Jeanne started competing at 9 years old with a pony named Heritage Harcourt. She competed in her first French Championships at 10 and rode her first international competitions at 13. Jeanne then competed in both pony and children circuits with great success and in 2015, she wore the French colours at the Children European Championships. The year after, she took part in the Pony European Championships before winning her first international Grand Prix in 2016 with her pony Rominet de Bruz during the CSIOP of Fontainebleau.
Now turned on the horse circuit, Jeanne also pursues her education as she would like to follow medical studies later.
