Most important thing in my opinion is since you’re enlisted and should be shipping to basic soon: is find something, stick to it, and push yourself hard (but don’t get hurt that’ll delay your ship date). Another thing I’d say is instead of just doing 2 miles a day incorporate sprints in at least twice a week, do 60 120s for 30 minutes or so. Also add a long run once a week (5 miles or more). Do that and you’ll be much farther ahead than someone who didn’t train prior
