Thames Path Ultra Challenge

Explore the unique history of London by taking on the Thames Path Ultra Challenge!

England’s greatest river provides a fantastic backdrop for an unforgettable challenge, which you can take on at your pace as a walk, jog, or run – and fundraise for Winston’s Wish!

Over 3,000 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. Sign up as an individual or as a team; you’ll get full support all the way, plenty of food and drink, optional camping & transfers, a special medal, T shirt and celebration finish. With 50km, 25km and Henley 10km options also available – there’s a Thames Path Challenge for everyone! Push yourself further in 2026, take on an Ultra Challenge – the UK’s No.1 Series of treks & trail challenges!
