i am in Honor Class 21-02 right now, and we graduate Friday, the 21st. as for the running, it varies greatly. most weeks, you will run 4-5 days a week. there are formation runs, individual runs, PFA runs, etc.... If you get injured or get shin splints, then you should go to medical. do not put it off because as other people on this board have said, it just leads to worse problems. Ignoring things like that will keep you here much longer than the ideal 13 weeks that you are supposed to be here. always ask for ice too. ice will help a lot of problems.
i was a runner before i came to OCS, so i haven't had much of a problem with the running. actually, if anything, i would say i've gotten out of shape since i've been here compared to the shape i was in before i arrived.
take care
Matt L.
