So I'm looking to improve my 1.5 mile run time for a PT test. The fastest I've ever run is about 10:30, however that was back in 2011.

Im considering a high intensity interval approach with a 1:1 rest to work ratio. Like 300m, 200m, and 100m sprints with rest time equaling my 300m run time. Over time increasing the overall distances (increasing the interval amount, not lengths), and decreasing the rest time. I have a few months to work with before testing.


Or should I just be running two miles a day and trying to decrease run time?


First hand advice is welcome.
