I love all of the suggestions, also. It is hard to stop feeling guilty, though. One thing, I know is that I am not going to record my miles on Bike Journal next year. I feel too much "virtual" peer pressure from you guys! Not so much in terms of miles, but in speed. So, I will just use my trusty computer and maybe keep a journal. Two years ago I rode 3,000 miles. Last year, I did 2600, but chalked it up to my illness woes in the fall, when I didn't ride much. I set a goal of 2500 this year and I have about 100 miles to go. I know I will make it. But, I am not sure it's realistic for me to set a goal of more than that.
When I started riding, I still was doing step aerobics a couple of times a week. After a couple of years of riding, that stopped. I still go to the gym, but I'm doing stuff in the weight room, elliptical and some spinning when it's really cold out. I am thinking maybe I need to get back to step class because it burns the calories.
Based on my experience with aerobics, etc. I think it's wise to vary what we do. Not just for physical reasons, but for our mental health. I got so burned out on teaching classes, it really ruined it for me. Once I stopped teaching, I was half hearted about participating and I gained 15 pounds. That's when I started riding.
