are you doing the full Insanity program? or was this your "sprint" day for the week?
i thought about doing that very same program for my "once in a blue moon crazy amount of cardio" but then thought that even at that rate that i would be crazy doing that much cardio
basically, i talked myself out of it because i thought it was more cardio than what primal exercise called for
