You know, for a 2 mile run in 16 minutes I’m going to disagree with Don’t fight the hypothetical on both the Advil and the GU.
I am not a sports therapist, doctor or competitive runner but I do run regularly, have made noticeable improvements in my mile times and like long distance runs (20+ miles), those are my only credentials…
Anyhow I read in Runner’s World that at one of the recent Western States Endurance runs (100 mile race) a group of doctors studied runners who took ibuprofen (Advil) and compared them to runners who didn’t use the stuff. They found no benefit to taking it before or during running and came out with a recommendation against using it (they did not say anything about taking ibuprofen after the race to deal with muscle inflammation, that was outside of their study). They actually found that the runners taking “vitamin I” were a bit worse off.
I did use to take the stuff before and during my long runs. Can’t say that it did any good and I found that just paying more attention to diet, hydration and sleep the day before and morning of my long runs made for much more improvement in performance and recovery.
For 16 minutes of exercise you don’t need any special foods like GU or other energy gels (I use them myself, but again that’s only for long runs, several hours). Running two miles will burn something like 250 calories, it’s not much. I’d recommend having a decent dinner the night before and a light breakfast (skip the bacon and eggs) and maybe a light snack (something that is easy on your stomach) if you find yourself getting hungry before your run, but “engineered foods”, electrolyte solutions and the like are just overkill for 2 miles.
If you have one week to get to 2 miles in 16 minutes…how fast can you run it right now? If you’re doing 8:20 miles now then you can probably push yourself a bit within a week, however if you can’t break 10 minutes/mile today you’ve got a tough task. I’d say push your pace a little bit, maybe do some interval training (sprint fast for a short distance, then slow to your normal running pace until you have recovered enough to sprint again, repeat). Don’t overdo it and injure yourself by doing tons of running 5 or 6 days in a row!
I’d also recommend running on the same kind of surface you’ll do your test on - running on a treadmill is not the same as running on a track, pavement, etc.
ETA: Just noticed you said that you think you’re close to your goal. Pretend you’ve got the meanest, nastiest DI pacing right behind you shouting threats?
