Thank you for your interest in the Thames Path Ultra Challenge, unfortunately sign ups are now closed. If you are interested in taking on an alternative Ultra Challenge please see our Ultra Challenge events, or view our full events calendar for more options.
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 Acorns!
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 and transfers, a special medal, t shirt and celebration finish. With 50km, 25km & Henley 10km options also available – there’s a Thames Path Challenge for everyone!
Push yourself further in 2026 for Acorns and take on an Ultra Challenge – the UK’s number one series of treks and trail challenges!
