Career
He claimed two silver medals each in giant slalom and slalom at the 2009 FIS Snowboarding World Championships in Gangwon, South of Korea, and later represented his nation France in two editions of the Olympic Games (2010 and 2014). Dufour currently trains for Ski Club Sainte-Marie-aux-Mines under his personal coach and mentor Christophe Guinamard. In his official Olympic debut, Dufour recorded a second-fastest time of 1:16.79 in the seeding round of the men"s giant slalom, but shortened his chances of adding another career medal after finishing behind Slovenia"s Rok Flander in a first knockout round by 1.65 seconds.
At the 2014 Winter Olympics in Sochi, Dufour qualified as a lone French athlete for two alpine snowboarding events (including the first ever men"s parallel slalom) by finishing first from the FIS World Cup series in Carezza, Italy and in Sudelfeld, Germany.
In the men"s giant slalom, Dufour could not endure his surprising setback from Vancouver after delivering a fifteenth-fastest total time of 1:39.76 in the seeding run and eventually, finishing beyond a five-second margin behind United States-born Russian snowboarder Vic Wild in the first round.
