JC at the Nor-Cal Spyder Rally all group rydes are conducted bu "Trained Road Captains." All Road Captains have gone through a training session so they are aware of the following:
The Route: we require that all routes have been pre-Ryden within the week so that we know about construction and other road conditions before we take a group out on the ryde.
All rydes are led by a trained Road Captain, and there is a trained Road Cpatain serving as a Sweep to assist with any mechanical or physical issues that occur within the group. In most cases these two Road Captains are also in direct communication with each other. With very large groups we split them up and put 4 Road Captains with the groups as lead and sweep.
We always conduct a safety session before before each ryde including the route, the destination, the stops along the way and Turn Signals. When I lead a ryde I signal every turn with turn indicators and hand signals. I comminicate with my sweep to make sure they are seeing all of the signals make it back to the back, and we reinforce the need for this when we have a fuel stop.
We also explain a concept called "bread crumbs". We tell all ryders that if they are with the group and we are making a turn, if they can't see the motorcycle behind them, they should stop at that turn in a safe place where they can be seen by the following members of the group. Our groups never make a turn without leaving this bread crumb behind. It has only rarely been an issue, but is very reassuring if some one has had to fall behind for whatever reason, and we have never lost a Ryder. Of course we discuss proper formation and staggering. On occasion if we have someone who is not conducting themselves in a safe manner we will excuse them from the group. Zero Tolerance for Alcohol on our rydes.
So JC come join us in Nor-Cal so we can compare notes.
