Happy Birthday Kik
and welcome to the world of solo-riding! your LBS is 50 miles away??...sounds like a Perfect excuse for a bike ride to me. Maybe ride there and have Ben come pick you up or vicie versie?? I have the opposite problem of most women, I do Everything alone so the first time I rode in a pack I was very nervous, afraid I would bring someone down or forget to signal something back. Tomorrow will be my first club ride and I'm a tad nervous about that too. I've been working really hard on holding my line(something you don't have to worry about when riding alone!). I was all set to try my first century self-supported last Sat until the winds defeated me.....but there will be other Sats and it will happen when it's right, kinda like your first solo ride! I'm so proud of you and all that you have worked so hard to accomplish in your life, your solo ride is the icing on your cake!!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
