In the process of trying to find a comfortable sit I've come across many reasons why people don't ride more often or further than they do. Others seem to have no limits.

One person told me they quit altogether except for toying around the neighborhood because they couldn't find a pain free saddle. Another because they don't have a very good place to ride.

Mine are two fold: Discomfort and time. After about 30 miles or so my butt just hurts too much for it to be fun any more. Also, there are only so many hours in the day and I do have other things in my life.

If you have something that limits your cycling what is it? Or, what are they?
