Watch video highlights of American Athing Mu running to an outstanding time of 50.52 seconds to win the 400m at the Charlie Thomas Invitational in College Station. The time, which is the fastest in the world this year, is pending ratification, but it would break the world U20 indoor record.
The 18-year-old was improving the previous record of 50.82 set by 2012 Olympic champion Sanya Richards-Ross of USA in Fayetteville in 2004.
Mu also shattered the 2011 Bowerman winner Jessica Beard’s 10-year old school record of 50.79, while the time is the No. 4 all-time in American and collegiate history.
“The other day I was sitting in front of her Bowerman poster that listed all of her accomplishments and I thought ‘Wow, she is crazy good.’. It’s really cool to have that record now.” said Mu.
Mu now moves to 20th on the senior world all-time indoor list and fourth on the senior US all-time list.
In recent weeks, the teenager has managed to move up the ranks indoors after producing a North American U20 indoor record of 2:01.07 for 800m last month and followed that performance up one week later with a world-leading 1:25.80 run over 600m.
