IRONMAN 70.3 Versailles: 88 km bike leg, 676 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
Through the Chevreuse valley: the well-known Côte de la Vacheresse (1.6 km, 4.6%), 6 km of forest roads around the Abbaye des Vaux de Cernay, and the 17 Tournants (1.3 km, 5.7%), a favourite of local riders. About 740 m of elevation gain, short steep climbs alternating with smooth fast sections, and mid-October outside Paris is cool.

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.

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”.
