Like a rave but for adult bike riders.

The Vapor Trail 125 is a legendary mountain bike ultra-marathon that launches riders into Colorado’s rugged wilderness at 10 PM on September 6, 2025, in Salida. Covering 125 miles and climbing 17,000 feet, this self-supported race challenges participants with technical singletrack, remote jeep roads, and relentless alpine climbs, all under the stars. Cyclists push through sub-freezing cold and midday heat, navigating demanding terrain and breathtaking high-mountain landscapes. Only about 70% make it to the finish line, making this a badge of true endurance and adventure.
