Times from last year count right? So we've got:
Lagat - 12:59
Teg - 13:04
Goucher - 13:10
Fam - 13:11
Ritz - 13:16
Abdi - 13:18
Kirkpatrick - 13:19
Moran - 13:20
McDougal - 13:20
With the amount of racing left this year there's still a handful of guys who could run under 13:21 (Solinsky, Dobson, Lincoln, Rohatinsky, Rupp, etc).
Compaired to where the US was even 3 years ago, some HUGE strides have been made.
