London Backyard Ultra

London Backyard Ultra

London Backyard Ultra takes place at Frylands Wood Scout Outdoor Centre on 29th August 2026. The race follows the Backyard Ultra format: participants must complete four miles each hour, on the hour, and continue running another loop at the start of the next hour. Runners stop when only one competitor completes a final loop alone.

The event package includes an entry ticket, a participant medal, and a winner trophy and medal. Facilities listed for this edition include a pitch to set up a rest area and a limited rest marquee for those without a pitch. Parking is available for one car per entrant with visitor parking on a first come, first served basis. Hot showers and hot and cold water are provided. Organisers also supply drinks and snacks during the event and arrange photography.

The site notes that limited support infrastructure is available, such as the rest marquee and single-car parking, so participants should plan equipment and crew needs accordingly. The format requires repeated hourly loops of four miles, making the event a test of pacing, recovery, and endurance on a repeating short course.
