Biking is the more elegant of the two choices. When you are riding, you can push yourself to work on your heart rate and endurance, or you can kick back and enjoy the scenery. You can dress like a professional hotshot or like a casual beach bum.
Jogging presents yourself as more than a casual walker. You are out there for exercise and if you're not sweating, breathing hard or running in place while waiting for a light, then you're slacking off.
If jogging is your thing, please act like a civilized human being. Everyday I see people running in the street acting like they are bulletproof from being run over. If you were walking in the street, people would be honking at you or tell you to get on the sidewalk. But put on running apparel and suddenly you're not jaywalking, you're exercising.
