France\'s Olympic gold medallist Camille Muffat set a new world record in the short course women\'s 800m freestyle event at the French championships on Friday. Muffat timed 8min 01.06sec, smashing the previous mark of 8:04.53 set by Italian Alessia Filippi in Rijeka, Croatia, in December 2008, a time before the ban on high-tech polyurethane swimsuits. \"My best time over the distance was 8:23,\" Muffat said. \"Fabrice (Pellerin, her coach) threw down the gauntlet and told me I could do 8.04. I couldn\'t duck that!\" At the London Games this summer, the 23-year-old Muffat claimed gold in the 400m individual freestyle with a new Olympic record, as well as silver in the 200m freestyle and a bronze as part of the 4x200m freestyle team. Her new world record follows that by her training partner Yannick Agnel in the men\'s 400m freestyle on Thursday.
