Join #TeamHDA and be one of the 3000 challengers walking, jogging, or running towards the finish line 


Event information:

Start by heading over Putney Bridge onto the south side of the River Thames and the iconic towpath, then head upstream through Richmond, by Hampton Court, and out to Runnymede and Windsor. There's some wonderful scenery on route as the city turns to countryside, all along a flat and fast path.


Join as an individual or as a team and get ready to experience full support from the Action Challenge team every step of the way.
There will be regular rest stops packed with food and drink, hot meals, fully marked routes, massage and medical care as well as marshals on course and walking the route with you.


There’s a range of camping options and transfers available for all challengers so you can plan your whole weekend.

Walk, jog, run for charity
