This was the first interval running I've done in a long while. It shows 2 miles in 30 minutes. I did the same thing today in the gym.
Week one of couch to 5k treadmill version. One minute run intervals with 90 second walks. Saturday on the first interval the heart rate went bananas, jumping to over 175 instantly, then gyrating around. It settled down. Saturday all but the last run was at 6 mph. Today I held it to 5.8 mph and my heart rate was in the 140s for the runs, all the way back down to the (one hundred) teens for the walks.
