But I ran across this snippet on Wikipedia:
"The U.S. does allow dual citizenship and consequently races run by Lagat after May 7, 2004 could have been ratified as American records, since USATF rules only state that an athlete has to be a U.S. citizen competing in a sanctioned competition to be eligible to set a national record. However, at the 2005 USATF annual meeting, his 3:27.40 win in the 1500 meters, on August 6, 2004, in Zurich, was not ratified as an American record."
Has the USATF ever given an official explanation for this not being the record? (Likely was because he ran the 2004 Olympics for Kenya, but that doesn't appear to be an official factor in record ratification).
