OK, this resonated with me. I FREQUENTLY debate going on a bike ride... but don't have enough time to make it a "good one" or have an appointment or something that MAY (or may not) interfere... 2 weeks later I haven't ridden a mile.

I have never regretted going for a 8 mile bike ride around the neighborhood. 30 min or so + time to get suited up and pump up the tired. Every little ride counts. Matter of fact, I find that I'm usually in better bike riding shape when i do frequent short rides rather than really long rides that leave me exhausted and wiped out for days.

So the trick is just to get started. At least put your stuff on and go pump up the tires. By then, you'll probably want to go for a short ride. The hard part is just getting started, for most of us.
