Just got back. Didn't finish the full repeat 9 times. Yes, I was mistaken, it wasn't 7 times, it was 9. I started into my 7th repetition. Didn't finish. I didn't quit. It is wicked hot out. I was starting to get dizzy. I was drinking water. Also had some gu to help with energy. When the dizzy first started I walked it off and started to run again. It came back almost immediately. Heart rate was spiking high too. That was it for me.
Turned off the music and walked the mile back home.
Still counting it as a success today. I covered 5miles, and burned 818 calories. Not bad for just over an hour of a workout.
