Zermatt, Valais, Switzerland
The Gornergrat-Zermatt Marathon July 3-4 is a multi-distance mountain running event centred on Zermatt in the Valais region of Switzerland, organised under the Gornergrat-Zermatt Marathon (GZM) brand. The event portfolio includes an Ultra Marathon, Marathon, Half Marathon, TOP20RUN (Zermatt–Gornergrat), a relay option and a children's Hörnli Kids Run, and the organisers use the tagline “Accompanied by amazement”. The official website hosts route maps, GPX files, start lists, bib collection information and an event guide that covers arrival, accommodation, safety and medical services.
The site highlights high-altitude finishes, substantial ascent profiles and alpine scenery around the Matterhorn and Gornergrat, together with partner services such as Swiss Runners Ticket travel for competitors. Practical details such as bib pick-up locations and times, transfer-of-number policy (contact [email protected]), and on-route refreshments/checkpoints are published on the official pages; competitors are advised to consult the event guide and starting times pages for the latest schedule. Training camps and preparatory runs under the GZM brand are listed separately on the same site for those seeking acclimatisation ahead of the race weekend.
