Tartarus Backyard Ultra

The Tartarus Backyard Ultra is a unique running and rucking event held at Camp 7 in Riverside State Park, Spokane, WA. Following the last person standing format, participants must complete laps within an hour, with runners tackling a 4.1667-mile loop and ruckers a 2.2-mile loop. The race continues until only one runner and one rucker remain, who must then complete a final loop to claim victory.

The event encourages fundraising, allowing participants to waive registration fees by raising funds for a cause. Amenities include water, coffee, and portable toilets, with camping options available nearby. Visit the organization's website for the most recent information.
