Official event pageWhat this race demands
This 139 km ultramarathon with 6000 m of elevation gain requires exceptional muscular durability and sustained effort over a very long duration.
Extreme Distance
Covering 139 km requires profound aerobic endurance and the ability to manage continuous forward progress over an extended period.
Massive Elevation Change
Accumulating 6000 m of climbing demands specialized leg strength for sustained ascents and robust eccentric muscular endurance to handle the inevitable descents.
Pacing Discipline
The combination of high mileage and substantial climbing requires strict early-race restraint to prevent premature fatigue.
Given the extended duration, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy levels and prevent major caloric deficits.
