Class 1
Boys
No Class 1 athlete has ran within 45 seconds of Caleb Hoover's lifetime best 15:00.60 and only two have ran within a minute. His 15:00.60 at 2010's Missouri Southern Stampede is the seventh fastest performance in state history. His 16:11.11 at Oak Hills in 2010 is the Class 1 state record, 11 seconds ahead of his 2009 performance, and 22 seconds ahead of the next closest mark.
