Repond is together with Lukas Britschgi the first Swiss skater to win a medal (bronze) at the European Championships (in 2023) since Sarah Meier took the title in 2011. Repond was nominated for the ISU Skating Award 2024 in the category "Best Newcomer". Repond followed her two older sisters into the sport and is coached by her sister Jeromie. Her younger sister Caline is a figure skater as well. She missed the first half of the 2025/26 season due to a foot injury and started full training again in December 2026.
