Good thread. I learned how to ride a bicycle without training wheels when I was 4, and rode various BMX and mountain bikes all through my childhood and always took to it and enjoyed it. I didn't have a bicycle all throughout my teenage and early adult years. About a year ago at age 27 it occurred to me I should get a decent bicycle and start riding for fitness. I bought a Kona hybrid bike with usable components. Like you I started off with 10 mile rides, and then after a couple months it was 20 mile rides and now its 50 mile rides with lots of hill climbing every weekend. I am now at the point of wanting to get a serious road bike and joining local rides and possibly races in the future. I figure I have a chance of meeting new friends to ride with(none of my friends ride).
