That sounds like Dropping the Hammer - which is my favorite interval workout.

It is! I just started doing it back 2 back. Reason being, last year's big race I obviously did not have the endurance. If I do the video twice (less the warm up and cool down) it's about 1:48. My race will take me close to 2.5 hours.

The first time through, I do it as is. The second time through I increase the intensity. For example, during the 3x6 minute intervals, at minute 3, I turn to a really hard gear, hold it for a minute, then go back--like and under/over.
