Depends what school you're looking at.
Small D1's usually will take a mile in around ~4:25
Middle Range Schools (I.e. Purdue, North Carolina, Cal) are usually a 4:15-4:10
Big Schools (Oregon, Alabama, Wisconsin) Will typically take nothing less than a 4:08.
You gotta be cookin' if you want them to pay.
OH. you better run those by your junior year BTW. All the scholarships are gone after... probably right around December-February of Senior year.
