Black Barn Backyard Ultra

The Black Barn Backyard Ultra is a Last Runner Standing event in Bonney Lake, WA, held on October 2, 2027. The race uses the backyard ultra format: competitors must complete a loop of 4.167 miles every hour. Each loop begins precisely on the hour and must be finished before the next bell for the loop to count.

Runners must be inside the starting corral at the bell and start each loop on time. Each loop must be completed within one hour. No late starts or outside aid during a loop are allowed, and non-competitors and eliminated runners may not be on the course. Artificial aids such as trekking poles are prohibited. Slower runners must allow passing. Water and a limited supply of prepackaged food items are available at the start/finish area; otherwise runners are responsible for their own aid and nutrition.

Prizes are accumulated in a visible jar with a $100 contribution added before each new loop. The last runner to complete a loop is the winner; the runner who completed the second-longest distance is the assist. The jar contents are split with the winner receiving 75 percent and the assist receiving 25 percent. If no one completes one more loop than everyone else, no winner is declared. Runners who reach 24 laps (100 miles) receive a custom engraved belt buckle. All other finishers receive a medal engraved with their laps and a T-shirt subject to available sizes and quantities.
