It's really hard for me to feel like I"m exercising at less than 85% of max. That's a comfortable level for me to sustain over, say, an 8-12 mile run without feeling like my tongue is dragging the ground.

I don't use my HR monitor much because trying to stay UNDER a certain %HR (say, 80%) takes all of the fun out it for me .

I know I'll have to get over this eventually, but...
