I bike to work. Only 2.25 miles one way. Once or twice a week I stop by the grocery store/post office which bumps my daily mileage to 5 to 9 miles on those days. In general it helps to wake me up in the morning, puts me in a good mood, and helps me stay in shape. It took a lot of time to make it a routine. I've been doing it for almost two and a half years, and it took me close to two years before I actually started looking towards the bike ride in the morning. Before that I often had to make myself do it. I knew that it was good for my health, and I knew I would feel good afterwards, but my mind would still try and play tricks to try and take the car instead of bike. Crazy how mind works, and crazy how long it took to break the "I'm not looking forward to this bike ride even though I really am" mindset.
