31 May Ascension day
The Journée Sportive (which many call “Ascension day”) is one of Roseans’ favourite traditions. For 24 hours, the student committee takes control of the campus and sets up dozens of sport games, ranging from a traditional tug of war to football on a soapy surface to human-powered water skiing and many other madcap games. (Those who remember a TV show called Jeux sans frontières will get the idea.) It is one of those days remembered with great fondness by all anciens when they look back on their time at Rosey.
