Held on 13 September 2025, the Thames Bridges Trek (part of the Ultra Challenge series) invites walkers to journey east across London—crossing iconic bridges including Albert, Millennium, London, and Tower—on a flat 25 km riverside route from Putney Bridge to Southwark Park. The optional 10 km route starts at The Oval and still takes in key landmarks like Blackfriars and Tower Bridge. The event features full support with covered rest stops, snacks, drinks, medical aid, marshals, and GPS tracking via app, plus a festive finish line celebrated with medals, T-shirts, and bubbly. Organized by Ultra Challenge in collaboration with charity partners (including NSPCC, BHF, Mind, SPEAR, etc.), participants can walk self-funded or support a charity through a variety of fundraising packages.
