Effort management tips:
1. Pacing the middle section: Resist the temptation to go too hard in the early kilometers. The goal is to reach the critical section (km 11-15) with energy in the tank.
2. Preparing for the final wall: The 10-11% gradient stretch is the decisive point of the climb. Select a gear that lets you keep a steady cadence and avoid blowing up your legs.
3. Making use of the brief easier sections: The 6% kilometers (km 8-9, 10-11, 16-17) offer short moments of active recovery. Use them to ease off the pressure a little and rehydrate.
