Suffolk Backyard Ultra Festival
Saturday, 5 June 2027 · High Lodge, Thetford Forest, Brandon · organised by Challenge Running
How you get in
Entry advice. The format: one 4.167-mile loop starting on the hour, every hour, from noon on the Saturday. Finish inside the hour and wait for the next bell. Miss the start or fail to finish in the hour and you are out. The last runner to complete a lap nobody else completes wins; everyone else is officially a DNF.
No overall cut-off and no knowable end date: the 2026 edition ran four days.
Feeds At-Large places to Big's Backyard Ultra world championship. 12-hour and 6-hour options exist but have no winner and no prizes.

Nobody else keeps this. It is why the sell-out log starts now rather than when it feels useful.
