Thames Path Challenge

7-8 September 2019

Thames path challenge walkers next to the river

Choose from 100km, 50km, or 25km trek distances on this stunning walking challenge. Fundraise for our vital leukaemia research, and test your endurance to the max in London this summer with the Thames Path Challenge.

You can sign up for a solo trek or gather your friends and tackle this as a team for our charity. The scenic routes are steeped in history, following the winding Thames at your own pace: walk, jog or run, and choose the distance that suits you!

The full route begins at Bishop's Park, next to Putney Bridge, and on through leafy Kew and Richmond, past the last non-tidal lock at Teddington. It passes the royal palace of Hampton Court, beneath Windsor Castle and on through beautiful countryside to Henley.

Join the 'Main Thames Path Challenge' – 100km from Putney Bridge to Henley or on either 50km Half Challenge, or a 25km Quarter section. Most will walk at their own pace, some will jog, and quite a few will run the whole course!
