Guns,
I have to do the run but my shins hurt quite badly when I run (always have, always will) so I can only get in 4-6 miles per week. To make up for it, in addition to what little running I can do, I try to get in some aerobics and pace myself for 15-20 minutes at the effort level I expect to exert during the run. Then because I'm fat, I'll continue working out for another 20-30 min mixing up sprints and distance stuff so I keep my heart rate at a reasonable level.
I am too heavy to win the BMI lottery so I just have to accept losing points on the waist measurement. Last time I maxed the situps and ran the 1.5 miles in a bit under 13 min, but last time I had 3 straight months where I could build up to the test. And I had an NCO who was also worried about passing so we ran together a couple times each week. This time, I prepped for a month, stopped almost entirely for 6 weeks due to the military exercises, and now I have one month remaining to get ready.
Stupid me, I'm taking leave starting the 5th day of my birth month so I even have to take my test in the first few days of the window. Oh well, I'll probably pass but it's not going to be as easy as it should be. I passed fairly easily last time (as it should be) but I let my work schedule interfere with my workout routine and it's going to kick me in the nuts during the test.
Oh yea, on top of that another disc in my middle back is really bothering me, but if I get it checked out I'll probably lose my flying assignment. So I'm prepping and taking the test with 1 or 2 herniated discs in my back... Fun.
I tell you one thing, it sure makes me a hell of a lot less forgiving when a young troop can't pass... "If a fat crippled 35 year old major can pass, what's YOUR excuse airman?"
