Weird run today! After Saturday's run we took it easy and ran 8.4 miles at about a 9:17 minute pace. My heart rate is usually about 135 for those runs. But today it was around 170! It started in the 140's for the first couple of miles, then the 160's then the 170's! My maximum is around 185, and my heart rate actually got to 179--going slow!!! I can usually never get it up that high--the whole time I've had my Garmin with the heart rate monitor (about a year), it's only gotten that high once before.
But as soon as I stopped running it dropped to 114 within seconds (it seemed, anyway), then to the 90's. My resting heart rate is somewhere around 55 and usually during the day it is around 75. So I don't know if I should take tomorrow off, maybe I am overtraining? |
