Goblin Valley Trail Runs

Goblin Valley Trail Runs takes place near Green River, Utah, over November 7–8, 2026. Saturday opens with the trail marathon (26.2 miles) at 7 a.m., the trail half marathon (13.1 miles) at 7:30 a.m., and the 10K and 5K at 8 a.m.; Sunday adds gravel rides of 69, 45 and 35 miles from 7 a.m. A one-mile fun run is offered for younger participants.

Courses wind among the natural rock formations known as hoodoos or goblins, on varied trails through protected landscape, so this is a weekend to run by effort rather than by pace. Coming from the roads? Plan a 16-week build for the trail marathon with the weekly long run moved onto unpaved ground, and accept a finishing time well off your road best. Families can pair a 5K with the kids' fun run.
