About International Snowdon Race
This mountain race up Snowdon in North Wales suits experienced fell runners looking for a serious test of fitness and technique. Held on 17 July 2027, the International Snowdon Race covers 15 km of trail terrain with nearly 1,000 metres of elevation gain. The route climbs steeply—averaging a 13.4% gradient with pitches reaching 32%—before descending back down to Llanberis.
Entry is restricted to runners aged 18 and over with prior mountain running or fell racing experience. The race runs under UK Athletics rules, and electronic timing is embedded in race numbers, which must be visible at both the summit and finish. In severe weather, organisers may require runners to carry windproof and waterproof clothing, a hat and gloves, with a potential cut-off time of 1 hour 5 minutes at Clogwyn.
