how many miles, or what events must one participate in before you can call yourself a cyclist.
It's not a question of miles or events. It's a question of regularity. If you ride regularly, say a few times a week at least, call yourself a cyclist. If you ride only every now and then, say a few times a year, you're not a cyclist.
You don't have to ride a century or participate in races or charity rides to call yourself a cyclist. But if you want to be honest about it, especially when you describe yourself to people, don't call yourself a cyclist unless you have made cycling a regular part of your daily or weekly routine.
I bought my first road bike in 1985 (KHS Gran Sport with Suntour components), but I didn't ride it regularly until 20 years later. Sure, I rode once in a while, but not to a degree worth mentioning. It was just something I owned in case I needed it, but I never needed it. In all that time, I never thought of myself as a cyclist, in the same way that today I no longer think of myself as a photographer, although I once earned my wage as a photographer, and I still own and occasionally use my camera gear.
If you're riding a bike, people who see you can certainly describe you as a cyclist (a la Hyacinth Bucket -- "Mind the cyclist, Richard"), but don't call yourself one unless you ride regularly.
