Trek across the Capital taking in unrivaled views of the skyline, and historic landmarks. Setting out from the Putney Bridge start and head East towards the City, zig-zagging over 16 historic bridges–each with its own fascinating story–with a rest stop near Vauxhall Pleasure Gardens, before reaching the spectacular Tower Bridge and completing your challenge at Southwark Park, it’s a party style finish line and is great way to enjoy a weekend in London.


Your entry includes a range of free food & drink at regular rest stops, and support from medics, marshals and massage teams. As you cross the finish line, you’ll get a glass of fizz, t-shirt, and a special medal to celebrate your achievement!
