Snowdonia Marathon

Marathon Eryri (also marketed as the Snowdonia Marathon) is presented as a single-day marathon that circles Yr Wyddfa (Snowdon) and finishes in Llanberis. The event is promoted with the tagline “ICONIC. SPECTACULAR. UNFORGETTABLE.” and emphasises a demanding, scenic route that passes through Beddgelert, Waunfawr and the Llanberis area. The organiser pages and listings position the race as a ballot-entry event for 2026 and reference the long-standing history of the race.

This listing focuses on the core race experience rather than detailed logistics; start times, wave schedules and prize details are not published in the provided material and are referenced as available on the official site. Entrants are directed to the Marathon Eryri website and the site’s race-day and route pages for maps, athlete information and the official race FAQ. Participants are advised to consult the organiser’s race-day information closer to the event for final timings and practical instructions.
