Get your walking shoes on and explore some of London’s hidden gems on this tour of the ‘gateway to London’ along the Thames’s eastern stretch. Head out from basecamp next to the grandeur of Woolwich Barracks on marathon, half-marathon, and 10km routes. Expect sites like Greenwich Riverside, the Thames Barrier, and Tower Bridge on the full marathon route.
Fundraise by walking these routes steeped in history, with full route marking, regular rest stops packed with food and drink, a lively warm up and event atmosphere, and capped off with a BBQ meal, bar, and music at the finish.
Take on the London Summer Walk and get ready for the perfect Challenge to close out summer.
