a plan for running goal

I had a goal of getting back to my 10 minute mile pace for 6 miles. I just managed to do 3 miles in 33 minutes Saturday. I wondered if this was possible and by when. I had no clue in my mind. SOOOO last night I planned it out. I put in saturday as my target day and every week increased speed or distance. It looks like I can make my goal by new years. Heres my plan.

Sep 28 3 mile 33 minutes done
Oct 5 3.5 mile 38 minutes
Oct 12 3.75 mile 39 minutes
oct 26 4.00 mile 42 minutes
Nov 2 4.25 mile 45 minutes
Nov 9 4.5 mile 47 minutes
Nov1 6 5 mile 52 minutes
Nov 23 5.25 mile 54 minutes
Nov 30 5.5 mile 57 minutes
Dec 7 5.75 mile 60 minutes
Dec 14 6.0 miles 62 minutes
Dec 21 6.miles 61 minutes
Dec 28 6.0 miles 60 minutes

Of course this is all negotiable and changeable. I am not sure how I will train in between goal days, but this seems like a doable plan as I used to run faster than this pace when I was slightly younger and much thinner.
What do you thinK.
