Into the regiment? Are we talking ranger now lol?Thats some da_n good cardio: 6 min pace for 15 mile. I remember when I was in, I did 11:40 for my 2 mile and could run forever, but I was a.scrawny little teenager then. 2 years later I was up 20 lbs, and bustin it to stay in the 12:30 range on my 2 mile, and truth be told I still wasn't anything special then (although I sure thought I was since my Push-ups/Sit-ups always put my APFT score as highest in every Unit I was ever in, even at West Point, I was ranked 1st in my year physically (before leaving)....really though it was mostly just muscle memory and technique (starting with Tricep pushups and moving to pecs. When they fatigued).
Now I am about 20-25 lbs even more heavy though, which was partly flab at first, but I've traded most of it in for lean mass now. Still working on getting that cardio back up though, since in SFAS they still grade you on the 17-21 scale no matter how old you are, and I am never satisfied unless I at least exceed the max score....so 13 min. 2 mile (when fatigued not fresh) is my minimum standard. Of course since you said you can do 4 mile at a 6 min. Pace already, youve just bumped up one of my short term.goals ;-p
And yeah, I know getting back in is harder right now (especially into The Regiment), but I have a semi-unique background and solid foundation. I've already talked specifically to a SF recruiter to check feasibility, see if they'd even want me and layed out a game-plan.
Ultimately though, I don't care how hard it is, its where I belong, and I'll get there one way or another. Even if took years and maybe a change of identity or 2. (just kidding on the last part of course....maybe). ;-)
My dad was SF, back in 'Nam, he weighed a whopping 160 at 6'1". (Like 1958 enlistee)
Was strong though, mentally and physically.
Make sure you work Ruck runs (as much as I hate recommending that). They do all of their rucks as runs.
