In the upcoming Paris-Madrid Rally there will be some special “jogularity” sections. Jogularity is a rally timing system that was developed by English rallymaster, John Brown, who developed the jogularity system for the “Le Jog” – the Land’s End to John O’Groats classic reliability trial. Jogularity is intended to allow novice competitors without the benefits of accurate rally computers to do regularity rallies reasonably accurately. Also many road rallies in England restrict the use of rally odometers to basic units that do not have average speed calculation capabilities.
Scene From Paris-Madrid 2014 Rally
The basic jogularity system provides the navigator with a Road Book or route card, which contains landmarks and timing information along the desired route. The route instructions will list features along the route, both the total and incremental distances to those features, and the incremental and total run time to these features, based on a timing start of 0:00 from the overall start of the jogularity section.
I have included an example of instructions below for a jogularity section in order to show the information that is provided to the navigator.
Example Of Jogularity Instructions
|Instruction Number||Incremental Distance||Total Distance||Landmark/Instruction||Incremental Time||Total Time||Your Time|
|10||0.45||8.35||Speed Limit 40 Sign on Right||0:32||10:01|
|11||0.67||9.02||Right at Tee||0:48||10:49|
|12||0.38||9.40||Farm Road on Left||0:27||11:16|
The time controls in the jogularity sections, both the Intermediate Time Controls (ITC) including the Trial Finish (FC) control, are timed to the second.
The locations of the Intermediate Time Controls (ITC) are not shown in the road book; however they will be sited at one of the features given in the instructions. No ITCs will be located between instructions. As the car travels down the road, the navigator will provide timing information so that the driver can pace the car so it will pass by a specific feature at the correct time.
When you come to a control go straight in. Stopping before the control will result in a penalty of a minute. The marshal will record the time when you stop at the ITC board (which will be at the marshal’s position) and write this time down on the scorecard. The rally marshal will also initial the score sheet beside the recorded time. If there is another car at the control, stop behind it, the marshal will note the time you arrive and complete your timecard as soon as the first car has left.
When you have been given a time on the score sheet, compare that with the correct time from the Road Book instructions. Verify the correct time and then leave as quickly as possible. The timing to the next ITC to the Finish Control (TF) starts anew from the time entered on the score sheet at the ITC. Therefore time lost sitting at the ITC needs to be made up, so have your score sheet ready to present to the marshal so the marshal can note the time and initial the score sheet.
Determine if you are early, on time, or late at the ITC by comparing the time written for the ITC and the perfect time given in the Route Book or the rally instructions. If you are early or late, you must maintain the same amount early or late at the next control. This might require you to adjust the arrival time at all future controls in this jogularity section. Write these adjusted times down in your route instructions so that you can provide the driver with the proper timing without being confused. With this approach, you do not pay for the same error more than once and the jogularity approach also discourages speeding in subsequent sections to make up for lateness in previous sections.
