The 10 km Magny is an urban 10 km road race held in Magny-le-Hongre, a commune located in Seine-et-Marne within the Île-de-France region of France. It takes place in mid-March, offering participants a spring road race in a town situated just outside the immediate bustle of Paris.
The race features a single 10 km distance contested on city streets, with the event also contributing to a charitable cause. Its slogan, “Magnyfeste ton envie!”, is a play on the town’s name, lending the race a distinct local and informal character, contrasting with the atmosphere of a large-city marathon.
