Guys when doing your 3miler .... have you tried running it outside like its done @ prmc?? i.e The first 1.5 miles out in 12mins 30 and then the last 1.5 mile best effort ??? At least it'll give youa rough idea of how you'll preform and give you a rough guide on how to work at getting your time better! Throw in some interval/sprint work with your runs, that should help.
