There are sections along the ride which have extra sprint points attached. You sprint to them, and if you're first (or second, or third), you get extra points (which go towards the green jersey).
Thanks! So it's not a matter of sprinting and posting a good time between two points then? So the breakaway group have taken the points just now, even though they're not necessarily sprinters?
