Snowdon24

Yr Wyddfa Snowdon24 is a 24-hour ultra-trail challenge based in Llanberis at the foot of Yr Wyddfa, Snowdonia peak. Solo runners aim to ascend and descend Snowdon as many times as possible in 24 hours, with UTMB-indexed options including 50k, 100k and 100-mile challenges, making it a UTMB Mont Blanc qualifier. It can also be run as a relay for teams of up to five, ideal for colleagues or friends raising funds.

The course showcases spectacular Snowdonia scenery, with marshals and Mountain Leader support, a lively event village, finishers’ mementos and precise timing. Cancer Research Wales is the charity partner. Visit the organization's website for the most recent information.
