Official event pageWhat this race demands
Ultra Trail Serra da Freita requires exceptional climbing efficiency and sustained muscular durability to manage 6900 meters of elevation gain over a 100 km mountain route.
Climbing volume
The extreme ratio of elevation gain to distance demands continuous uphill capability, requiring athletes to efficiently hike and run steep mountain gradients for hours.
Descent durability
Traversing rugged and technical mountain trails over 100 km places high eccentric loading on the lower limbs, requiring resilient quadriceps and joints to absorb repeated impacts.
Endurance pacing
As a 100 km ultramarathon completed in the summer heat of late June, the event demands strict adherence to an aerobic pacing strategy to prevent early systemic fatigue.
Given the extended duration of a 100 km mountain ultramarathon, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy availability.
Estimated finish times
