The Grand Prix Duathlon de Gravelines is a short-format duathlon held in Gravelines, located in France's Nord department. It is scheduled for April, with the specific date yet to be confirmed. The race format is Duathlon S, a compact run-bike-run event, not an extended endurance challenge.
The course is straightforward and flat, featuring a 5 km run, a 20 km bike leg, and a concluding 2.5 km run. The total elevation gain is only 20 meters. The event is designated Open DUA S-OPEN, indicating it is an open short-distance duathlon rather than a race exclusively for a championship. It is not part of a larger series, and no results have been posted on the source page.
