The Vapor Trail 125 is an ultra-endurance Mountain Bike Event. Those words are a sort of label that doesn't really cover what the Vapor Trail 125 is. It's a bike ride that starts at 10 PM on a bridge over the Arkansas River at 7,000 feet elevation. For roughly 2 hours riders climb the slope of the Sawatch Range to over 10,000 feet. They ride through the night, and most of them through the next day never dropping back below 9,000 feet until the last 8 miles. It can rain, it can snow, it can be windy and/or cold. There are multiple climbs to the Continental Divide, one climb to 12,600 feet elevation. Roughly 20,000 of cumulative climbing.
