Rally Maya Mexico, created by Benjamin de la Peña Mora, is one of the most significant international antique car events.
The rally is sanctioned by FIVA (International Federation of Ancestral Vehicles), FIA (International Automobile Federation), OMDAI (Mexican International Motorsport Organization), FMAAC (Mexican Federation of Antique and Collectible Cars), FEDAMAC (Mexican Federation of Motor Racing), and the National Vintage Commission and Porsche Club of Mexico.
It focuses on the historical aspect of motoring in an atmosphere of conviviality in the Yucatán Peninsula. By participating in the rally you will also help the organization to provide medical treatment for children that are wheelchair-bound or suffering from Down's syndrome.
The event is NOT A SPEED CONTEST. Cars must be more than 40 years old and will be classified into categories by age, ranging from 1915-1949, 1950-1969, 1970-1980. In the rally world this type of contest is known as a Time, Speed and Distance (TSD), or Regularity rally, in which the challenge is to cover set distances at an average speed.
There are several variants of such rallies, this will be one of CONSTANT AVERAGE SPEED OVER AN OPEN ROAD, also referred to as a CLASSIC REGULARITY rally. It consists of several regularity or timed stages connected by trunk roads, in which the object is to travel at a constant preset average speed. Although trunk roads are not timed they may transit checkpoints.
CONSTANT AVERAGE SPEED means that throughout clocked sections and as much as possible throughout the event competitors must try to keep the same speed. This important concept is the essence of a TSD or Regularity rally.
COMPETITOR CONTROLLED AVERAGE SPEED: Regularity sections will be determined by the organizer using departure times indicated by the hour, minute and second, calculated using the Route Notebook; no one in the organization will supervise daily departures. From that point on a competitor must maintain an average speed for the entire section. This may sound easy in theory, apparently all you need is a simple formula for distance/time and to adjust your speed accordingly, but in practice things can sometimes become complicated. There are basically two ways of achieving your goal:
- Traditionally, using charts and a chronometer;
- Using an instrument called a "pyramid".
1-. The most popular chart and chronometer method involves preparing a series of charts or lists (spreadsheets) using the average speeds set by the organizer and shown in the contest rules. In this way, for example, we have charts covering average speeds of 35 km/h (22 mi./h), 40 km/h (25 mi./h), 45 km/h (28 mi./h) and 50 km/h (31 mi./h). These tables contain two columns one for distances of 100, 200, 300 and 500 m (63, 126, 189 and 313 yards) as chosen by the competitor; and the other column contains the corresponding time for the average speed shown.
In this way teams are aware of the time allotted for covering any of the distances shown in the chart. Ideally that figure indicates how long it should take to cover a specific distance. Competitors should be equipped with a good distance measuring instrument and chronometer. Distance measuring instruments should be calibrated to match the organizer's device, and the chronometer with the organizer's clock. On timed sections the distance instrument will measure the distance covered and the copilot will watch the time elapsed since departure, calling out the variations in real-time shown by the chart so that the driver can adjust speed accordingly. When the time shown on the chart and the chronometer match the copilot will call out "on average". The amount of difference from average measured when passing a checkpoint will determine the number of penalty points assigned to a vehicle.
2-. How to use a "pyramid": This instrument indicates the theoretic or ideal distance someone will travel at a set average speed. Using this instrument frees the copilot from having to watch the chronometer and read charts, comparing instead the true distance traveled shown on the measuring instrument with the theoretic or ideal distance indicated by a "pyramid". In this case the crucial unit is not time but the distance in meters. The copilot continually calls out the number of more or less meters or "on average" when so.
The following elements are also part of the competition:
1-. RALLY TIME-. The official rally time used for departures and at checkpoints will be displayed by the organizer at the start of the contest so that participants can synchronize their watches. It will be the reference used to determine the number of penalty points assigned to a competitor by the checkpoints, including secret ones and timetables.
2-. DISTANCE CALIBRATION-. Competitors must also synchronize their distance measuring instruments to match measurements shown by the organizer's device. The calibration stretch will be mostly straight and measurements are taken in both directions: going and coming back. The organization will calibrate by travelling the same stretch of road in its own vehicle at a constant speed in the right lane. A team's distance figures must match the organizer's in both directions. Discrepancies can be adjusted using the formulas provided in the device's instructions. Measurement runs may be performed as many times as necessary to obtain the closest match possible.
3-. ROUTE NOTEBOOK-. Provided by the organizer. The route notebook covers the location of self departure points for each regularity section and the mandatory clocking checkpoints. It will also specify the initial starting time and interval between departures, which can be either every minute or every 30 seconds. Based on this information and their Dorsal, competitors can calculate their self departure times for each regularity section and the time at which they should cross checkpoints.
4-. ROAD LOG-. Provided by the organizer, it contains a map of the route showing what junctions should be taken, the starting location and average speed for each regularity section. It uses drawings and symbols, legends as well as total and partial distances to guide the competitors. A table of symbol meanings is included in the log. Suggestion: During difficult stretches, just following the log's instructions to the letter and staying on course will go a long way towards improving your score.
5-. REQUIREMENTS FOR TEAMS -.
A-. EQUIPMENT AND VEHICLE: Competitor vehicles must have valid license plates and registration; third-party liability insurance, on board chronometer or distance measuring instrument such as an aftermarket odometer properly installed; or a Terra Trip or Retro Trip higher-quality instrument (the sensor should be installed on a non-traction or free rolling wheel); or a media Chart Control; Pyramid or Dorsal. The organizer will provide a competitor number that must be affixed to either side of the car, as well as official sponsors advertising decals, which must be visible on the exterior of the vehicle throughout the event.
B-. DRIVER/PILOT-. Although drivers receive most of the glory, he or she must follow the copilot's instructions and drive within legal limits at all times, staying in the same lane without taking shortcuts which would throw off the distance measurements set by the organizer. Drivers should try to steer a trajectory parallel to the center line or shoulder, avoid spinning the tires or doing drifts or similar maneuvers that involve the sensor equipped wheel.
C-. COPILOT-. The copilot is the key element in this rally. He or she has three basic responsibilities:
a). Navigate following the Road Log;
b). Check self departure times and checkpoint times;
c). Make sure checkpoints are crossed on time and that average speed is maintained by giving precise instructions to the pilot; check fluid levels, perform mechanical repairs if possible and assist the driver in general. Unfortunately, copilots will be blamed for a poor showing no matter what the cause.
