: Terrain & Route Overview
For climbers and endurance purists, Colorado represents the pinnacle of North American century cycling. Here, 100-mile courses are defined by thin mountain air, long switchbacked mountain passes ascending above the tree line, and sweeping 40-mile descents down roaring river canyons. Iconic centuries such as the Triple Bypass, Copper Triangle, and Elephant Rock challenge riders with cumulative elevation gains often exceeding 8,000 to 10,000 feet. The riding season peaks between late June and early September when high-altitude snowpack melts from continental divide passes. Acclimatization is essential: starting rides above 5,000 feet and cresting passes over 11,000 feet demands steady pacing, consistent calorie intake, and warm layers for rapid alpine weather shifts. In return, cyclists experience jaw-dropping vistas of 14,000-foot peaks, crystal-clear mountain lakes, and a deep-rooted statewide cycling culture that celebrates every rider's summit achievement.
Terrain Characteristics: Epic Rocky Mountain passes, high alpine valleys, red rock canyons, and rolling Front Range plains.
Riding Season & Weather: May through September (High passes peak July–August).
