I found this list http://www.arrs.net/TR_SSpan.htm that ranks Doug Kurtis number 1 at 36 years 4 days. I ran a sub 3 on Mar 1, 2009 and my first was in an obscure small time race in Whitewater, Wisconsin, where I ran 2:51 on July 4, 1972, so my span is approx. 36 years 8 months. I guess it doesn't count since I can't prove it and the course was probably not certified. Anybody else out there with a comparable streak? I did run 2:38 at NAIA in 1973 so somebody should be able to verify that one.
