Official event pageWhat 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.
Estimated finish times
Estimates by level, not promises. Your own number depends on your fitness on the day.
