Article 8 : At the start, each rider will receive a brevet card and a cue sheet indicating the route and the location of the checkpoints. Riders must stay on the route. If a rider leaves the route, they must return to the route at the same point prior to continuing, ie. no shortcuts or detours from the route, unless specified by the organizer. Riders must stop at each checkpoint to have their card stamped. Organizers may also include unannounced checkpoints along the route. This assures that everyone will stay on the prescribed route.
And so I got a stamp! It is a Trodat Printy 46119 with my name, RUSA number, and the date. I had hoped to have it in time for the Volcanic Arc 1000K, but it just arrived today. Looking forward to using it at a staffed control some time soon.
I also inherited a 100KM permanent route (#2337 Running of the Bulls) which I rode for the first time this Sunday. Sending my card and proofs of passage to The Permanista.
