The Experience

The Outlaw Trail Ultra Half Marathon, set in the scenic Sawtooth National Forest near Hansen, Idaho, provides a welcoming entry into the world of trail ultras. This point-to-point race begins at the Diamondfield Jack Campground, offering a mostly downhill journey towards Third Fork Campground.

The initial three miles navigate the rough jeep/ATV terrain of Deadline Ridge Road, before transitioning to over 10 miles of "sweet single-track trail." While described as having an easier elevation profile, one runner noted technical sections and overgrown single-track that required careful navigation. The race aims to introduce runners to trail ultras with a shorter, more accessible distance.

With approximately 85 finishers in recent editions and a steady field trend, the Outlaw Trail Ultra draws participants from around six states. A loyalty rate of about 31% suggests a dedicated following for this event, which first appeared on record in 2023 and is now in its third year. The race's name honors Diamondfield Jack, an early outlaw of the region.
