 There was also a mountains classification, for which points were awarded for reaching the top of a climb before other riders.Each of the twenty-three climbs were categorised as either first, second, or third-category, with more points available for the more difficult, higher-categorised climbs.For first-category climbs, the top six riders earned points; on second-category climbs, four riders won points; on third-category climbs, only the top three riders earned points.
