About Tour de Dirt
Tour de Dirt is Oklahoma’s premier mountain bike championship series—run by racers, for racers. Our mission is to host an annual series of competitive cross‑country (XC) mountain bike races where riders earn points throughout the season and compete for series awards across age groups and skill levels.

Fun fact: Tour de Dirt is the longest‑running mountain bike race series in the United States.
