Rip it up off-road at Texas' oldest off road multi-sport event!
There is something for everyone, so come spend the weekend camping, running, and riding at beautiful Rocky Hill Ranch. Awesome trail runs on Saturday morning, the Bike Toss World Championships on Saturday night. Sunday morning is the original Dirty Du. There's also the Dirty Du Sprint.
Don't mountain bike? No worries, this event is perfect for relays!
