Hey Anja, hello from a fellow Anj! (mine is derived from a whole different name, however.)
I highly suggest you go to your local bike shop and test ride as many models in all price ranges that you can. That way, you have a basis from which to start.
My first road bike that I still ride occasionally was a $185 1993 Giant original carbon framed touring bike that was too small for me. I did a lot of miles on that lil bike even though it didn't really fit me right. Sometimes you have to just get on a bike and ride to really know what you want to buy. That bike taught me a couple of things: 1. I needed a larger frame and 2. I needed a different saddle that could support sit bones and 3. Put me in an aggressive position (butt higher than my grips) and I become fearless on downhills.![]()
I am also a runner who ran in high school and is now just getting back into it. I feel for you with your injury.
Good luck and have fun test riding! It's worth it to shop around!
Anj
