Teams of four take turns running laps on a fast, scenic 2.5 km urban trail loop with runnable paths and mixed trails. Over a 4-hour window, the objective is to complete as many loops as possible; for example, 13 laps make up ~20 miles, 17 laps ~a full marathon, and 20 laps ~50 km (Ultra). Strategy matters — team pacing, rest, rotation all affect how far you go. The format is designed to be inclusive, suitable for clubs, crews, or friends, whether you’re new to running or more experienced. The events are planned for multiple UK cities (starting with London, then Birmingham & Manchester), complete with race villages, entertainment, and partner activations.
