Course rankings · speed score
0–100: the higher, the easier it is to ride fast. The score combines terrain, corners and the typical race-day heat and wind. Tap any course to start planning on it.

How the score works
Climbing density (how many meters you climb per kilometer on average) x1.8. The more you climb, the more it costs to hold speed, and this is the biggest of the four factors.
How dense the corners you actually have to brake for are, x0.13: only turns of more than 25 degrees count, so the natural bends of an ordinary road cost nothing. A turnaround is 180 degrees on its own.
Above 24C on race day, 1.2 points per degree; below 10C also costs a little. The temperature is the measured average for this event over the same period in the past five years.
Typical race-day wind speed x2.2: the resistance of a headwind, plus the effort a crosswind costs you in handling and holding position. Also measured over the same period in the past five years.
How to read it: score = 100 minus the four deductions (floor 30). The ranking uses “typical race-day conditions”: terrain and corners from the actual route, heat and wind from the last five years of that event's race week. Once you pick a date on the race plan page, the weather switches to that day's forecast and the score moves with it.
