re: Official Running Log/Marathon Training Thread

There are a few explanations for that, Tornado. It’s probably a combination of things. Do you know what your max HR is, or do you use the estimate method? I figured that you were running your easy runs too fast just based on your running history and your average pace for your runs. That is probably true to an extent. Lastly, if you really were running essentially 5 4-8 miles tempo runs per week, your body was never fully recovering from the bulk of your workouts. All of those things could lead to elevated HRs. I think it’s a very good thing that you are figuring this out right now early in your training.

This can also result from atrial fibrillation. The other things are more likely the culprit, but it might be good to get an EKG when you can just to be sure, especially if you are over 30 and heart issues run on your family. I know runners who have discovered atrial fib accidentally by observing chronically high avg HR. They asked their doctor about it and got an EKG that indicated A Fib.
