IRONMAN 70.3 Monterrey: 90 km bike leg, 449 m of climbing. Elevation profile, what the terrain asks of you, the weather this race day usually brings, and how to pace this course.
Course intel
Two laps on the dedicated lanes of the Constitución expressway. The organizers describe it as almost entirely flat, with only the rises of a few interchanges, and the road surface is very good. About 540 m of elevation gain, mostly from the bridges. Mid-March in Monterrey is hot and dry, and it warms up fast in the afternoon.

The terrain on this course
- Flat (±1.2%) makes up 70%
- 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.
