The terrain on this course
- Flat (±1.2%) makes up 63%
- No significant climbing: what matters is handling the wind and holding your power steady
Speed score
Rolling terrain is where you overspend without noticing: 20 extra watts on every little rise adds up and empties your legs for the back half. Let power touch the top of the range on the small stuff and leave it there.
