Pacing tips:
1. Managing the start: Don't let the early ramps get into your head. Settle into a measured tempo right from the bottom to avoid blowing up your heart rate and to save your legs for later.
2. Anticipating the changes: Use the easier sections (KM 2.5-3.5 and KM 5.0-5.5) to recover by easing off the effort a bit, without ever coasting.
3. Saving something in the tank: Even though the finish is less steep, fatigue will build up. Keep some power in reserve so you can hold a steady rhythm over the final kilometers.
