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 Vauxhall Pleasure Gardens for some snacks & drinks. 25km later, it's a finish line celebration in Southwark past the majestic Tower Bridge.
