What the course asks of you
The first climb, the Somport, is long and gradual and takes you into France with the whole day ahead. The Col de Marie-Blanque is short but brutally steep in its last kilometres; after it comes the long climb back to Spain over the Portalet, the highest point of the day, and finally the Hoz de Jaca, a short climb late in the ride.
The Somport invites riders to go too fast in a big group, and the Marie-Blanque punishes them for it. Climb the first two passes below your threshold and keep eating: the Portalet is long, and it comes after more than 100 km.
How to prepare
The general shape of a good preparation, which Event Coach turns into a plan for your fitness, time and date:
- Train long climbs: steady efforts of 30 to 60 minutes just below your threshold match the cols of the Quebrantahuesos far better than short intervals.
- Build the long day: rides of five to seven hours in the final two months, towards the 200 km of the route you choose.
- Practise eating and drinking on a schedule, and descending: a mountain day is as much going down as going up.
Pacing mistakes to avoid
The mistakes that cost riders the most on a day like this:
- Treating the first climb of the Quebrantahuesos as a race: a long col ridden above the pace you can hold for hours costs you the rest of the day.
- Saving nothing for the last climb, where the most kilometres are already in your legs.
- Skipping food on the descents: the next climb starts with what you ate on the way down.
