The Threshold Trail Series combines the four 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.
The Threshold Trail Series is for all levels and abilities.
We pride ourselves on making our events as inclusive as possible. This is done by offering a support package like no other. All our events come with snack and drink laden pit stops, experienced medical staff and, for those who decide to take it on across two days, the ultimate overnight experience at our Basecamp.
Run or walk in the same footsteps as travellers did 5,000 years ago. The oldest path in Britain ‘The Ridgeway’ offers more than its fair share of challenges. It is the original trail series event and also the flattest!
Walk, jog, or run the ultimate trail through the best parts of Northumberland. You’ll be treated to mysterious woodland, open moorland, beautiful coastline and a number of historic castles. And you finish at the mesmerising Bamburgh Castle!
Try an Ultra steeped in history and starting and finishing at the iconic Goodwood Racecourse. Explore two equal, but very different loops in this incredible part of the world with a variety of terrain and landscape that will challenge and inspire in equal measure.
If you love your hills and stunning views, this one is for you! The fourth event in our series takes you along the Cotswold Way. You will be faced with an array of epic inclines and descents which take you up, and down; some of the best scenery Britain has to offer.
Our series won the Gold award for the best Trail Race Series and the Silver Award for the best Event Series at the 2020 Running Awards.
