Ultra Challenges
The UK’s No 1 Series of treks & trail runs! Take on a challenge at your pace and fundraise for Samaritans. From the Cotswolds to the Thames Path, across magnificent countryside or trails, you’ll get full support all the way – including plenty of food & drink, medics & massage, camaraderie, a medal & T shirt – and an amazing sense of achievement. With 20 events to choose from, and distance options ranging from 10km up to the full 100km – there’s an Ultra Challenge waiting for you in 2026.
