Sole Survivor Backyard Ultra - Richland, WA
Sole Survivor Backyard Ultra is a timed backyard ultra held in Richland, WA at 1200 Carrier Rd. The format requires all runners to start a 4.16667-mile trail loop at the top of each hour and complete that loop before the hour ends. The sequence repeats each hour until only one runner remains; that final runner must complete one additional solo loop to become the finisher. The race may continue overnight and into the next day.
The course begins with about 0.4 miles of pavement to spread runners, then continues on mostly flat single track with occasional rocks and roots. Each loop has roughly 40 feet of elevation gain and one short steep climb of about 6 to 8 feet. The route is about 30 to 40 percent shaded. Course markings and a route map are provided.
There is one aid station at the start/finish offering typical aid station food and ice. Hot soup will be available for overnight runners and a BBQ may be provided at dusk. Pets are not allowed on course during running except service animals. Crews may stay in the parking lot but cannot act as pacers or hand items to runners after the hourly start.
This event is an affiliate of Big's Backyard. Runners who reach 100 miles will receive a custom belt buckle and the event may provide up to $500 toward airfare if the winner is granted entry to Big's Backyard. Registration opens Feb 1, 2026.
