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.

  • How fast do I have to be?

    We strive to cater for all abilities on the event. As a guide, the minimum speed to complete your respective distance is approximately 4km/hr or 2.5mph in order to reach cut off times.

  • How will I carry my food and drink on event?

    Our pitstops are stocked with savoury and sweet snacks to keep you fuelled, so apart from any personal treats and an empty bottle to top up water at the stations, you should be hands free.

  • When do event entries close?

    The official closing date is midnight on Sunday 2 weeks prior to the event, however, the events can sell out which would result in registration closing earlier.
