The Tartarus Backyard Ultra returns to Camp 7 in Riverside State Park, Spokane, Washington on August 15th, featuring a unique format that challenges runners and ruckers alike with relentless endurance tests over multiple hours. Runners compete in laps of 4.1667 miles while ruckers tackle shorter but equally demanding circuits of 2.2 miles each hour until only one remains standing.
Camp 7 at Riverside State Park offers a scenic yet challenging setting for the event, with firm and slightly soft trail conditions that are typical for mid-August in Spokane. Participants can expect to navigate through lush forest trails and along historic airstrips as they circle back hour after hour under varying weather patterns throughout the day and into night.

Participants will receive an acknowledgment for their likely DNF alongside the option for those who push through multiple hours to claim victory and earn special recognition.
Tartarus Backyard Ultra unfolds across Camp 7's trails, featuring firm yet slightly soft surfaces that provide both grip and challenge as runners and ruckers navigate hour-long laps. The race begins at exactly 8:00 AM from the old airstrip in Camp 7, with subsequent starts every hour until nightfall when races move to an out-and-back course on Centennial Trail.
Racers can expect typical mid-August weather conditions in Spokane during their event day.
