Every spring, the boys and girls of Booker T Washington High in Pensacola, FL toe the line for a 400m repeat session unlike any other.

On paper it looks like a normal session - 400m repeats under 80 seconds and you start a new 400 every 3 and a half minutes. The trick is, after every 400 you must down a doughnut.

The record for most dougnuts/laps was set in 2008 by freshmen Peter Fricke. He ate 16 dougnuts.
