IRONMAN 70.3 Buenos Aires・Palermo: 90 km bike leg, 198 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
Three loops, 90 km, entirely on Buenos Aires highways, flat and straight, under 500 m of elevation gain and mostly from overpasses. A typical steady-power course; watch the cost of slowing and re-accelerating at the U-turns between loops. Early October is spring, and wind off the river estuary is common.

- No significant climbing: what matters is handling the wind and holding your power steady
Speed score
The wind here is part of the terrain: ride the headwind sections to your range, not to the speedometer, and in crosswinds relax your upper body and stay low. The plan already has wind in every segment, so just ride the numbers.
Historical race-day weather (around 10-04): 15.4°C · Wind 4.3 m/s
