Ok so today was my first ever ride with my first ever Heart rate moniter (which I got for christmas). It worked perfectly, but I am wondering If i have got it set correctly. I set it for my age (46) and it automatically gave me the lower and upper levels for a fat burning programme of 113 and 96 bpm. I set off and did my usual 25 miles. But I found it impossible to ride as slowly as the moniter was telling me to (to fit in the range). I was happy at between 130-145 bpm and completed the ride without getting out of puff at all. The alarm was going off throughout the ride telling me to slow down/reduce the bpm. I was riding at around 75-80% of my max bpm roughly. Anyway my questions are: 1) Do i really need to ride at such a slow rate to stay in the fat burn zone? 2) am I actually fitter than I think? 3) should I set the moniter to a lower age maybe? I thought that riding at a pace which exerts you but doesnt see you getting out of breath was the optimum fat burning pace(ish)...which was what i was doing...but the moniter thought I was doing too much. I want to burn fat primarily. On todays ride I really felt that the moniter was underestimating my 'ability'... ...any thoughts ?
