It sounds like "old people trying to train hard' caught up with several of us this past week. After three very good training weeks in the high 40s mpw range I was exhausted most of this week and did 19 miles. I normally sleep about 8-1/2 to 9 hrs. After last Saturday's very good hard run I slept 11 hours Saturday night. My hard 9 miles at 8:31/mi pace was at 141bpm heart rate ave. I got out the door Sunday for a recovery run and my HR was 171 ave. for 6 miles at 9:40 pace. Monday I felt too tired to run and took a rest day. Tuesday I ran a 3.3 mi recovery run at 12:40 pace and HR was 161 ave., and Wednesday I ran the same loop feeling a little better but HR was still 160 at 10:20 pace. I took Thur and Fri off and then ran 9 on Saturday again with my son and daughter-in-law (until they dropped me) at 9:05/mi pace (about :30/mi slower than the prior week and at 155 HR ave.) This morning's run started at 11:30/mi. and HR was at 160 again. I dropped to a walk for the remaining 2 miles and HR was 120 while walking, which is a reasonable recovery level for me. Next week I am going to try to get the mileage back up but at very easy pace level until I feel more fully recovered.

It can't do that. Other things it can't do are pick up HR interference from overhead power lines, and pick up HR interference from someone else's Garmin.
If you find the readings are high at the beginning of a run, it is because you are not warmed up. I used to regard this as a bug, but now I see it as a feature. Go out slow, and stay slow until the HR reading falls to the easy range. Then you can start doing whatever the plan for the day calls for.
Alan,
My HR is usually low at the start of all my runs. Anywhere from about 50-95 depending on my warm up activities. My workout cadence is extremely consistent between 169-171 for steady state runs. What I sometimes observe is that I will be running for a couple of miles at maybe 135-145 HR and HR will suddenly jump to 170 with no change in perceived effort and remain at the level for the remainder of the run. I know I wear my Garmin more loosely than recommended because wearing it tighter is annoying to me. The sudden jump in HR I sometimes see to a number that is identical to my cadence without any noticeable change in perceived effort seems difficult to explain unless the sensor movement on my wrist is being interpreted as HR.
