Starting in St. Niklaus and finishing on the Riffelberg or Gornergrat, the Zermatt Marathon is a demanding alpine running challenge with views of the Matterhorn.

What this race demands

The Gornergrat Zermatt Marathon demands sustained climbing capacity over a full marathon distance in a high-alpine environment.

Climbing volume

Accumulating 1840 meters of elevation gain across 42.2 kilometers requires consistent vertical endurance and muscular resilience in the quads and calves.

Alpine durability

Running a mountain marathon in July exposes athletes to variable alpine conditions and high-output efforts lasting several hours.

A target intake of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across an event lasting multiple hours.
