I am a 35yr old, 5'10", 200lbs, I've been riding a mtb for the past few years, and just recently started riding a road bike('06 Trek 1200), good news is that I have gotten the fit right, no back pain. I do weights twice a week and soccer on sundays.
I ride twice a week with a couple friends and normally the route is about 18 miles averaging around 15mph, we recently did a 45 mile ride averaging 15mph, HR avg 167. My goal is to join a large club ride which is about 50-60 miles and avg speed 19-20mph. I suspect riding in a large group is easier due to draft.
My long range comfort level HR is around 165-170 and I can push to 175 for short periods, but if I cross 180 things shutdown soon after. I suspect 180+ would be my lactate threshold
Am I over/under stressing my HR ? Apart from putting in the miles what can I do to monitor if I am training poorly ?
Unfortunately where I live there are no club rides less than 50-60 miles.
