The event takes place on July 18, 2026 in Casper, Wyoming, with parking, start/finish, and post race festivities at the Casper Mountain Trails Center (9301 Casper Mountain Rd, Casper, WY 82601). Participants can choose between a two-lap 8 mile option or the Backyard Ultra format based on a 4.17 mile lap.

For the 8 mile option the lap direction alternates by year: even numbered years use a clockwise direction and odd numbered years use a counter clockwise direction. For the Backyard Ultra, a coin toss will determine the direction for each lap.
