Interesting. I didn't know that, outside of competition, that people rode in true peloton style on group rides. Sounds scary. I've managed to ride for a bunch of years and have never drafted nor been drafted by anybody. So how do you know when your turn at the front is done? Is there an ettiquete? What if you are strong enough to stay at the chosen pace indefinitely? Especially if you are riding with a slower group? For that matter, how short is too short for a pull?
