Pacing tips:
1. Save something for the end: Ride the first half, which is more rolling, at a controlled effort so you don't burn out before the steepest section (KM 15-21.6).
2. Anticipate the changes in rhythm: The gradient changes frequently. Get your gearing right so you can keep a steady cadence and avoid surging and stalling.
3. Break the climb up in your head: Focus on the succession of sections rather than the total length. Tackle the final part as a climb in its own right.
