IRONMAN 70.3 San Juan · Argentina: 90 km bike leg, 281 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
A point-to-point course at the foot of the Andes: from a reservoir at about 960 m, the first 13 km descend to about 780 m, the middle section rolls gently between 780 and 850 m until 55 km, and the second half eases down to about 620 m in the city of San Juan. Under 300 m of elevation gain, a net descent of about 340 m and thin air at altitude make it a fast course: hold your position on the descents and don't chase power on the rollers. April is autumn in the southern hemisphere, dry with strong sun.

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.

0 to 100, and the higher it is the easier it is to post a good time. Points come off for terrain, for corners, and for the heat and wind this race has actually had over the last five years at the same time of year. Full explanation in the article “How the course score works”.
