The Moroccan-born Canadian Achraf Tadili ran a very quick finish to win in a record time of 1:45.05, faster than the previous Pan Am Record (1:45.38) set by USA’s Johnny Gray four years earlier in Winnipeg. Brazil’s Osmar dos Santos (1:45.64) could not respond to his rival’s late surge and finished second, ahead of his compatriot Fabiano Peçanha (1:46.39).
