This is slightly annoying, as I like to track my max HR on each ride.
My question: should I guy a new HR monitor, or will that just be a waste of money? Interested to learn of other people's experiences in this regard. Thanks!
It's a fairly common characteristic when the contacts are dry and you have a jersey that moves around. Options are to ignore the first 15 min of HR recordings, try some gel on the contacts, wear tighter jerseys. This problem is typically worse with low humidity.
