🏆 About Tour de Dirt
Tour de Dirt is a nonprofit mountain bike race series run by racers for racers, celebrating Dirt. Community. Oklahoma. We host competitive, timed XC races across Oklahoma, with divisions for all ages and skill levels. A core part of our mission is Kids Kup, our youth program for riders 12 & under that helps grow the next generation of Oklahoma cyclists. As the longest‑running mountain bike series in the U.S., Tour de Dirt is proud to support local trails, riders, and communities across our state.

 🏁 How to Race
All racers are required to make a one‑time $25 purchase for a season race plate with an integrated timing chip (replacements only needed if lost or damaged). Please note: this purchase is separate from race registration. 👉 Still need yours? Be sure to grab your Tour de Dirt plate before race day
