About the event
Walk, jog, or run the Thames Path Challenge, tracing the course of England’s iconic River Thames. This incredible journey begins in the leafy suburbs of South West London, following the river’s winding path to Hampton Court, through the historic Runnymede—famous for the Magna Carta—and finishing at Henley-on-Thames with a celebratory BBQ and festivities.
As the flattest of all Ultra Challenge routes, the terrain offers a mix of paths that will test your endurance while rewarding you with stunning landscapes, charming villages, and historic towns along the way.
With different distances to choose from there's a challenge for everyone! Sign up and fundraise for London’s Air Ambulance Charity and you’ll get 50% OFF the standard charity place registration fee!
