Ride with a group.

They'll teach you by talking to you
They'll teach you by you looking at them
They'll teach you how to behave yourself

Basically - you will be able to pick up a bit of fitness and a good spectrum of fitness levels to gauge yourself, and you'll be able to work on your cyclemanship (if that's really a word).
