The Marathon de Cheverny begins at the Château de Cheverny in Loir-et-Cher, located in the Loire Valley. The main road races are structured around a marathon, half marathon, marathon duo, and a 10km event. This same event weekend also features the Trail des Châteaux de la Loire, offering 63km, 35km, and 14km trail runs, alongside children's races and a walking tour. Approximately 7,000 runners participate annually, creating a sense of a wide-ranging running festival rather than just a single-distance marathon.
The routes traverse the Sologne forest and wine country, guiding participants past vineyards, wine cellars, and sections near the châteaux of Chambord, Cheverny, and Beauregard. Cheverny includes a detail related to Tintin: Hergé based the Château de Cheverny on the model for Marlinspike Hall, Captain Haddock's residence. The event emphasizes local food and wine, with aid stations offering regional specialties, Cheverny and Cour-Cheverny wines, local products, music along the course, and many participants in costume. Its inclusion in the Challenge de la convivialité reflects the atmosphere; the weekend is as much about dining, socializing, and enjoying the château surroundings as it is about competitive racing.
