Myles Misener-Daley breaks his own Canadian U20 record at Pan Ams

The Hamilton, Ont. native earned silver at the Pan Am Games

Myles Misener-Daley broke his own Canadian U20 400m record only seven weeks after setting it at OFSAA this past June. His 45.62 on Friday earned him a silver medal at the Pan Am U20 Championships and broke his old record of 45.71 by 0.09s. The runner is currently ranked third in the world, according to the IAAF World Rankings.

American Justin Robinson took the race in a 45.04, just shy of his personal best of 44.84. Robinson was a member of the 2018 American silver-medal-winning World Junior 4x400m team.

The Canadian women’s 4x100m team also broke a Canadian record in the final, running a 44.77 to break the previous record, which was held by Crystal Emmanuel, Leah Walkeden, Janelle Bell-Spence and Loudia Laarman.


Misener-Daley is attending UCLA in the fall on a full scholarship. The Hamilton, Ont. native chose UCLA because he felt like it was the perfect place to balance his academic and athletic priorities. He’s had a very successful 2019, winning his second OFSAA triple crown (winning the 100m, 200m and 400m) and then capping it all off with this Pan Am silver medal.

The 400m runner will be running the 200m at the upcoming national track and field championships. He’s seeded second in the race behind Jeremiah Lauzon of Red Deer, Alta.
