Stage 4 Breakdown:

Stage 4, takes the riders on a rolling 181.9km journey from Carcassonne to Foix. After the first mountain finish in the Pyrenees, the route is slightly easier, but with around 2800m of climbing it is still a demanding day. The final categorized climb comes more than 35 kilometres from the finish, making this a stage that looks perfect for a strong breakaway rather than a showdown between the GC favorites.

The riders leave the medieval city of Carcassonne and head through the foothills of the Pyrenees before reaching the two main climbs of the day. First comes the Col de Coudons, a steady 10.5km climb at 5.5%, before the shorter but steeper Col de Montségur (6.9km at 6.6%) offers the last real chance to make a difference. From the summit, a long descent and rolling roads lead into Foix, where the fast finale should suit riders who can get over the final climb with a small gap.

With the sprinters expected to lose contact on the climbs and the GC teams unlikely to control the race, the battle to get into the breakaway should be fierce. If the right group gets away early, they have a very good chance of staying clear all the way to the finish.
