According to the best of my knowledge this is the sub 2:10:00 Record Legal Marathon List (Boston and old NY ineligible):
1. 2:05:38 Chicago Khalid Khannouchi
2. 2:06:17 London Ryan Hall
3. 2:07:47 Chicago Dathan Ritzenden
4. 2:08:56 Chicago Abdi Abdirahman
5. 2:09:08 Houston Meb Keflezighi
6. 2:09:32 Chicago David Morris
7. 2:09:35 Chicago Jerry Lawson
8. 2:09:41 Chicago Alan Culpepper
Notes: Mbarak Hussein's 2:09:55 in 2004 was run while a US citizen, but he began representing the USA in 2007. Also, Salazar's 2:09:21 from Fukuoka is also disputed because of the lack of evidence, also leaving him off the list. Am I forgetting anyone, or is this the correct list? Please comment because there are no sources online which properly list this.
