From a Putney Bridge start it’s East towards the City, zig-zagging over 16 historic bridges – each with a fascinating story – and a mid-point rest stop at The Oval Cricket Ground for snacks and drinks. 25 km later, beyond the majestic Tower Bridge, it’s a party style finish line celebration and afternoon picnic in Southwark Park.
