Heck, a couple months ago I was damned proud of my ONE mile riding!!
And remember, it's better to not be "perfect" because then you just make everyone else look bad!
Another thing to consider is that if you are out of shape and only riding tiny distances, seeing you biking can be a huge inspiration to other women who are out of shape as well- they will see you pedalling along and hopefully realize biking is something they actually CAN do. Be an inspiration to others!!!
