Marathon Eryri : race summary
Marathon Eryri is a marathon event that runs around Yr Wyddfa (Snowdon) within Eryri National Park. The race was first held in 1982 and the route circles Snowdon, giving the event a distinctive place in the annual marathon calendar.

The race start is just outside Llanberis on the A4086 and the finish is in Llanberis; the event headquarters is at the Electric Mountain / former Electric Mountain Visitor Centre in Llanberis (LL55 4TA).
Registration takes place at the event centre on the day before and the morning of the race when runners collect their race packs. Spectator advice and race-route details are published by the organiser. Competitors are advised to carry suitable body cover because autumn weather can be challenging.
