Thames Meander Autumn 2026

The Thames Meander - Autumn is a flat riverside race series in Richmond, commencing and concluding at the Petersham & Ham Sea Scouts HQ on Petersham Road. Participants can select from 10km, half marathon, or marathon distances, with all three utilizing the Thames Path towpath for out-and-back courses. The format is straightforward: run alongside the river, turn at the designated checkpoint for your chosen distance, and return to the original finish area. The 10km turnaround point is at Kew Gardens Car Park on Ferry Lane. The half marathon extends to the Thames Path opposite Barnes Sports Club. The marathon follows the same 13.1-mile out-and-back course as the half marathon, run twice. The path is suited for consistent running, not technical trail running, and as a public thoroughfare, runners will encounter walkers and cyclists. Marshals are stationed along the course and at turnaround points. Checkpoints provide gels, drinks, electrolyte powders, and high-energy food. KLP Medics are present at the start/finish and Kew Gardens Car Park.
