Endure24 Leeds is a 24-hour trail relay at Bramham Park near Leeds, run on 8km loops through the day and night in early July. Runners can enter solo, as a pair, or in teams of up to 12, aiming to complete as many laps as possible before the clock runs out. It is the UK's biggest 24-hour trail race, attracting first-time fun runners, club runners, charity entrants, and experienced ultramarathoners. Team pricing scales by group size, charity places start lower than standard entries, and solos and pairs receive practical support like their own camping area and a bag drop near the course.
The loop uses wide, runnable trails inside historic Bramham Park, passing through forest and open heathland before going by landmarks such as the 18th-century Temple of the Lead Lads and the Roundhouse. The race has a campsite feel as much as a stopwatch feel, with food, drink, spectators, and runners moving in and out through the same base area for a full 24 hours. Solo runners chase their own limits, pairs split the load between two people, and bigger teams rotate while some members rest. A race tradition is the 100 Mile Club, rewarding runners who reach that mark with an exclusive yellow T-shirt, and charity fundraising is built into the event, with participants raising thousands for good causes each year.
