This 74.0 km loop rolls out of Aber-Wrac'h and follows the L'Aber Wrac'h river before turning inland past the Manoir de Trébodennic castle. The surface is 99% paved, with a small unpaved remainder, and 489 m of climbing keeps the legs honest. The route then returns by way of the L'Aber Benoît river and back to Aber-Wrac'h where it began.
