Dodecaudax 200 Km Aout is a one-day, 200 km cycling randonnée held in Mozac, France, typically in August. Participants begin their ride from the gymnasium parking area, located within the 63200 postal code, with the event accessible from morning until evening.
The Mozac Cyclo Club organizes this event, which features a single 200 km road course. It is designed for cyclotourist participants rather than a closed-road race format. Licensed adult riders can enter without a fee.
