Notes
This morning was a horrible run. It felt ok overall but my heart rate was totally erratic. It could be the Polar monitor because I've experienced similar issues in the past. My heart rate limit alarm typically goes off at 1 beat above my max threshold and remains there, even during a walk or trot. Today,I was on pace for a sub 7 minute mile but my zone alarm appeared to freeze at 172. I need to discuss this with polar again. It may be time to finally convert to a garmin.
