Last night was four more miles on the Lower Back Bay. I had some company for a change - my youngest son and my niece joined me. We got a late afternoon start and finished a 2 mile out and back just as it got dark.
I kept the pace slow and steady for the first three miles, but did air things out for the last mile, dropping my pace to 8:04. Statistics for the run - 4.2 miles total, 144 bpm average heart rate (80% MHR). One thing of note - for the past few runs I've been having some trouble with my Garmin HRM. My heart rate would spike for the first few minutes when starting a run. I have a Polar HRM that acts the same way when the battery needs replacing, so I thought that perhaps that was the problem. But, I read a thread on the Runner's World forum that suggested checking to make sure the strap was tight. I checked the strap last night before we started and sure enough, the strap had worked itself loose. I tightened up the strap, and the HRM worked like a charm. I'm glad that solved the problem!
Glenn,
ReplyDeleteI have had the same problem, what I have found is that it is either positioned too high or too low or there is not enough conductive fluid (gel, saliva, water) in contact with the skin.
