To go from a 10 min mile to 8 is totally doable. Running consistently as others have said makes a big difference. Running a lot in one month while letting other things go on a once a week schedule is a good idea, just to get enough repetition in to really engrain the mechanics of running. On that note, having a running analysis with suggestions for drills and strength exercises to improve form is also really helpful.

Glad to see you still Tri'ing V.
