Sole Survivor Backyard Ultra - Richland, WA

Sole Survivor Backyard Ultra is a backyard ultra format trail event in Richland, WA, organized by Nomad Trail Runners. The course is a repeated loop of 4.16667 miles that begins with a short out-and-back pavement section and then follows single track. Each loop has about 40 feet of elevation gain, is roughly 30-40% shaded, and includes some rocks and roots plus one short steep climb of about 6-8 feet.

The event runs in hourly cycles: runners start the same loop each hour and must complete the loop within 60 minutes to remain in the race. The event continues until only one runner completes a final solo loop; that runner is the sole finisher and all other entrants receive DNF. Speed within a loop does not matter; the requirement is to complete the full loop before the hour expires. Runners may use the time between loops to rest, eat, change, or nap, but they must remain on site and start the next loop at the scheduled time. No pacers are allowed and crews must stay in the parking area and may not hand items to runners after a run starts.

One aid station is located at the start/finish with typical aid station food, abundant ice, and hot soup for overnight runners. There will be a barbecue at dusk and some pop-up canopies; participants may camp in their space. Service animals are allowed on course; pets are not.
