Join 2500 walkers and trek 25 km across the Capital with unrivalled views of the skyline & landmarks – and you can fundraise for Challengers! 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.
Support Challengers by taking on this epic adventure on as an individual or as a team; you’ll get full support all the way, plenty of food & drink, optional camping & transfers, a special medal, T shirt & celebration finish – and a great sense of achievement! Push yourself further in 2026, take on an Ultra Challenge – the UK’s No. 1 Series of treks & trail challenges.
