Would you agree that sprinting the straights and walking or jogging the corners on a track for 20 minutes is good HIIT. I started this last week as opposed to my normal 3 mile run, and it kicked my butt more than the 3 miles.

22 views so far, and no one can tell me whether or not this is HIIT, and if so is it good, bad, adequate or what?

yeah its fine, just make you reduce your heart rate on the slow sections (ie light jog/walk) and bust a gut on the straights.

Thank you for the response. I just wanted to make sure i was on the right track since this is the first time I've tried HIIT.
