Just got back from my route this morning.  I'm still getting used to my HRM.  The target heartrate is higher than on my old one and I'm not sure how to re-set it.  The instructions are no help at all.  For now I will keep the target that's there - 124 but it is kicking my butt.  It started to rain in the last 5 minutes.  They are predicting flurries for this weekend.  Grrrrrr.
