After leaving Chartres, Saint-Jacques by bike head for llliers-Combray, town which inspired Marcel Proust for his mythical book "A la recherche du temps perdu". The places mentioned in his famous work: the Pré Catelan or the house of Tante Léonie, now the Marcel Proust Museum, immerse you in the atmosphere he created. There is also a gentle transition to a more hilly territory, between Beauce and Perche.
