As a lifelong cyclist, both competitively, and transportation oriented, I still try to find time for #2. Sometimes just walking around, no matter where you are, gives you a different perspective about things. When I'm angry, depressed, what have you, the first thing I do is just put on my running shoes and walk for an hour. I used to try to walk home or to work once a week instead of biking or public transit, just for the experience. It's definitely saved me from myself more than once.
