Our full Thames Path Challenge 100km route heads from Putney Bridge, past Hampton Court to Runnymede – of Magna Carta fame – at 50km, then on past wonderful historic scenery to Henley. With half & quarter distance options available too, there's a challenge for everyone. No matter your chosen distance though, you'll be supported all the way by our team, and rewarded with an amazing sense of achievement. Go the distance and help raise funds for children with serious or terminal conditions, along with their loved ones.

What funding options do I have?
Charity Sponsorship – you pay a small registration fee; do lots of fundraising and we cover the cost of your event place!
Mixed Funding – pay half of the event place cost yourself; fundraise a bit less and we pay the balance of the event place cost.
Self-Fund – you pay the full cost of the event place; fundraise whatever you want, with no set target or deadline, and there’s no cost at all to the charity!
When fundraising, we would advise that you set up a JustGiving page. It is the most effective way for you to fundraise! If you have any questions about this, please get in touch.
