Mile run - how much time can I drop in a month?

[StaticShock]

Three weeks of doing interval workouts with 200s, 400s, and 800s 2 or 3 times a week. On the off days jog or do nothing at all.

The workouts could be 6-8X200, 4-6X400, or 2-4X800. Rest between intervals by jogging the length of the interval you just ran.

Use the last week to rest before your max effort. Stick to easy runs and light strides that week 3 or 4 times. Take off the other days.

As far as doing your final time trial try to find someone to run with who is faster than you.

You could probably get to 6:45-7:00 in a month. A rabbitt during your final time trial will really help too.
