I finished with an extra 5 min or so cool down and an extra few minutes of stretching. I kept my heart rate in the zone 3-4 range, dropping down into the high 140s during the recovery intervals and getting up into the low 160s during the climbs. On the speed intervals, I went between 4.3mph and 3.7mph; on the climb intervals I stayed at 3.7 on the recovery and worked between 3.4 and 3.7 mph on the climb segments. I felt pretty good after class. Sweaty, but not dead tired.
