I haven't been on many group rides and the few I have I always just go with the flow and try to look out for everyone around me, but I had a conversation with a guy yesterday that raised some questions. If the lead rider is going slower that you would like is it ok to pass them and take off on your own to the nominated destination via your own route without telling anyone before hand? Is this better than being the guy riding "sweep" or "tail end charlie" deciding to bugger off on their own or worse? Is it the same as just peeling off from the group without notice because you want to travel a different route? Are these things considered "ok", or "dick moves" and likely to make a guy unwelcome on future rides?
