Join more than 2,000 walkers and trek 25km across London with unrivalled views of the skyline and landmarks. Set out from Putney Bridge and head East towards the City, zig-zagging over the Thames across 16 historic bridges, each with a fascinating story. Enjoy a rest at your mid-point rest stop in The Oval Cricket Ground with plenty of snacks and drinks. At the end of your epic 25km journey, you’ll head over Tower Bridge to a celebration and afternoon picnic in Southwark Park. Sign up as a team or an individual and get ready to experience full support every step of the way.
