Mosyosalyangoz There are almost weekly "Weekend Ride Report" threads in the Road subforum - that's a great place to get started sharing your rides, if you're a road cyclist. Long-distance has an annual thread for sharing centuries (100+ mile, or 161+ km rides).

If you want to make friends on Strava, I'd start by joining some clubs. You may even have some reasonably local Strava clubs that will allow you to connect with other riders in your region.
