What this race demands
Quebrantahuesos demands sustained climbing capacity and deep endurance over a 200 km Pyrenean loop with 3500 meters of elevation gain.
Climbing volume
The 3500 meters of vertical gain spread across the course requires repeated, sustained efforts on long ascents into the Pyrenees.
Endurance capacity
Covering 200 kilometers demands rigorous aerobic conditioning and pacing discipline to sustain output over many hours in the saddle.
Mountain descents
Crossing into France and navigating Pyrenean terrain requires bike-handling skill and focus on extended descents.
A June gran fondo of this distance will likely exceed six hours for most riders, requiring a consistent intake of 60 to 90 grams of carbohydrates per hour to sustain energy levels.
