Get active and explore some of the capital’s historic areas with a tour of the gateway to London along the Thames’s eastern section.

Starting alongside the grandeur of Woolwich Royal Artillery Barracks, our full 50km looped route heads through Charlton and along the Thames Path around the Greenwich Peninsula, passing the O2, the Old Royal Naval College and the fabulous Cutty Sark. Then you’ll trek through central London, crossing the Thames via the Millenium Bridge. You’ll pass the Tower of London and go on to the Olympic Park, before returning to Woolwich via the foot tunnel.

The route is steeped in history with many iconic sights along the way, topped off with a barbecue and bar at the finish, making for a wonderful end-of-summer celebration!

As Dementia UK is an official partner of this event, you will receive a 50% discount on the ‘full sponsorship’ registration fee when signing up to support families affected by dementia.
