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.
