Thames Bridges Challenge 2025

Participants at the Thames Bridges, walking across the bridge at sunset

Join 2,500 walkers and trek across the capital with unrivalled views of the skyline and landmarks.

From a Putney Bridge start it’s East towards the city, zig-zagging 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, it’s a party style finish line celebration and afternoon picnic in Southwark Park.

25km and 10km challenge options are available, and you can join as an individual or as a team.
