Ok, I'll try to give the actual bpm. I use my heart rate monitor to display the time of activity and then it only shows it as a percent. My max heart rate is set at 210. So between 190 and 210 should be between 90 and 100%. So i guess that would mean it was between 195 and 207. I did have to slow down a few times and even stopped a couple of times and set even though we were supposed to be standing. To try to get my heart rate below 90% or close to it. And yes it really was that high for 20min. Does this mean that maybe my max heart rate is higher then I think? Also have sustained 200bpm for three miles. After which I slowed down for fear my heart would give out not because I had to, ok the feeling of wanting to throw up helped, felt the same way last night.
