Staged by Vacation Races, the course offers forest views on the edge of Custer Gallatin National Forest, with packed dirt, loose rock, and light town sections—great scenery with a bit of trail grit. The weekend pairs a Friday evening 5K with a Saturday morning half marathon, and many runners tackle both as the Bison Double for extra swag and a bonus medal. All events are centered at the Old Airport Road lot in West Yellowstone, keeping logistics simple for runners and spectators. Trail shoes are recommended due to the uneven, technical surface.
