Will this training plan get my mile from 5:47 to 5:00?

It's hard to tell without more information on your background as a runner.

In general, I'd recommend running twice a day as often as possible. The more running you do the better. 47 seconds is a lot in a mile.

Yeah, that's way too many days off and a reliance on workouts instead of actual running ability. I, too, recommend doubling. You'll improve efficiency in a hurry without too many runs being that hard on you.

What makes me almost think you're trolling us is that you said this is your endurance base plan, yet you're barely running on 3 of the days per each week.

If you doubled and did strides you would probably improve faster than doing these workouts off hardly any mileage. If you're building base, then you just want red blood cells and basic speed. Sharpening off of little mileage won't yield much of an improvement. The #1 way to improve is to put in a steadily progressive aerobic effort for three straight months. You'll have a whole new set of better red blood cells.

Do you have a link to a training plan that'll drastically improve my mile time in 5 months? I found this plan on the Internet and was told it was good.

yeah, google summer of malmo

Seriously go check out sweat mobile on the App Store. Can see a lot of different peoples training on there

I would dump the schedule and lengthen the base phase to 10-12 weeks, the latter is better. In your schedule is too little easy basic volume and too much intensity, and probably rest days too.

Typical milers weekly schedule is not very much different than 5-10k runners in the base phase. There is lots of better schedules in the internet which you could follow, if not doing it by feel. Just run enough, throw in weekly short hills fast to keep your speed up until it´s time to get ready for racing. SOM is much better "schedule" in my opinion.

20-60 minutes is a ridiculous range of time for all your easy days. Knowing absolutely nothing about you, I would say just get out the door and run 6-7 days a week. Run an hour easy days and 70-90 minute long runs once a week. With that alone you should be able to PR by a good bit. Then introduce workouts.
