Welcome Catrin; I'm 56 and just ordered my first "serious" bike. Well, for me to plunk down over a grand for a bike, now that's getting serious, lol.
Over the past 6 years I've been riding my old Trek hybrid, that mostly sat in the garage for the first 6 years I owned it. After I went through a divorce, I dusted it off and started riding it, but not very often, or for long rides.
In the past year or so, I've hooked up with a group of lady friends around my age, and we've been going out on 25 to 30 mile rides together. We have a blast. That's when I started wishing for a newer, faster bike. I've been getting more and more into it as time goes on.
Ciao
