List of every Ultra-Marathon Race in Wales

Whether you are looking for a fast, flat 50km blast along the Pembrokeshire Coast Path or a brutal 200-mile mountain expedition across the spine of the country, the Welsh ultra-running calendar is more vibrant than ever. From the jagged, technical ridges of Eryri (Snowdonia) to the rolling, expansive trails of the Cambrian Mountains and the Banau Brycheiniog (Brecon Beacons}, finding the right race requires more than just a date and a location, it requires data and data is what we work in here at FindTrail.

This is the most comprehensive, runner-first database of ultra-marathons in Wales. We have cataloged every event across the country from local hidden gems that cost next to nothing to enter, to world-renowned mountain tests, to give you a transparent, data-driven look at what each race really involves.
