Tips for managing your effort:
1. Pacing: Start easy over the first 3 km (gradients of 3-7%) to save something in the tank before the 10%+ sections.
2. Prepare for the key sections: Km 10 to 12.0 (12% gradient) and km 13 (13%) are the toughest. Keep something in reserve so you can tackle them without blowing up.
3. Keep a steady cadence: Use a gear ratio that lets you maintain a consistent pedaling cadence, especially on the long 9-11% stretches that make up most of the climb.
