I'm not sure if you're saying this as somebody who never runs, or somebody who runs so often that you've forgotten baseline levels. That's a very significant hurdle for most people. I'm in very good shape strength wise, but I'd almost certainly need to do some significant training to meet that since I just never run.

That's about a 8:30 mile scaling for the fact that its harder when you have to cover more distance... seems pretty reasonable to me as a fitness baseline for the army. I would struggle to make that now but if I had one month to prep I could clear that

I don’t think someone completely untrained can do 10’ / mile.

A 29 minute 5K is not trivial
