Based on research primarily from Peter Larsson’s alltime-athletics, a sub-4 mile has been run on the track in official competition in 40 U.S. states plus 2 territories. In 2 states, a legitimate sub-4 was run on a track, but I cannot find an official result. In one state, it has been done in a certified road race.
Below is what I’ve determined is the fastest mile in each of these states, ordered by time.

Other states
- Drew Hunter ran the first sub-4 mile (3:57) in South Dakota in an unofficial time trial.
- Oliver Hoare ran the first sub-4 mile in Colorado (3:56.8) just ahead of Joe Klecker in 3:58.4 in an unofficial time trial.
- Edward Cheserek (3:53.3) and a few others have broken 4 at the Kalakaua Merrie Mile on the road.
That makes 43 states with a legitimate sub-4 in my view.
The Millennium Mile in New Hampshire has seen a 3:51 mile by Andy Downin, but it is downhill.
Other states without a sub-4 that I know of: Maine, Vermont, Delaware, West Virginia, Wyoming, Nevada
