The inaugural Snowdonia Marathon was held in 1982, and was conceived as a dramatic alternative to the numerous city and town races becoming so popular. The demanding and spectacular route, encircling Snowdon, Wales’ and England’s highest peak, has given the event a unique place in the annual marathon calendar ever since. Source
