Born in Chamonix in 1982, Aurélien Ducroz first made his name as a top-level skier: junior French ski-jumping team, then freeride. He won the Xtreme de Verbier several times and became freeride world champion in 2009, a title he took again in 2011.
Alongside, he moved into sailing: Mini 6.50 in 2010 and 2011, the Tour de France à la voile in 2015 and 2016, then the Transat Jacques Vabre in Class40 (4th in 2013 with Yannick Bestaven) and in IMOCA in 2017 with Romain Attanasio.
In Class40 he raced with Louis Duc on boat no. 150 in 2019 (5th in the Transat Jacques Vabre), then from 2021 sailed no. 166 in Crosscall colours. He was Class40 world champion in 2022 and won the Massilia Cup Offshore in 2025.
