Fortunately, my wife just got her first real road bike and she is really passionate about riding so it's nice to have a hobby we both can do together. We even bought matching mountain bikes.
We're taking a big group up to Lake Lanier this Sunday to practice on the course for the Irongirl. Are you doing that?
