Lake City Alpine 50
August 23, 2025
Produced by Human Powered Endeavors, the Lake City Alpine 50 is an epic, 50-mile, alpine endurance bike race with around 6,000 feet of climbing starting in historic Lake City, Colorado.
This is NOT a mountain bike race and it is NOT a gravel race. It is a high-alpine endurance bike race unlike anything else out there. This lung-busting race will take you by the iconic Lake San Cristobal before a long, steep climb to the top of Cinnamon Pass (12,640 feet). You then descend the steep, rocky, pass and start up the very tough, steep, and long climb to Engineer Pass (12,800) feet. Another very long, rocky descent takes you back to Lake City. The race will feature 6,000+ feet of climbing through some of the most incredible sections of the San Juan Mountains.
