About This Race

The 50-mile course strikes a balance between serious ultra distance and accessibility, offering substantial challenge without the extreme commitment of the hundred. This middle-ground option allows runners to experience extended time on the island while maintaining a more manageable training and recovery timeline. The distance provides ample opportunity to encounter the island's wildlife and shifting desert conditions.

The course traverses Antelope Island's diverse terrain of rolling hills, ridgelines, and open grasslands with commanding views of the Great Salt Lake. Runners navigate a mix of singletrack trails and dirt roads across the island's unique high desert ecosystem. The terrain features moderate but persistent climbs and descents, with the island's highest peaks providing panoramic vistas of Utah's Wasatch Mountains and the expansive salt lake below.

The island's isolation creates an intimate racing experience with dramatic views across the Great Salt Lake to the Wasatch Mountains.
