For what it is worth... I found it interesting that the top seven runners negative split. There were 15 runners total that negative split. The biggest negative splits came from Colorado: Brent Vaughn (18 seconds) and Dathan Ritzenhein (17 seconds).
Brent Vaughn passed more than half the field (131 runners) between the 3K mark and the finish.
Sean Jefferson, Eric Logsdon, Chris Solinski, Benson Chesang, and also had impressive negative splits of 10 to 14 seconds.
