With a time of 4 minutes, 9.541 seconds, he edged out Speedo’s Ryan Lochte, who won the event in London in 2012 and was expected to triumph again this year.
But Kalisz was prepared. Though he is a relative newcomer to the national spotlight, the native of Bel Air, Md., has been training for the past few years under coach Bill Bowman in Baltimore.
Who else trains with Bowman? None other than swimming powerhouse Michael Phelps, who already has two Olympic golds in the 400m IM and was poolside at the trials to cheer on Kalisz.
So far, Kalisz hasn’t yet challenged Phelps’ 400m IM world record (of 4:03:84), but Bowman told reporters at the Trials that the youngster has a lot more speed inside him ready to be unleashed.
