About the race

Snowdonia in a Day is a challenging endurance event held in Snowdonia National Park, Wales. Participants traverse 60 km (40 miles) along the Snowdonia Skyline, gaining 4,500 meters in elevation while crossing 24 mountains across the Carneddau, Glyders, Snowdon range, and Nantlle. The route starts in Conwy in the east and finishes in Nebo in the west, primarily on mountain trails and high mountain terrain.

This fully guided and supported challenge includes experienced mountain runner guides, refueling stations with hot and cold food, transport between start and finish, and a support vehicle for drop bags. It is ideal for runners preparing for the Dragons Back race. Visit the organization's website for the most recent information.
