Born and raised in Geneva in Switzerland. After completing his studies, Jim consecrated the great majority of his time practicing his sport, hundreds of hours of training spent in sports halls or ice rinks. He participated in 59 races and he’s more than motivated to repeat for a new season. The Ice Cross Downhill sport made its debut in January 2001 in Stockholm. With their ice skates, the athletes hurtle down the icy slopes, strewn with obstacles of all kinds, with the only goal being to be first on the finish line. This sport is a symbiosis between Skicross and ice skating. The races are held throughout Europe and North America.

In 2021, Jim finished second in the Invitational World Final 2020/2021 in Moscow, Russia, thus taking the second place of the 2021 Ice Cross Downhill Championship ranking. In the overall World Ranking Men, Jim holds the 8th place.
