Thames Path Ultra Challenge 2026

The 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 while fundraising for Alzheimer's Society! 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. 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 2027, take on an Ultra Challenge – the UK’s number one series of treks and trail challenges!
