Worrying heart rate
Hi I am concerned at HR of upto 240bpm at the start of ride, also very high at beginning of ride this morning, have been riding for a year having given up the fags & booze 18 months ago - I'm 30.
I am using a Garmin edge 500 has always given reasonably sensible feedback in the past data for the two rides should be below if I can post a link
this moring HR of 210 early on in ride
Does anyone have any experience of this - am I about to have a heart attack or do I just need new batteries for the Garmin?
