Event Format

This is a 7-hour timed event where participants choose their own distance. The minimum distance is 3 km, achievable via a turn point within a lap. A full lap is approximately 7 km (subject to change to a 5.3 km loop). Participants can run as many or as few laps as they like within the time limit. Three laps equal a half marathon, six a marathon, and seven or more an ultra marathon, including a 50 km distance.

Course

The course follows a scenic stretch of the River Thames. It is fully signed, requiring no navigation. The surface is mainly well-made paths and tarmac with a short grass section. Road shoes are suitable year-round. The exact course may change slightly near the event date following a safety review.

Amenities and Perks

An aid and drinks table is located at the start/finish of each lap, offering a selection of savory, sweet, fruit, cheese, and vegan items. All finishers who complete at least 3 km receive a medal and a goody bag, with a vegan option available. Distance pins for half marathon, mega-half, marathon, 50km, and ultra are awarded to those who achieve the respective distances. Special numbered bibs are available for milestone runs (e.g., 50th, 100th event) upon request.

Facilities

Toilets, changing facilities, and a café are available at the race HQ. There is an unmanned bag drop area near the start/finish line, but valuables should not be left. A large pay-on-exit car park is located at Runnymede Pleasure Grounds. Visit the organization's website for the most recent information.
