Foulées du Bassin potassique is a Sunday-morning road running event in Staffelfelden, Alsace. The programme features a 10 km race, with a marked finish chute and enough competitive edge for course records to matter; one women’s 10 km winner improved the old mark by a single second.
The race has reached at least its 19th edition, indicating it is not a one-off village run. Reports from the event suggest a local, friendly field, with fair play noted even when runners faced autumn weather, a cold wind, light rain, and strict public-health rules. The 10 km winner was interviewed after finishing, and the series has also had to cancel when gathering limits made public road events impossible.
