Event overview

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

The Ultra Challenge Experience

This challenge is part of the UK's number one series of trek and trails runs for a wide range of ages, fitness and experience levels.

Choose your challenge and do it at your pace. The level of support enables you to go further, whilst enjoying the great outdoors, camaraderie, and the challenge. There are marquee rest stops, lots of food and drink, medical and massage teams, with a fully signed route to guide you.

A big finish-line celebration awaits with an amazing sense of achievement and once the aches subside you’ll feel energised, up for more of life’s real challenges – and, maybe, personal horizons redefined.

We were so impressed how well organised it was. From registration to the finish line everything was amazing - the staff were so lovely and helpful - the catering was outstanding and all the facilities clean and tidy. A huge thank you to you all!!

Such a good feeling crossing that finish line after 100km of walking. I must say a special thanks to the guy doing the massages at the 78km stop at around 5.30am. I may not have made it without his healing hands! Great event, well organised and would recommend that experience to anyone!
