"Butt breaks" are allowed at any time for stoker and captain, and are more frequent on rougher roads and near the end of longer rides. Even on the flats we'll coast and stand for just a couple of seconds without losing too much speed. If we are in a group with riders behind us, we'll signal or call out "slowing", take a quick break and then close any gap that might have occured.
Rest stops are at 20-25 mile intervals on club rides or riding on our own.
We enjoy going to lots of local and regional event rides / rallies put on by various charities, bike clubs and other groups . On these rides we usually try visit every rest stop, even if it's only for a minute. The rest stops are all manned by volunteers, and without them, most of these events could not take place. We do these rides for fun, to meet new friends and for the opportunity to ride in places that we don't get to see every week. It's not a race, so we have no problem sparing an extra minute or two to top off a water bottle and say thank you to the folks that make it all happen.
