About This Event

Produced by Life Time Events, the team behind the Leadville Race Series and Unbound Gravel, The Rad Dirt Fest showcases the remarkable terrain around Trinidad, Colorado. Set against the backdrop of towering Spanish Peaks and expansive mesas in late September, this event has quickly established itself as a premier gravel destination in southern Colorado’s high desert.

Three distinct routes cater to different ambitions and abilities. The Frijole covers 47 miles with 4,632 feet of climbing, offering smooth gravel paths and manageable terrain for newcomers or those seeking a more relaxed day. The Anteloop stretches 68 miles with 6,558 feet of elevation gain, combining desert landscapes with views of snowcapped peaks and sections of champagne-smooth gravel. The flagship Stubborn Delores presents a serious challenge at 113 miles and 10,613 feet of climbing, reaching its highest point at 8,921 feet in a mesmerizing alpine setting.

All three routes feature a signature two-mile technical gravel section on the South Shore Trail within Trinidad Lake State Park, adding a distinct challenge to each course. The terrain varies from buttery smooth surfaces to more demanding technical stretches, with the longer routes showcasing the dramatic elevation changes and diverse landscapes that define this region bordering the San Isabel National Forest and Spanish Peaks Wilderness Area.

Aid stations are strategically positioned throughout each course, with strict cutoff times enforced on the longer routes. The Stubborn Delores requires reaching Spanish Peaks Inn by 1:20 pm and Trinidad Lake State Park by 7:40 pm. Weather typically brings temperatures in the 80s during the day, cooling to the 50s in early morning, though the high desert climate can be unpredictable.

The event maintains a festive atmosphere with comprehensive awards ceremonies recognizing 20 categories for the two longer distances and four categories for the Frijole route.
