five 2x1 fast intervals with slow jogging rest in between

Began the intervals with a 5 minute warm-up (9:56 ppm) followed immediately by the first fast 2 minutes then a 1 minute jogging rest. Repeated the 2x1 five times. Total time, including warm-up was 20:02 (9:21 ppm). Fast intervals' ppms got progressively slower: 8:03; 8:30; 8:42; 8:49; and 8:56. However, I'm happy that all five were under 9:00 ppm. Jogging rest in between varied from a high of 10:57 ppm to a low of 10:15 ppm (last one). This was a good workout.
