I spend 1.5 to 2.5 hours heart rate avg for time is 164 for as long as 2 hours 30 minutes. up to 183 (treadmill on 30 percent grade @ 4 speed to reach 183)for 5 minutes.

I run 3 tmes a week and would advise that you should do not exceed 80% of your maximum HR. To calculate that it is 220-age X .80. Good luck. My direct e-mail address is

I'm sure you can understand that we do not know your health background and cannot suggest that anything is OK. I suggest you go see your doctor to get checked out and then see a local personal trainer for advise.
