Rim Runner Trail Trek

Rim Runner Trail Trek is the final race in Yellowstone Rim Runners’ Free 3 Summer Race Series, held at Dover Park in Billings, Montana. The event features a 5K-ish trail course on Dover Park trails with scenic views. It’s described as a low-key club race that replaces the group runs, with snacks provided afterward.

It’s free for YRR members; non-members can register for $20. A key feature is its role as the concluding race of the Free 3 Series, with a chance to win cash through series awards—up to $25 for up to 10 members who complete all three races in person.
