Chrono des Nations – Les Herbiers Vendée is a single-day individual time trial road bicycle race held annually in October in Les Herbiers, Vendée, France. Since 2005, the race is organized as a 1.1 event on the UCI Europe Tour.
It was originally called Chrono des Herbiers but in 2006 the race merged with the now defunct Grand Prix des Nations to create the currently called Chrono des Nations.[1]
