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

The Threshold Trail series combines two of the best-loved Ultra Marathon events in the UK. Whether you decide to run or walk, each event offers a unique challenge using a variety of terrains, gradients, elevations, distances and awe-inspiring landscapes.

Race to the stones - 13 - 14 July 2024

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.

Race to the king - 15 June 2024

Follow the path of Kings from ancient coast to sweeping ridges. Whether you are a first time Ultra runner or a hardened professional there is something to test everyone in this ultra accessible figure of 8 challenge. The hardest part might just be waving goodbye to your supporters at the festival camp.
