This afternoon I rode my bike to Jazzercise. To drive my truck there, it's a four and a half mile trip that takes 15 minutes on a good day. To ride my bike there off road, it's a two and a half mile trip that takes 15 minutes any day.
By truck, I have to mix in rush hour traffic. Ugh. By bike, I ride through a park most of the way, and have little interface with cars.
By truck, I don't have to sweat on the way to work out. By bike, I have to ride uphill about 70% of the way there.
On the way home, by truck, I mix with Northern Virginia drivers again. Yuck. On the way home, by bike, I ride 70% downhill including mountain bike singletrack through the woods
I wish I could get my lazy self to ride my bike there more often. I definitely will enjoy saving gas money doing it that way, and I could afford to spend the extra calories.
