About the event

Join 2000 trekkers as we venture 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 fascinating story - and a midpoint stop at Kennington Oval for some snacks & drinks. 25km later, it's a finish line celebration in Southwark past the majestic Tower Bridge.
