Those numbers are impressive enough by themselves for a state with just over three million people. (Granted, about two million of them are kids.)
But when you factor in the NCAA altitude conversion, which equates a 16:20.33 in Salt Lake City with a 16:00.00 at sea level, it's downright amazing. This puts 82 kids under the equivalent of 16:00 and 7 under 15:00.
The girls were collectively far less impressive. Only four broke 18:00, and the fastest time, 17:31, would not have been under 17:00 at sea level.
