About the race
River Thames Half Marathon is a flat, fast, scenic half marathon held in Walton-on-Thames, Surrey, with the start and finish at Walton Bridge. In its sixth year, the course follows the River Thames towpath from Walton-on-Thames to Hampton Court Bridge, offering views of the non-tidal Thames and largely traffic-free sections. The event is known for a friendly atmosphere, enthusiastic marshals, efficient organisation, and a bespoke medal with a well-stocked goody bag.
Runners can download a free personalised finish-time certificate after the race. Entry starts from £34 and the event is chip-timed under Run England race licence. It’s ideal for PB attempts or as late autumn marathon prep. Visit the organization's website for the most recent information.
