Battle of CamRock Returns August 29–30

The Battle of CamRock is almost here! Join us August 29–30 at CamRock County Park for the exciting finale of the 2026 Wisconsin Off Road Series (WORS). Whether you're an experienced racer, trying your first mountain bike race, or just looking for a fun weekend outdoors, there's something for riders of all ages and ability levels.

The weekend begins with Saturday evening's exciting short track races, followed by a full day of cross-country racing on Sunday. Racers and spectators can also enjoy onsite camping, great local food trucks, and a beer tent hosted by Sunshine Brewing.

The Battle of CamRock is one of CORP Trails' most important annual fundraisers, with more than 800 racers expected to attend. Every registration and every volunteer helps support the trails you ride all year long.

Racers Wanted

Registration is open now! Whether you're racing for the podium or just for fun, we'd love to see you on the start line.

Volunteers Needed

As a Trek-sponsored event, every volunteer role is filled by CORP supporters. No experience is necessary, and we'll provide everything you need to know. From course marshals to registration and finish line support, there are volunteer opportunities for everyone.

If you're able to lend a hand, please sign up soon to reserve your preferred shift. Your time makes this event possible!

We hope to see you at CamRock for a great weekend of racing, community, and trail support!
