Stage 3 Breakdown:

Stage 3 bring the riders on a demanding 196km journey from Granollers to Les Angles. Following two stages around the area of Barcelona, the riders head into the Pyrenees for the first real mountain test of the Tour. The stage features nearly 3900m of climbing and five categorized climbs, with most of the elevation packed into the second half of the day.

The highlight of the day is the long climb of the Collada de Toses, followed later by the Col du Calvaire, which at 1,836 metres above sea level marks the highest point of the stage. Despite being the first mountain stage of the Tour, the climbs are not steep enough to guarantee attacks between the GC favorites. Instead, the stage looks perfectly suited to a strong breakaway. With the yellow jersey likely to change hands and the GC teams reluctant to control the race this early, plenty of riders will be eager to get into the breakaway.

The stage finishes with a 4.7km climb to Les Angles averaging 4.6%, with the final 1.7km up to around 6.5%. It is a finish that suits strong climbers with a fast finish rather than pure mountain specialists. If the breakaway gets enough freedom, the stage winner could also ride into the yellow jersey.
