EIFB (Extreme Interval Fat Burning) Running

Did an extra cardio workout this morning. Was reading Mick's Seattle Racing thread on Beachbody and saw some talk of EIFB (Extreme Interval Fat Burning) running.Since this is my recovery week and today was my X-Stretch day, and I'm planning on a 5k tomorrow, I decided this would be a good day to add in an extra run.

From what I understand, you do this workout first thing in the AM:
0-2 minutes = 5 (level of effort)
2-3 minutes = 6
3-4 minutes = 7
4-5 minutes = 8
5-6 minutes = 9
6-7 minutes = 6
7-8 minutes = 7
8-9 minutes = 8
9-10 minutes = 9
10-11 minutes = 6
11-12 minutes = 7
12-13 minutes = 8
13-14 minutes = 9
14-15 minutes = 6
16-17 minutes = 7
17-18 minutes = 8
18-19 minutes = 9
19-20 minutes = 10
20-22 minutes = 5

I ran on my treadmill and started out at 6.0 MPH (10:00 / mile). I increased by .7 for every level of intensity:
5 = 6.0 MPH = 10:00 minute pace
6 = 6.7 = 8:57
7 = 7.4 = 8:06
8 = 8.1 = 7:24
9 = 8.8 = 6:49
10 = 9.5 = 6:18

It was a good workout in a pretty short amount of time and I was sweating like crazy. I walked to the end of the block and back and then took a cold shower and was barely able to stop sweating.

I think I will add it in a couple times / week during my final phase of P90X which starts next week, not sure what days, probably Monday (rest day) and Friday (yoga day) but I'm not sure.
