The UK’s best supported Ultramarathons built to test elite runners to first timers

Ultramarathons are never easy. However, we set out in 2012 with a mission to make them more open. We want everyone to be able to experience the unforgettable feeling of completing a 100km trail race whether it takes them 8 or 28 hours.

In the last decade, we have welcomed thousands of men and women from across the globe to take part in our award-winning UK ultras. Whether you’re a first-time walker or looking to break the course record, our community is ready to welcome you on to the UK’s most popular ultramarathons.

Have you got what it takes to conquer the oldest path in Britain?

Find out for yourself what draws 3,000 people from around the world each year to follow in the footsteps of Romans, Vikings and mythical warriors in their quest to reach the ancient stone circle at Avebury. The UK’s favourite ultramarathon.
