Official event pageWhat this race demands
The Kalkkögeltrail requires sustained climbing strength and mountain running endurance to cover 42 kilometers and 3030 meters of elevation in the Stubai Alps.
Vertical climbing endurance
Accumulating 3030 meters of elevation gain over a 42-kilometer distance demands exceptional uphill efficiency and muscular endurance for prolonged ascents.
Technical descent capability
Navigating the mountain terrain of the Kalkkögel peaks requires the physical durability to handle heavy eccentric loading during sustained descents.
Given the substantial duration of a 42-kilometer mountain marathon with over 3000 meters of climbing, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy output.
