Dogged Dumoulin wins
The Frenchman was part of an early four-man breakaway and held off his rivals in a sprint for the line to triumph in the 208km stage from Saint-Malo to Nantes.
The Confidis rider just edged America’s William Frischkorn (Garmin Chipotle) into second, with France’s Romain Feillu (Agritubel) third and Italy’s Paolo Longo Borghini (Barloworld) fourth.
