Training Schedule Opinions

Id eventually like to run 5 - 6 minute miles, for miles.

Which training schedule works better for this?

1:

Running 800m per day at 5 minute mile pace one week, next week running 1000m at 5 minute mile pace etc

2:

Running 200x5, 400x2 per day one week, 200x7, 400x3 next week etc (at 5 minute mile pace)

Looking for suggestions and advice, thank you for your time.
