This 30 mile Ultra Marathon will test your limits as it takes you through the heart of the Brecon Beacons on beautiful, but technical trails. 

The ultra starts at Georgetown boys and girls club in Merthyr Tydfil and works its way onto the Taff Trail. After a few miles, you will split away to follow the trails alongside the River Taff heading north towards the Brecon Beacons Reservoir.

With friendly marshals, well‑placed checkpoints, and a community that loves the outdoors, this is an ultra that you will not forget.

This is a great route for those looking to take the step up to a trail Ultra marathon whilst also catering to experienced ultra runners.
