Self Transcendence 24 Hour Track Race and British 24 Hour Championships
This 24 hour track event is held annually in September at Tooting Bec Athletics Track in London. The race measures how far competitors can run in 24 hours by completing repeated laps of the track. It was first held in 1989 and has produced national and world best records. The 2026 edition incorporates the British 24 Hour Championships and is an IAU Bronze Label event held under UK Athletics permit Level 2.
The event is organised by the Sri Chinmoy Marathon Team in conjunction with Run and Become. The field is strictly limited to 55 competitors and is open only to runners with recent ultrarunning experience of at least 100 km or 12 hour duration. A waiting list operates when entries exceed the limit and selection is based on prior experience and potential.
Race support includes lap counters, sports physiotherapists, a race referee and time keeping officials, plus trackside refreshments available throughout the event. Competitors receive multiple race numbers including a chipped number for timing. Direction on the track is changed every four hours. Facilities at Tooting Bec include space for tents and support stations, a large tent for kit bags, indoor changing rooms, a heated physiotherapy room, portable toilets and a trackside food service offering hot and cold drinks, snacks and meals. Live results and an on site scoreboard provide ongoing distance updates. Visit the organization's website for the most recent information.
