Not saying that someone couldn’t do that in a PT test but more often than not, people aren’t training to the level they’d achieve that. If they were running distance in high school, sure. It’s an ordinary time for a high school varsity cross country runner.
shrug I think 6:00/mi for 3 miles is very achievable for a normally athletic male who practices running a small amount.
(Just went back to my logs: when I picked up running at age 34, it took me four months of running ~4 days a week to run a 5k at <6:00/mi. I say this not to brag, but to say that it's a pretty pedestrian time, especially for a young presumably fit marine)
