I'm not sure how they're doing it now but there was no PT on Thurs, or Sun. Mon, and Fri, were formation runs, usually around three miles and Sat, was the Battalion run out to the lighthouse and back, around 5 miles. The pace is slow but it's long. The shorter runs went a lot faster. I remember the hardest run I ever had was a real fast pace (mind you I was no great runner) but we did the 3 mile variety, lost a ton of people, and our DI actually gave us a Hoo-rah when we were done after checking his watch. Even he was a little out of breath. On Tues. you may have individual timed runs, usually 2-3 miles and on Wed. is the mock-PFA. You're scores don't count but believe me they are looked at, posted too. If you do fail (less than 10:30 run) you will get immediate special attention at the finish line. If your run times aren't great the individual runs are your best chance to improve because the formation run's don't help as much I think. You have to really push yourself to get your times down. As for falling out, never good. If you fall behind but catch up before the run ends, or fall to the back of the group it's usually no big deal, as long as you put out the effort to finish. If you quit and jump in the van, DI's will be waiting for you when it stops. It gets ugly from there.
