River Thames Half Marathon
The River Thames Half Marathon takes place on 31 October 2027 in Walton-on-Thames with the start and finish at Walton Bridge. The route follows the River Thames towpath and nearby roads to Hampton Court Bridge and is described as flat, fast and largely traffic free.
The event distance is a half marathon (13.1 miles). The course is licensed and measured and is clearly marked. Terrain includes road, path, gravel and grass; participants should expect multi-terrain surfaces along the towpath.
Entries are restricted to runners aged 17 to 120 on race day. Early entry pricing and standard fees are listed, with an example non-club early bird price of £34.50 when valid. Race numbers are collection only; numbers can be collected on race morning behind Wilde Bagels Cafe or from local sports shops in the days before the event. Collection deadlines apply at those shops on the Saturday before the race.
The event provides marshals and sweep marshals along the entire course, professional first aid cover, and water stations at approximately 3, 5.5 and 8.5 miles plus at the finish; only water is supplied on the route. Prizes and vouchers are awarded to top finishers in each sex category, and finishers receive a bespoke mug and goody bag. Entries are non transferable and non deferrable; a full refund is offered only within 14 days of payment. Visit the organization's website for the most recent information.
