Event overview

The Cirencester basecamp marks the start of the 100km looped route through the heart of the Cotswolds, providing a stunning setting for 2,000 adventurers to test themselves.

Rolling hills, villages, the Cotswold Way, footpaths and trails, with some fabulous views en route. You’ll get full support and hospitality, including optional ‘university style’ accommodation at basecamp, and with three-quarter, half, quarter and a Cirencester 10km distance option also - there’s a Cotswold’s 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.
