You can expect alot of BS. I was 31 with 12 years in. It's just putting up with it and taking it day by day. Go to medical before you get there and get a prescription for the motrin 800. The prescription will make it legal and you will be able to keep it in your locker. I used it the whole way through and it saved my knees. The runs aren't that bad, I never dropped out and I am slow. Just keep running and don't give up, even if you are going slow. Make them put you in the van. I never broke the 10:30 mark and never got broke down too bad at the end when they mash the slow ones. Whenever Gunny Murphy would see me getting beat for coming in after 10:30, she would pull me out cause she knew I was older and within my out PFA standards. Don't sweat it, just do your best and play the game. Oh by the way, the punishment for dropping out of a run in my class was a counseling and a special one on one PT session with gunny at her convenience. Same thing with not passing the weekly PFA at out PFA standards. You got counseled and put on her **** list. Nothing ever really happened with the counselings, they just go in your record. Didn't effect class placement very much. Have fun and good luck.
