Hi, I have been using my Garmin Forerunner 210 week in week out since about June. It has worked faultlessly. However, for the last 10 days I have noticed that it shows a VERY big spike in my heart rate at the beginning of my run. During this part of my run I am not working very hard and am not out of breath at all. In fact I am just getting going and I am careful not to start fast.
On my last run I thought it might be poor contact with the strap so I made a specific effort to wet the contact area with saliva before I set off. It still happened.
You can see some screen shots of my heart rate since this started happening here:
Any ideas what is wrong and I how I can fix it? Really annoying as I am sure it is throwing the calories burned figure to a higher number than it should be.
