Official event pageWhat this race demands
Mammutmarch is an extreme endurance walking event covering 100 kilometers through the natural landscapes of North Zealand. It demands uninterrupted forward locomotion over an exceptionally long duration.
Continuous Durability
Covering 100 kilometers entirely on foot requires sustained muscular endurance and structural resilience to withstand repetitive impact over many hours.
Pacing Discipline
The extreme distance dictates a conservative initial pace to prevent premature fatigue and manage cumulative physical strain.
Metabolic Management
A continuous multi-hour walking effort requires consistent caloric intake to sustain energy output and prevent severe depletion over the course of the event.
A continuous effort of this duration requires a steady intake of 45 to 60 grams of carbohydrates per hour to maintain energy levels and support prolonged output.
