Since I am not working now, I make it a habit to ride to the library, natural food store, bike shop, and to local restaurants for lunch at least once or twice a week. I don't do major grocery shopping on my bike, though. At this time of year, I do visit the local farmers to buy produce while it is fresh.
I also ride to the gym, when I am going to do weights, core, or yoga stuff. Usually, my bike is the only one there. It's about 16 miles round trip, so I count it as a regular ride, and on my heavy hybrid bike, with a pannier.
