Marathon Eryri

Marathon Eryri is a marathon held around Yr Wyddfa (Snowdon) in Eryri National Park. The event began in 1982 and uses a route that encircles Wales’ highest peak. The course starts just outside the village of Llanberis on the A4086 and finishes in Llanberis. The race headquarters and registration are based at the former Electric Mountain visitor centre in Llanberis.

Registration and race-day arrangements are handled from the event centre. Runners can use several nearby pay display car parks within walking distance of registration. Organisers encourage reducing car miles through lift sharing and use of public transport. The nearest main railway station is Bangor, with bus connections to Llanberis, and the nearest major airports are Liverpool and Manchester, each about two hours by car.

Participants are advised to carry some form of body cover because weather in late October can be changeable. Road closures and temporary traffic systems are put in place along parts of the route on race day. The event includes junior races in addition to the marathon.

Prizes are awarded in male and female overall positions, a range of age categories, local categories and team prizes. A monetary prize is offered for anyone who breaks the race record. Visit the organization's website for the most recent information.
