Billy has always loved any form of sport and notably skiing, when he started at a young age in France during the winters.

Billy loves the training and hard work just as much as the competing and results.

During the 2020-21 season, Billy had two Europa Cup victories, winning him the overall slalom title for the season. In 2022, Billy podiumed twice more in Europa Cup events, finished in 18th position at the Schladming World Cup (ahead of teammate Dave Ryding!) and made his Olympic Games debut in Beijing, CHN.
