Spain’s Mireia Belmonte today managed to break the women’s short course meter world record in the 400 meter freestyle also, clocking 3:54.52 at the FINA 2013 World Cup meet in Berlin, Germany where Camille Muffat’s world record from the Chartres Europeans in November 2012 was 3:54.85. That is two world records in two days, both the 400 and the 800 freestyle. See the result list here.
