Funny, mine is actually about the same as yours. I can get it to drop into the 40s just by lying quietly. I've seen 194 in Spin class once. I thought I was going to pass out for a few seconds there. I'll hit 185 on a steep hill. It generally averages out to be low 160s over the course of a ride, doesn't matter if it's a twenty miler or a century. The doc said that's actually my medium endurance range. Kind of gives me hope that I could complete a double century if I could figure out how to not work so hard and keep it in the long endurance range.
