Brighton Backyard Ultra

Brighton Backyard Ultra is an endurance event held at Stanmer Park Nature Reserve, Falmer, Brighton, BN1 9RG on 08th May 2027. The course length for Brighton is 4 miles and 880 feet (approximately 6.7056 km). The Brighton route is an out-and-back: runners go to the top of the park or trail and return along the same route.

The format requires completing one loop every hour. Each loop must be finished within one hour; any remaining time in the hour is for recovery. A new loop begins on the hour and competitors must be inside the starting corral when the bell rings to start the next loop. The event continues until only one runner remains; the last remaining runner must complete one final loop alone to be declared the winner. Failing to complete a loop within the hour results in a DNF.

Courses are fully marked with fluorescent caution signs, directional arrows, and marshals. Competitors must carry a head torch, chest torch, or waist torch; high visibility clothing is strongly recommended for night loops. The Brighton event includes an entry ticket, participant medal, winner trophy and medal, limited rest marquee for those without a pitch, a pitch to set up a rest area, hot and cold water, drinks and snacks, and event photography and videography. Event rules restrict personal aid on the course, artificial aids, and accompaniment by non-competitors while active on a loop. Visit the organization's website for the most recent information.
