Thanks Bike Momma and all....My daughter just convinced me to sign up for a time trial this weekend--45-49 Masters Women. (She is 16 and on a local team with great junior coaching and support.) She assures me that all I have to do is just ride my bike. I am kinda embarrassed to race. I usually just do my best and have never competed sports in my whole life. It's a generational thing, but this is weird. we shall see.
