The Semi-marathon de Monéteau is a flat half marathon held in Monéteau, near Auxerre in Burgundy. The start and finish are located together on the Route d’Auxerre. Approximately 600 to 700 runners participate annually, making it a significant event on the local racing schedule. It has held a regional designation for over two decades, serves as a qualifier for the French championship, and hosts the half-marathon championships for Yonne and Bourgogne-Franche-Comté.
The course consists of a single measured loop that travels through Monéteau's neighborhoods and returns toward Gurgy, avoiding repeated laps and inclines. The participant field is diverse, with runners originating from 27 French departments and 10 regions, in addition to around 50 entrants from Germany. A 5 km race is also available alongside the half marathon. Half-marathon participants must register before race day, with bib collection available on Sunday morning.
