Faster 5K: The whole program

I took a few minutes to plan out my entire Faster 5K program.  It's based solely on the Couch to 5K program.  I started with much higher mileage than C25K did because at this point I have a pretty solid base and am running 3+ miles easily and regularly.  For instance, week one jumped straight into at a total of 37.5 minutes per run.  It works up to 40 minutes, and I let it stall out there because I don't see myself wanting to run for longer than 40 minutes on a regular basis and that's about all the time I have in the morning unless I start getting up even earlier.  I just don't see that happening.  Basically, it's a 6 week program.  C25K is 9 weeks because you spend the last 3 building up to increased time and distance with each run.  Since this is aimed at improving 5K times and not on increasing time and distance, I just left it at 6 weeks, at which point I hope to be running 10 minute miles regularly and finishing a 5K in 30ish minutes. 

I've not done it, so I don't know how it is going to work out, but this is what I'm shooting for right now:

Week 1: 15 reps of: Run 10 minute pace for 1 minute, run 12 minute pace for 1:30
Week 2: 11 reps of: Run 10 minute pace for 1:30, run 12 minute pace for 2
Week 3: 4.5 reps of: Run 10 minute pace for 1:30, run 12 minute pace for 1:30 then run 10 minute pace for 3:00, run 12 minute pace for 3:00 (to keep this workout within 40 minutes this ends on the 5th rep of 1:30 runs)
Week 4: 3.25 reps of: Run 10 minute pace 3:00, run 12 minute pace 1:30, run 10 minute pace 5:00, run 12 minute pace 2:30. (to keep workout under 40 minutes, it ends on the 4th rep of 3:00 at 10:00/mile)
Week 5, Day 1: 5 reps of: Run 10 minute pace 5:00, run 12 minute pace 3:00
Week 5, Day 2: 3 reps of Run 10 minute pace 8:00, run 12 minute pace 5:00
Week 5, Day 3: Run 10 minute pace 40 minutes
Week 6, Day 1: 2 reps of: Run 10 minute pace 8:00, run 12 minute pace 3:00, Run 10 minute pace 5:00, run 12 minute pace 3:00
Week 6, Day 2: 3 reps of: Run 10 minute pace 10:00, run 12 minute pace 3:00
Week 6, Day 3: Run 10 minute pace 40 minutes

Theoretically, I believe I could replace the slow and fast run times with anything as long as they were reasonably close and ultimately improve my pace.  Hopefully, if this works, I can use it again to get from 10 to 9.  I'd be pretty excited to do a 5K in less than 30 minutes.  From there, I don't know if I'll be looking to improve much more, but I am very competitive, especially with myself, so I'll just wait and see.
