Pacing tips:
1. Managing your pace on the first section: Resist the urge to go too hard in the opening kilometres (10%-12%) and save your legs for the critical sections at the end.
2. Anticipating the hard finish: Keep some physical and mental reserves for km 11 to 13, the steepest part (12%-14%), where your speed will naturally drop.
3. Holding a steady cadence: Choose a gear ratio that lets you keep a consistent pedal cadence despite the changing gradients, especially on the 8-9% stretches that make up most of the climb.
