Official event pageWhat this race demands
Oh Meu Deus – Ultra Trail Serra da Estrela demands sustained physical and mental endurance to cover a 100-kilometer trail running distance across the mountains and historic villages of central Portugal.
Ultra Distance Endurance
Covering 100 kilometers on foot requires a high level of aerobic capacity, structural resilience, and pacing discipline to manage fatigue over many hours of continuous movement.
Terrain Adaptability
Traversing mountain ranges and historic schist villages means navigating variable trail surfaces that demand ankle stability, technical descending skills, and muscular durability.
Given the ultra-distance nature of a 100 km trail race, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy levels and prevent profound glycogen depletion.
