Can you start your ride an hour before or an hour after their start time so that you are not on the road with the bulk of the cyclists? Can you take a parallel road for any part of the route, even every so often to get you off their route? Can you do your route in the opposite direction?

If you don't pay it is bad form to use any of their services. But there is also the business of you getting in their way. What if there is an accident between you and one of them? What if you swerve and cause an accident? What are the legalities involved in something like that?
