What is the fastest time a sixth grade boy has ran a mile?

My son is in 6th grade and ran a 5 minute 24 second mile today.

To the kid who ran a 5:24 in 6th grade, here's some inspiration - Alan Webb (current American record holder in the mile) ran these times:

4th - 7:03, 5th - 6:10, 6th - 5:44, 7th - 5:20, 8th - 4:52, 9th - 4:24, 10th - 4:06, 11th - 4:03, 12th - 3:53 (American high school record).

ya i have no clue, but one of my friends ran a 5:10 when he was in 6th grade
