During the week my riding is usually limited to utilitarian trips because of work (no car, so I ride to work, the store, etc.). On weekends I don't have time to ride for fun as often as I'd like. Lately I've either been doing freelance work or backpacking most weekends.
During my rides I'm limited by asthma that kicks in whenever I ride hard enough to start breathing through my mouth, so I ride at a pretty easy pace.
