River Thames Half Marathon

The River Thames Half Marathon, set in the picturesque towns of Walton-on-Thames and Weybridge, invites runners for a scenic and largely traffic-free race. Scheduled for October 26, 2025, this event features a flat and fast course along the River Thames towpath, making it ideal for both first-time half marathoners and those aiming for personal bests. Participants can expect enthusiastic marshals, efficient organization, and a well-stocked goody bag, along with a bespoke medal and free race photos.
