Modified P90x Workout to meet my needs?

Hi Guys.

I have finished week 7 of P90X. I find it quite boring. Mainly because I like running and have always loved doing HIIT on my treadmill or outside when the weather is nice. I have a 1K track around the block from me that I love to use when the snow is gone.

I have different goals than what P90X offers. I want to drop more pounds instead of what P90X is doing. I prefer mostly cardio but I do like tightening up some of the main muscles. I created my own schedule with some of the P90X videos. What do you guys think of this?

HIIT 10-12 intervals - 30s run @ 90% intensity then 45s walk/jog.
