Lacourt collected three gold medal at the European Championships. He became European Champion in the 100 m backstroke (long course) ahead of compatriot Jérémy Stravius in a time of 52.11.[2] This time was a new European record and the second fastest time ever, second to Aaron Peirsol's 51.94 from 2009. He collected the 50 m backstroke title in a time of 24.07, also bumping him up to the second fastest performer of all time in that event. On the final night, he collected gold in the 4 × 100 m medley relay.[3]
Lacourt failed to win any medals at the 2016 Summer Olympics. Following his 5th-place finish in the 100 meter backstroke, Lacourt made international news after criticizing the sport of swimming and making disparaging remarks about Chinese swimmer Sun Yang. In a post-race interview with French radio station RMCsport, Lacourt said: "I am very sad when I see my sport getting like this. I have the impression I am looking at athletics, with two or three doped in each final. I hope that FINA is going to react and stop this massacre, because it is getting sad," and finished with "Sun Yang, he pisses purple!"[4][5] After being defeated by another Chinese swimmer, Xu Jiayu, who won the silver medal in the 100 meter backstroke, Lacourt said, "I don't like being beaten by a Chinese."[6][7]
Lacourt was married to Valérie Bègue, who won Miss France 2008. He is the father of a girl, Jazz, born in October 2012.[citation needed] Lacourt and Bègue divorced in 2016.[9]
