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 course ideal for both first-time half marathoners and those aiming for personal bests. Participants can expect enthusiastic marshals, efficient organization, and a bespoke medal, along with a well-stocked goody bag.

The route follows the beautiful River Thames towpath, making it a perfect warm-up for late autumn marathons. Runners will also receive a free race certificate with their finish time. Visit the organization's website for the most recent information.
