The San Juan Crucible is part of the Colorado Endurance Series, a free series focusing on endurance events in the southwest. The 2016 race will be the first annual attempt of this race. There are two mileage options, the 90 and 150. Route descriptions and elevation data are linked for each distance on the left. The routes follow each other until mile 79 where they split. Either loop can be ridden on a cyclocross/gravel bike or any mountain bike.
This ride is self-supported and self-navigated. You must be comfortable using GPS.
