About this run
The Capital Backyard Ultra is a unique endurance challenge set to take place in Lorton, United States on March 20, 2027. This event operates on a "last person standing" format, meaning runners will complete a 10 km loop every hour, with the race continuing until only one participant remains. The Capital Backyard Ultra offers a test of mental and physical fortitude. Participants will gather at the start line each hour, ready to tackle the next 10 km loop.
