La Ronde du Phacochere is a mountain bike ride held in Saint-Aubin-d'Aubigne, located north of Rennes in Brittany. Participants begin at the Salle Polyvalente on Rue des Cordiers. Morning registration opens at 08:00, and the event concludes by 13:00. This is an affordable local club event. Entry fees are 3 EUR for licensed riders and 6 EUR for those without a license, for both adult and junior categories.
The primary routes consist of off-road loops measuring approximately 20, 40, and 50 km. The associated climbs are around 230 m, 460 m, and 600 m, respectively. Some sources indicate slightly shorter distances of 22, 37, and 47 km, suggesting that exact distances may vary by edition. However, the structure remains consistent: multiple VTT options are available, ranging from a short, easy ride to a longer, more challenging route. The event is organized by the Saint-Aubin cycling club, which is also known by the names L'amicale cyclo, Cretes et Vallees, or Amicale Cyclo St Aubinoise.
