Get active and soak up the capital's history
The full route heads through Charlton, along the Thames Path to Greenwich and the O2, Old Royal Naval College and the fabulous Cutty Sark. It's then onto central London – crossing the Thames via the Millenium footbridge, past the Tower of London, and on to the Olympic Park, before returning to Woolwich.
A route steeped in history with iconic sights, and capped with a BBQ and bar at the finish – making for a wonderful end of summer celebration!
With 50km, 25km and 10km challenge options available, there's a challenge for everyone. You can join as an individual or as a team.
