2. Recover on the flat bits. Use the 1% section at km 1.0-1.5 to spin your legs out, eat and drink, and settle back into your rhythm before the steeper sections.
3. Hold a steady cadence in the final. At 9% over km 8.0-8.5, shift into an easier gear, stay seated, and keep a smooth, consistent cadence all the way to the summit.
