Your challenge, your way

Join 2,000 trekkers as we venture 25km across the capital taking in unrivalled views of the skyline from its best vantage points.

Setting out from Putney Bridge – it’s east towards the City, zig-zagging over the array of historic bridges – each with its own fascinating story – and a midpoint stop at Vauxhall Pleasure Gardens for some snacks and drinks. 25km later, it’s a finish line celebration in Southwark past the majestic Tower Bridge.

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