The Cornerman
Once all that is done explain the cornerman (safety ride) system. Start by explaining that the first rider to not follow the system will shout the group the first round at the end of the day, and he will deserve this punishment because he’ll have cost everyone valuable riding time. Use a loud, assertive voice. Be very clear about the importance of the system for a good safe ride.
Explain who the lead rider is, what he’s wearing – show the group his back (this is what they will see on the trail) – and what he’s riding. A bright vest is handy here. Anyone who passes the lead rider shouts everyone at the end of the day. Then do the same intro for the sweep rider. No one rides behind the sweep.
Now for the important bit! The lead rider will place the rider directly behind him at points along the route. These may be at an intersection, a trail hazard such as a hole in a bridge, or at the start of a camping area to slow the group down. The lead should signal to the rider behind him, or in some cases stop and explain what he wants. The lead should always check that the rider behind understands the instruction and has positioned himself accordingly before he rides on. It only takes a couple of seconds but can save time or a life in an emergency.
