An "AK run" seems to be a typo or shorthand, but if you meant a "5K run," it is a race distance of 5 kilometers, which equals approximately 3.1 miles
. This distance is popular for runners of all levels and is equivalent to about 12.5 laps around a standard 400-meter track or 5,000 meters in total
. If you meant something else by "AK run," please clarify. Otherwise, a 5K run is 3.1 miles long.
