Thames Bridges Ultra Challenge 2026

The challenge

Join 2500 walkers and trek 25km across the capital with unrivalled views of the skyline and landmarks, all while fundraising for Alzheimer's Society! From a Putney Bridge start it’s east towards the city, zigzagging over 16 historic bridges, each with a fascinating story, and a mid-point rest stop at The Oval cricket ground for snacks and drinks. 

25km later, beyond the majestic Tower Bridge, there’s a party style finish line celebration and afternoon picnic in Southwark Park. Sign up as an individual or as a team - you’ll get full support all the way, plenty of food and drink, a special medal, t-shirt and celebration finish. With a 10km option also available, there’s a Thames Walk for everyone!
