Erratic Heart Rate

What : Easy Run
Distance : 5.16
Time : 46:15

I had meetings either side of lunchtime today, so I didn't think I was going to be able to get out. Luckily the morning meeting finished early so I managed to get out for a gentle run before tomorrows longish steady run.

One thing I have been noticing for a while is that I have a very erratic Heart Rate when I first start running. My average HR for the first mile was 158 and it had a maximum of 192!!! The 2nd mile was only 137, the run average was 143. I had even been trotting for a couple of minutes before I started any stopwatch. I've no other signs of been unwell, no dizziness or shortness of breath, just an HRM saying I've got a ridiculously high HR.

I'm inclined to believe that it is the chest strap having difficulties picking up the electrical impulses early on in a run, maybe I'll have a prowl round the net to see if anyone else has similar experiences.

Here's the breakdown

Mile	1	2	3	4	5	5.16	Ave
Time	9:02	8:56	8:59	8:55	9:01	1:20	8:58
HR	158	137	141	138	140	146	143
