Heading north from the granite-and-slate cottages of Auray (population 12,000) to the port town of St. Brieuc (population 46,700), this shorter stage will likely see the peloton split by the frequent climbs and crosswinds. The crowds will be thickest on the Cat. 3 “wall” at Mur-de-Bretagne, 92km into the stage, which could spring a key attack. The tricky run-in to St. Brieuc loops down to a narrow valley before climbing up into town and features another uphill finish.
