2026 Marathon

The first Marathon Eryri (then called the Snowdonia Marathon) was held in 1982 and was the brainchild of local man Ken Jones. Following the success of the first London Marathon the year before, he really believed that something similar could work here in Eryri. He worked closely with John Disley and Chris Brasher (co-founders of the London Marathon) and delivered a race that was to become an iconic event on the running calendar. Ken organised the race again in 1983 before handing the reins over to the National Trust in 1984.
