Welcome! Welcome!
Sounds like you are doing great with your new cycling adventures. I know it takes some getting used to venturing out in the "real world" and clipping in and all. I'm pretty new too. Lucky for me, I have a cycling freak husband to show me the ropes. Regarding cadence, he encourages me to stay somewhere between 80 and 90. I find myself in the 75 range a lot because it seems to feel right, but somewhere in the 80's is starting to feel better depending on the terrain and how warmed up I am, etc.
I know what you mean about wanting to be able to be fast enough to hang with other people. I'm righ there with you. Speed comes in time. The more you ride, the better you'll get. If you have trained to run faster, you'll find it's similar with cycling. Shorter "speed" rides and longer "endurance" rides that you pace yourself on, etc. You'll find threads about it if you search or start a new one if you want.
Congrats on your new passion! I completely agree that running is so way better than cycling, which is why I officially "retired" from running.![]()
