London | Saturday 12 September 2026
10km and 25km distance options | walking only event
Weโre thrilled to be taking part in the Ultra Challenge Series Thames Bridges Trek on Saturday 12 September 2026 to raise funds for Celia Hammond Animal Trust and we invite supporters, friends, and family to also join us for a great day out in London. Every step you take will help us care for stray, abandoned, and unwanted animals.

Join 2,500 walkers and trek 25km across the capital – with unrivalled views of the skyline and landmarks โ and fundraise for Celia Hammond Animal Trust.
From a Putney Bridge start itโs east towards the City of London – zigzagging over 16 historic bridges, each with a fascinating story โ and a mid-point rest stop at The Oval Cricket Ground for snacks and drinks. 25km later, beyond the majestic Tower Bridge, itโs a party style finish line celebration and afternoon picnic in Southwark Park.
You can sign up as an individual or as a team and youโll get full support all the way including plenty of food and drink, a special medal, t-shirt, and celebration finish. With a 10km option also available, thereโs a fabulous Thames Walk for you!
Will you join us?
