After your Zumba style warm-up we head east from Bishop's Park and over Putney Bridge towards the City of London. We'll zig-zag over the array of 16 historic bridges (each with its own fascinating story) throughout the capital for 25km.
Following the River Thames, there is a midpoint stop after you've crossed Vauxhall Bridge where you can get some snacks & drinks. It's then onto a finish line celebration in Southwark past the majestic Tower Bridge.
This an excellent opportunity to get out, get fitter, meet others, and explore the very best of London!
