The TSD Rally as briefly described in the introduction is the only type of rally which is recognized by JCNA as qualifying for the Rally Program.

In a TSD rally, your vehicle must exactly follow the specified route and maintain the specified Miles Per Hour speeds demanded in the Route Instructions (see Chapter 3) given to you at the start of the rally. The specified MPH speed will change many times during the course of the rally. The navigator must be able to determine if the team is early or late at any location (distance) along the rally route.

This is relatively easy if you remember that:

DISTANCE=TIME X SPEED

Thus: If you have been traveling at 60 MPH (that's a mile per minute) for 60 minutes then your vehicle must have traveled 60 miles!

It is the navigator's job to keep tabs on where the team is in order to keep you on course and on time. That's all there really is to a TSD rally! It boils down to good communications between the driver and navigator. Most importantly, DON'T GET LOST!

An Official Odometer Check (also known as an odometer checkpoint) will be clearly evident to you along the first section or leg of the rally. This will occur at a specified distance stated in the Route Instructions and gives the navigator a chance to determine how your Jaguars odometer reading compares with the "official mileage" as measured by the Rallymaster's odometer used to measure and prepare the Route Instructions.

Along the rally route there will be Checkpoints. Checkpoints may appear at any time or distance. They may be hidden so you may not be aware of them. Checkpoint personnel are equipped to time cars as they arrive or pass by and thus ensure that competitors actually traverse the designated route. Checkpoints are generally of two types, open or closed. An OPEN CHECKPOINT is visible and may require rally cars to stop after crossing the timing line, with the team taking some action specified in the General Instructions. CLOSED CHECKPOINT may be hidden from view. It is one at which you are timed as you drive past without stopping. Do not stop within sight of any checkpoint unless instructed to do so. If you get lost and miss a checkpoint, you haven't lost the rally, just that leg of the rally for which you will receive maximum penalty points. Once again, DON'T GET LOST.
