Give the guy some slack. 13:10 in his first 5k race of his first pro outdoor season. He far ahead of where his other white counterparts were during their progression to sub 13.
Here is the progression of Solinsky prior to his 12:56:
2009 13:18.41
2008 13:18.51
2007 13:12.24
2006 13:27.94
2005 13:37.55
Here is the progression of Tegenkamp prior to his 12:58:
2008 13:25.71
2007 13:07.41
2006 13:04.90
2005 13:25.36
2004 13:30.90
Here is the progression of Buster prior to his 12:55:
2003 13:17.81
2002 13:12.04
2001 13:23.94
2000 13:26.20
Here is the progression of Baumann before his 12:54:
1996 13:08.81
1995 13:01.72
1994 13:12.47
1992 13:09.03
1991 13:28.67
13:00 is still hard to break for non-Africans. You need to give him time to get used to these paces - perhaps for a few years - before he has his breakthrough. None of our sub 13 Americans did it overnight.
