Rim Runner Trail Trek 2026

The Rim Runner Trail Trek is a Wednesday evening 5K trail race held at Dover Park, beginning at 6:00 PM Mountain time. This event serves as the trail race in the Yellowstone Rim Runners' Free 3 series. This series offers runners a road race, a track race, and a dirt-trail race, replacing the club's typical Wednesday night group runs. The course covers approximately 5K on dirt trails, acting as the off-road conclusion following the Rims to River 8K and the Rim Runner Mile. Yellowstone Rim Runners members participate without charge, while non-members are required to pay $20. Members who complete all three Free 3 races in person are eligible to receive $25 cash.
