How the score is calculated

Tailwind follows your route at your pace, reads the wind and weather at each point, and adds them up into one score from 0 to 100.

Tailwind works out where you will be at each moment of the ride, at your speed, and samples the forecast at those points. A ride that starts in calm air and finishes in a storm is scored for exactly that.

How the number is built

1. It starts at 55. That is a calm day, a pure crosswind or a loop that is half tail and half head.
2. Tailwind adds up to 42 points. The more of the ride with the wind behind you, the higher it goes.
3. Headwind takes off up to 52 points. Riding into the wind hurts more than riding with it helps.
4. Light winds count for less. The effect grows until about 8 m/s (around 29 km/h), when wind counts in full.
5. Crosswind costs a little too.
6. Weather takes off up to 40 points. Rain is the main cost. Dry rides get a small bonus.

Why your score changes

Your score moves when the forecast changes, when you choose a different departure time or when you change your average speed. Changing your speed changes when you reach each part of the ride. Your weight does not affect the score.
