My Commute is not long (Since I am local to nmanhipot one end of Chastain to the other) and my reason was health not wealth. My savings in fuel has easily been offset by clothing and bike swag.
I am not one to make a point to PAY to go to a health club. I am too cheap and I would have a hard time going. Riding gives me a way to HAVE to exercise every day.
I would like to make it a little longer but the road I am riding is by far the safest way between the two points at the times I ride and the only east west corridor in the area that has a Bike lane on it. Still looking for a doable alternate route to add a few miles to the ride home to burn a few more calories. Thought about looping up near nmanhipot's neck of the woods too double the distance. The southbound section would be against the flow so not so bad and the east west would be reasonable either coming up frey to Shiloh rd to booth to bells ferry or out to shallowford cut through Noon day park south or all the way over to Canton then south. Make a dry run this weekend when traffic is light and check it out.
The health benefit has run in directions I never realized. I have managed to drop 33lb since Feb. My over all energy level is WAY up. Still have to watch the calories but it is not as hard to do as when I started and when I do go a little overboard it doesn't seem to be the impact it once had.
I think where I have been really surprised is my stress levels have gone way down. Stuff that would just light me off hardly bother me these days. Those around me notice this as well. Something about the first 30 minutes out of the house getting a good work out really sets the mood for the rest of the day.
