Sole Survivor Backyard Ultra, Richland WA

Sole Survivor Backyard Ultra is a repeat-loop endurance event organized by Nomad Trail Runners in Richland, WA. This is the seventh running of the event; the organizer notes the race day was moved to a Saturday for this edition. The format requires runners to complete a set loop each hour until only one runner remains.

The loop is 4.16667 miles long and begins with about 0.4 miles of pavement before entering mostly single-track trail. The course has roughly 40 feet of elevation gain per loop, is 30 to 40 percent shaded, and contains rocks, roots, and one short steep climb of about 6 to 8 feet. Trails are marked and a map of the route is available.

There is one aid station at the start/finish offering typical aid station food, plenty of ice, and overnight hot soup options including vegan and chicken noodle. A BBQ may be provided at dusk. Crews and spectators may stay in the parking area but may not run the course or act as pacers. Pets are not allowed on course during running; service animals are permitted.

Race rules require presence before each hourly start, adherence to whistle warnings, and completion of the full loop within 60 minutes to remain in the race. Runners who reach 100 miles (24 hours) receive a custom belt buckle. The event is an affiliate of Big's Backyard Ultra; a winner may be eligible for championship entry and possible airfare support.
