England’s greatest river provides a fantastic backdrop for an unforgettable challenge.

Over 3000 adventurers will join the Putney Bridge start, and the full 100km route heads upstream to Henley along the famous Towpath. It’s through Richmond, Hampton Court, Runnymede, and Windsor, with some wonderful scenery to a riverside finish line.

With three quarter, half, quarter distance options also available – plus the separate 25km Thames Bridges Trek & The Moonlight 10 Walk through Central London as part of the weekend ‘festival’ – there’s a Thames Challenge for everyone!
