Team Sky and one of its riders won the overall classification for the third year in succession, as Geraint Thomas became the first British rider to win the race.[3] Thomas won the third stage of the race, taking the leader's fuchsia jersey as a result, and ultimately won by seven seconds ahead of Thibaut Pinot (FDJ), who finished all five stages within the top-five, including a stage win on the final day. The podium was completed by AG2R La Mondiale's Domenico Pozzovivo, a further thirteen seconds in arrears of Pinot.
In October 2016, it was announced that the race would expand from four to five days.[4] The route for the race was announced on 17 February 2017.[5]
The second stage, initially scheduled to be run over 195.8 km (122 mi),[5] and to start in Innsbruck, was shortened due to snow.[6] The third stage was also shortened due to snow; from 143.1 km (89 mi),[5] to 137.5 km (85 mi) but remaining at its scheduled start and finish locations.[7]
In the 2017 Tour of the Alps, four different jerseys were awarded. The general classification was calculated by adding each cyclist's finishing times on each stage. Time bonuses were awarded to the first three finishers on all stages: the stage winner won a ten-second bonus, with six and four seconds for the second and third riders respectively. The leader of the general classification received a fuchsia jersey; this classification was considered the most important of the 2017 Tour of the Alps, and the winner of the classification was considered the winner of the race.
The second classification was the sprints classification, the leader of which was awarded a red jersey. In the sprints classification, riders received points for finishing in the top three at intermediate sprint points during each stage. Points were awarded on a 6–4–2 scale for the first four stages, while the points were doubled for the final stage.

There was also a mountains classification, for which points were awarded for reaching the top of a climb before other riders. Each of the ten 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 five riders earned points; on the other climbs, only the top three riders earned points. The leadership of the mountains classification was marked by a green jersey.
The fourth jersey represented the young rider classification, marked by a white jersey. Only riders born after 1 January 1994 were eligible; the young rider best placed in the general classification was the leader of the young rider classification. There was also a classification for teams, in which the times of the best three cyclists in a team on each stage were added together; the leading team at the end of the race was the team with the lowest cumulative time.
