Go from sea to mountains in this unique trail race ending in Eryri (Snowdonia) National Park

The spectacular Eryri 80K returns for the second year in the Eryri by UTMB programme, offering a tough and rewarding journey from coast to mountains. The 78km route climbs 2,500m, starting at sea level in Caernarfon before heading inland into the mountains in the heart of Eryri. The course links coastal paths, remote trails and high mountain ground, capturing the scale and variety of North Wales.

The race starts at 20:00 on Friday, sending runners out from the coast and into the night as they work their way towards the mountains. Finishers will earn 3 Running Stones, making them eligible for the Hoka UTMB Mont-Blanc lottery. Built for experienced trail runners, this is a race that demands steady effort, good judgement and respect for the terrain. A true test from the shoreline to the high peaks.

The top 3 runners will not get automatic qualification to UTMB World Series Finals.
