Bicycling all that distance and going up those hills was intense enough for me.
I applaud and deeply respect what you've done. Do you find that you enjoy exercise more than before?
When class starts up again in late August and I'll have less time again, I'm sure that I'll need to kick up the intensity, although I enjoy bicycling a lot more than running. I'll get free access to the gym, where they have fitness assessments, nutrition assessments, and body fat composition assessments! I can move to doing treadmill work, although I don't see myself enjoying that. They also have various fitness classes, and while that might be more social and fun, I also get self-conscious easily. I was skinny when I was a kid, but never coordinated and hence always picked last for the team... *laughter in the tears*
