I'm not a distance runner. Were you in full gear, boots, and carrying both your rifle and your pack for that run? My gear, rifle, and pack weighed only about 100 pounds, but the guys in uniform carried 20 pounds more, and those boots aren't made for speed or comfort.
I ran 7 miles in 26 minutes, with incentive (16.15 MPH), but in competition, ran 5K in 28 minutes (6.69 MPH). I was going to do a 40-mile hike as part of a decathlon, this month, but missed the deadline for signing up. My wife says I'm too old for that, anyway, but I'm almost too old to enter.
I don't know what a good 2-mile time is, because we were running 3200 meters as 2 miles; however, I can figure your speed. You ran 2640 meters in 726 seconds. That's 9.91 MPH. Your friend averaged 12.63 MPH.
My math may be in greater error here. I just multiplied the meters for 1 mile by however many miles.
You probably could have run faster before boot camp. The Army took the speed out of everyone I knew. While you're running, it feels as if you're putting a lot of effort into it, but later the numbers don't look so good. Coaches show you segment times where maybe segment 2 or 3 was 2 seconds faster than the previous segment, which means that you weren't trying your best. I am not good at running against the clock--particularly when I'm not having fun. The coach would show that other runners has almost identical segment times. In AAA my junior year, I ran legs 1 and 4 of the 4x400 at one meet, because one of our runners was injured. Everyone agreed beforehand that this would be OK, and the alternative for us was to forfeit. I collapsed after the race, but the coach was pissed at me, because my time on leg 4 was faster not only than my time on leg 1 but also than my 400-meter dash time. We won the event, so I didn't see what the problem was. The unjured runner got credit for my time, but the second place team tried to have our effort disqualified. I know now that I should've been treated after my collapse, but the coach just left me to suffer, at the time. If anyone else has this happen to them, someone should ensure you walk until cool-off, clear your breathing to prevent adema (sp), get a towel to keep you from catching cold, stretch, and get liquids.
It took me a week to recover. I don't know what my time was for leg 4, and it isn't published like times are now. My comment was that I was in front on leg 1, and behind on leg 4, because someone did a poor job of handing off the baton. The coach said I was sandbagging.
By my senior year, my knees were destroyed, but I probably wouldn't have run in college, anyway. They used trickery to make me run in HS, and I no longer enjoyed it. I felt abused and taken advantage of. Running now is painful. I don't have the strength or muscle mass I had then. Also, the speed just isn't there. I get to a certain point, and it's as if I hit a wall. I know I used to run faster. I used to enjoy running, too. It was exhilarating.
