Off-Road Sprint Duathlon Race

Du or Du Not; There is No Tri!
The Off-Road Duathlon combines fast, flowing trails and rugged terrain for a challenge that’s as rewarding as it is beautiful. Designed for athletes who thrive on variety, this event pairs mostly flat, fast run segments with a mountain bike course featuring smooth flow sections and a few technical elements to keep things exciting.

Set in the heart of Colorado’s mountain landscape — with potential venues like Granby Ranch or Devil’s Thumb Ranch — it’s the perfect balance between adventure and accessibility. Whether you’re chasing the podium or just testing your limits, this course invites every athlete to push a little harder and have a lot of fun.

Each event will include opportunities to give back — from food drives supporting Community Table to youth race scholarships — ensuring every mile makes a difference beyond the trail.

• Fast, scenic trail runs and flowy MTB routes
