I don't know if i qualify as "senior." I'm 49,and I just had to arrange for babysitting for my granddaughter so i can go riding this Sunday AM as she is sleeping over Sat night and will still be here until late AM. I don't know any women my age who enjoy riding, but everyone who I've ridden with has been kind and encouraging to me. People at work think I'm crazed ( and don't hesitate to rag on me) because of the way i eat and the things i do, but their idea of fun is my idea of boredom. I figure I have to live in my skin. as for the nervousness, just take your time and do what you enjoy. Yesterday I was flying down a muddy bumpy hill standing on the pedals and loving it. In the start of the summer it was freaky for me to go fast down a small bridge along a road. Just gradually confidence increases. I don't worry about fast, I'm only riding for enjoyment. there is a bike club here that has easy or "fun and fit rides." They are good for laid back days and sight seeing. It's excellent to know that there are other women around who are over 40. Maybe you could ride with slower partners or off road or on country roads once in a while too. Kathy
