The Tour is designed for those that would rather travel the same route as the Rally but without the pressure of timing and scoring of the Rally.
The Rally is a Time-Speed-Distance (TSD) event that requires that you travel the route at the given speeds, and pass the “checkpoints” on time. You are scored on how closely to the correct time you arrive.
Although vintage rally equipment is allowed, you do not need any special equipment -- only a pencil, paper, a time piece, and a calculator.
The best advice is to stay on course and have fun.
