Snowdonia National Park hosts Marathon Eryri on 24 October

Snowdonia National Park (Eryri) will host Marathon Eryri on 24 October 2026, with the race starting near Llanberis and finishing in the village. The event brings a course encircling Yr Wyddfa, the highest peak in Wales, to the national park during October.
For visitors, the race is also an access story. Llanberis, the principal gateway for the mountain, will have temporary road restrictions while runners pass through the area.
Marathon Eryri starts and finishes around Llanberis
Marathon Eryri begins just outside Llanberis on the A4086 and finishes in the village, according to the Marathon Eryri race information. The organiser lists registration at the former Electric Mountain Visitor Centre car park on Friday 23 October 2026 and again on the morning of Saturday 24 October.
The race was first held in 1982 as the Snowdonia Marathon. Its route continues to circle Snowdon, linking the event directly with the mountain landscape rather than using Llanberis simply as a start-line settlement. That connection makes the October race relevant to visitors exploring the wider park as well as to runners.
Snowdonia National Park frames a mountain race
Snowdonia National Park was officially designated on 18 October 1951. The authority’s history records Llanberis among the locations where information centres later opened, reflecting the village’s long-standing role in helping visitors understand the park.
Yr Wyddfa rises above the park as Wales’ highest mountain, while the Llanberis Path is one of the established routes towards its summit. The park authority classifies that path as hard or strenuous. The marathon’s course therefore uses a setting shaped by steep mountain terrain, public paths and working communities, rather than a closed urban circuit.
The race date falls five days after the park’s designation anniversary on 18 October. That timing places a long-running sporting event within the same month as a significant date in the park’s institutional history, while the start and finish keep the visitor focus on Llanberis.
Road restrictions will shape access on 24 October
The organiser says Llanberis Pass will close temporarily as a rolling restriction on race day. Part of Llanberis High Street will also be closed, while restrictions and a one-way system will affect roads through Beddgelert and the surrounding route.
The practical effect is local rather than a general closure of Snowdonia National Park. Visitors can still plan around the wider landscape, but anyone heading to Llanberis, Beddgelert or the race route on 24 October 2026 should allow for altered vehicle access and follow signs and marshals.
