The Semi-marathon d’Argentan is a half marathon held in Argentan, a town in the Orne department of Normandy. The primary event is the standard 21.0975 km distance, though participants can also form a two-person relay, with each runner completing approximately 10.5 km. This is a local event with a limit of 600 entries, and recent participation has been around 500 runners.
The race typically begins at the Champ de Foire and proceeds through Argentan in October, with event materials often referencing the autumn foliage of Normandy. Having been held for about forty editions, it is a well-established part of the local running schedule. The nickname “Ramène ton flouz” adds a lighthearted local character, and the relay format accommodates pairs seeking the race atmosphere without completing the entire half marathon distance.
