Canadian teenager Christopher Morales Williams races to world indoor 400m record
The University of Georgia sophomore flew to a time of 44.49 seconds to break the previous mark of 44.57 set by American Kerron Clement in 2005 on the same track.
Morales Williams shaved nearly a second off his previous best time set earlier in the month.
The Canadian from Vaughan, just north of Toronto, missed two years of high school track when schools were shut during the pandemic. He did daily solo long distance runs during that time for training, working up to 12 kilometres.
Morales Williams chose Georgia largely because of coach Caryl Smith Gilbert, who trained fellow Canadian sprinter and Olympic champion Andre De Grasse at USC.
His record is subject to World Athletics' ratification process.
