Brighton Backyard Ultra

Event overview

Brighton Backyard Ultra is an endurance running event held in Stanmer Park, Brighton, UK. The format requires participants to complete repeated laps of the same course until only one runner remains. Each lap is approximately 4 miles (6.7 km). All participants start together and must complete each lap within one hour to continue.

Format and course

The course is an out-and-back route that passes to the top of the park and returns along the same route. Runners pass through a livestock field and are asked to close gates and keep left on the route, running single file where needed. Laps begin precisely on the hour and must be finished before the next hour to be counted. Participants must show their race number at the Admin Gazebo as they finish each lap for it to be recorded. No personal aid is allowed while on a lap; common aid at the corral is permitted. Headphones are allowed but must not prevent awareness of hazards or emergency cues. Trekking poles and similar aids are not permitted.

Facilities and logistics

Entry includes support crew access, a medal, a pitch to set up a rest area or access to a rest marquee, basic hot and cold water, drinks and snacks, and event photography and videography. Participants must bring required kit: a torch (head, chest, or waist) and a hi-visibility item for darkness. Parking in Stanmer Park is public, paid, and first-come first-served; payments are made via the PayByPhone app. Visit the organization's website for the most recent information.
