Looking for a Summer Challenge?

Explore. Ride. Stamp. Win. This summer, turn your gravel rides into an adventure with the Deschutes River Basin Gravel Passport Book! All the routes are from the Deschutes River Basin Gravel Guidebook.

The program has been extended to October 31, 2027 due the historic 2026 summer fires in Oregon and limited accessibility to many of the routes.

From now through October 31, challenge yourself to ride as many Dirty Freehub routes as possible in the Deschutes River Basin Passport. Every route you complete earns you a stamp—and every stamp earns you another chance to win awesome prizes.

Here’s How It Works
