Join 2000 walkers and trek across the Capital taking in unrivalled views of the skyline, and historic landmarks.

Setting out from the Putney Bridge start we head East towards the City, zig-zagging over 16 historic bridges – each with its own fascinating story – and a mid-point rest stop at The Oval Cricket Ground for some snacks & drinks.

25km later, it's a party-style finish line celebration in Southwark Park past the final crossing – the majestic Tower Bridge.

Your entry includes free food and drink at regular rest stops, plus support including medics, marshals and a massage. As you cross the finish line, you'll get a glass of fizz, t-shirt and a medal to commemorate your achievement.
