Welcome to the River Thames Running website

We organise the River Thames Half Marathon on 25th October 2020 held in the lead up to the New York and Florence marathons.


Unfortunately, due to the Covid-19 pandemic, we have had to CANCEL this year's race. The River Thames Half Marathon will return next year on its usual date of the last Sunday in October, i.e. 31 October 2021. Stay safe and healthy and we hope to see you on the start line next year!

The beautiful Surrey town of Walton-on-Thames beckons runners on 31st October 2021 for a flat, fast, scenic and largely traffic free race.

Ideal for those looking for a PB or completing their first half marathon.

As well as the lovely course, runners like the enthusiastic and friendly marshals, the efficient organisation and the bespoke medal and well stocked goody bag. After the race, you will be able to download a free race certificate with your personalised finish time on it.

Now in its sixth year, the start and finish are at spectacular Walton Bridge, Surrey. The route follows the River Thames towpath and roads to the south west of London. It is a perfect preparation event if you are running a late autumn marathon or you just want the challenge of completing a half marathon.
