Event Details
Marathon Eryri, formerly known as the Snowdonia Marathon, was first held in 1982. The route encircles Yr Wyddfa (Snowdon), the highest mountain in Wales and England. Registration takes place at the Marathon Eryri event centre located in the car park area of the former Electric Mountain Visitor Centre in Llanberis.
Race Information
The event will be held on Saturday, October 24, 2026. Registration is open on the day before, Friday, October 23, from midday until 10:00 pm, and again on race day from 7:00 am until 10:00 am. Race packs are collected at registration.
Parking is available in pay-and-display car parks around Llanberis village, all within walking distance of registration. The organization encourages sharing transport or using public transport to reduce carbon emissions.
Course and Spectators
Spectators are encouraged along the route. The organization advises that the geography of the course can make spectating difficult and provides a spectator advice document.
There will be road closures on race day, including a rolling closure on Llanberis Pass (A4086) and sections of Llanberis High Street. A one-way system will be in place on part of the A498.

Prizes are specially commissioned by local artists. They are awarded for overall male and female positions, as well as age category winners (O40, O45, O50, O60, O70, O80), local winners, and team prizes (first team of three). A prize of £1000 will be awarded to any man or woman who breaks the race record. Visit the organization's website for the most recent information.
