The Longbridge 100 Backyard Ultra's

The Longbridge 100 Backyard Ultra

The Longbridge 100 Backyard Ultra is a last-person-standing loop race held in Alfriston with Winter and Summer editions. Competitors run repeated laps on a fixed course; each lap must be completed within one hour and each new lap begins one hour after the previous one. Runners must be inside the starting corral when the bell signals the next lap or they will be recorded as DNF and cannot continue. Assistance is allowed only between finishing a lap and entering the starting corral; once a lap has started a runner must proceed alone. Non-competitors and eliminated runners are not permitted on the course during laps.

Each lap is 4.2 miles (6.78 km) on a route that mixes single paths and farm access roads with chalky flint and gravel underfoot. Winter elevation is listed as 180 m and Summer elevation as 190 m. The event uses the Webscorer timing app plus manual lap recording. A token system at the second turnaround requires each runner to collect and return a token on every lap; failure to return a token leads to disqualification.

Entries are limited (maximum 50 per race) and the Summer Silver Ticket allocation includes 50 general sale places with 10 reserved for a waiting-list ballot. Entry includes access to covered barn space, a small aid station with water, fruit and snacks, first aid cover, toilets and charging power. Refund policy: 100% up to 8 weeks if sold out and waiting list enacted, 50% up to 4 weeks if sold out and waiting list enacted, no refund less than 4 weeks. Female runners who become pregnant after registration may defer or obtain a refund. Visit the organization's website for the most recent information.
