The Challenge
Join 2500 walkers and trek 25 km across the Capital with unrivalled views of the skyline & landmarks – and you can fundraise for your favourite charity! 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 & drinks. 25 km later, beyond the majestic Tower Bridge, it’s a party style finish line celebration & 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 & drink, a special medal, T shirt and celebration finish. With a 10 km option also available -there’s a fabulous Thames Walk for you!
