The Des Moines Dirty Duathlon is Central Iowa Trails Association's annual bike / run race on single-track trails.
Join us for a fun day of mountain biking and trail running on Center Trails at Greenwood Park!
100% of the proceeds go toward maintaining and building our local single-track trails!
The course will incorporate professionally built single-track that passes through an old growth forest, including super fun, flowy downhill, a creek crossing, and plenty of lung-busting climbing.
Rock the Duathlon on your own, or partner up (1 runner, 1 cyclist) if you’re not ready to tackle the whole thing alone.
The free kids race will be either a "1 lap run and 1 lap bike", or "2 laps run and 2 laps bike" depending on ability. This will be held in the grassy area by the shelter and will not be utilizing the dirt trails.
Need a Partner?
Want to race on our amazing single-track trails but aren’t ready to conquer both the run and bike?
We will work to set you up with a perfect partner, so be sure to mention if you are a biker or runner and if you are “in it to win it” or “just along for the fun”.
