Morgan competed successfully in the youth division and competed at several European Championships for Ponies and Juniors. In 2012 she competed at the age of 20 at the Olympic Games in London under the vision of triple Olympic gold-medalist Anky van Grunsven.

In 2024, Barbançon Mestre was shortlisted for the French national team in consideration for the summer Olympic Games. She was later suspended from the team when she failed to comply with France's anti-doping agency to report her whereabouts for out-of-competition drug testing. She claimed the lack of compliance was due to technical issues, but the organization dismissed the appeal and extended her suspension to 18 months.[5]
