Rally Maya Mexico now in its fourth running was created by Benjamin de la Peña Mora, a respected Notary and classic car collector in Cancun. The rally is considered a major international classic car event with international competitors. It draws historical car collectors together in a genial atmosphere of hospitality and comradeship in southeastern Mexico. The event is recognized by the Mexican Federation of Classic and Collectible Cars (FMACC), National VINTAGE Commission, Mercedes-Benz Club of Mexico, International Federation of Historic Vehicles (FIVA), Southeast Car Museum and the Pan-American Race Image Museum,.


The rally also supports medical treatment for children suffering from type I diabetes, hearing problems, children requiring wheelchairs. Its sponsorship of hysterectomy awareness and research programs provide accurate and reliable information on this medical procedure.


This is NOT A SPEED RALLY, the only general condition is that participating cars be more than 40 years old, divided into categories from 1915-1931, 1932-1948, 1949-1960, 1961-1975. This type of race is known as a Speed, Time, Distance, or Regularity event and focuses on maintaining an average speed over a set distance and route. There are several versions of this race, in this variety the aim is to maintain CONSTANT AVERAGE SPEED ON AN OPEN ROAD, it is also known as a CLASSIC REGULARITY event. A single competition can have several sections in which time and speed are officially monitored for constant speed over specific distances. The official route sections are connected by segments in which no official monitoring is performed but in which time and passage are recorded.


AVERAGE SPEED, refers to the speed maintained throughout a monitored section of the route, the object here is to sustain that average as much as possible. This is an important concept to grasp since it is the essence of such races.


AVERAGE SPEED CONTROL BY THE CONTESTANT. Regularity sections begin at points set by the event organizer. Normally and as is the case in this event it will be controlled using a system in which cars start different sections at a specific hour, minute and second indicated in each competitor’s road log, without any departure supervision by organizers. Teams must maintain an average speed throughout that section. Theoretically the system is simple and success can be achieved by using a simple formula of distance over time, then adjusting the speed. In practice however, things become more complicated and your average speed becomes a factor controlled in two ways:


  1. Three traditional system of tables and chronometer.
  2. Use of an instrument called pyramid.


1-. There is a variety of table and chronometer systems but the most popular requires prerace planning of tables or lists (spreadsheets) for the different average speeds required during the race (as set by the event organizers in the Rules). For example, there will be an average speed table for 35, another for 40, one for 45 or 49.9 km/h.


The tables have two columns: one for distances in units of 100, 200, 300 or 500 m (chosen by the participant), the other column contains the time over distance at average speed.


Ideally, this method tells us how much time it should take to cover that distance. First of all a good odometer and chronometer are needed. The odometer and chronometer must be calibrated using the organizer’s same instruments. On starting a time-measured section, the odometer will indicate the distance being traveled and the co-driver will show time after departure and keep the driver informed of any variances from real-time as indicated in the table. The driver will then increase or reduce the vehicle’s speed to achieve those numbers. When both speed and distance match the co-driver will call out “on average”. Penalty points are given based on variations from this figure when the car passes a hidden checkpoint.


2-. A pyramid is an instrument that shows the theoretical or ideal distance we must travel at the average speed entered. This allows a co-driver to avoid dealing with the chronometer and reading tables, comparing instead the car’s odometer with the theoretical or ideal distance indicated by the pyramid. In such cases the unit of adjustment is not time but distance in meters. That is to say the co-driver continually calls out the metric variation in distances and calls out “on average” when they match.


With that explanation, let’s look at what is needed:


1-. OFFICIAL RALLY TIME. The official rally time will be displayed by organizers at the beginning of the race and onboard clocks must be synchronized. It often coincides with RNE. All starts and checkpoints are based on this official time and use it as a reference to determine penalty points for any variances from assigned times when passing a visible or hidden checkpoint.


2-. CALIBRATING DISTANCE. The vehicle odometer must be synchronized with the official one just like the onboard clock so that both readings always match for equal distances. Organizers will indicate to competitors a premeasured straight road segment to use for calibrating their odometers with figures noted both there and back. An official vehicle will travel that segment of road at a constant speed using the right lane and when possible in parallel along the shoulder, that is to say without leaving traces. The competitor’s odometer must match the official vehicle’s on both runs. In case of any discrepancy a competitor must calibrate their odometer using instructions provided by its manufacturer. As many runs as necessary can be performed to calibrate (as close as possible).


3-. COURSE CARD. The course card will be provided by organizers. It will show self-start points for each time and speed section as well as checkpoints where time is recorded. The course card will show departure time at the beginning of the race and indicate each participant’s starting time, either by minute or every 30 seconds. Teams will calculate their own starting time and checkpoint schedule for each time and speed segment in accordance with their competitor number.


4-. ROAD LOG. This logbook will be provided by the organizer and it will serve as a road guide throughout the contest, showing what direction to take, start and finish of speed and time sections and their average speed. Using symbols, notes and total or partial distances the logbook will provide instructions on how to follow the correct route. It will also include a legend to explain what the symbols mean. Competitors can greatly increase their chances of finding their way through difficult segments without getting lost by following the instructions provided in the road logbook. Staying on track can become more important than maintaining average speed.



A-. ACCESSORIES AND VEHICLE: valid license plates and vehicle registration, insurance; Measuring Devices: onboard chronometer or odometer (we recommend not using the stock device); or Terra Trip or Retro Trip (they are more precise), the sensor should be installed on a non-driving wheel. Half Table Control, or Pyramid may also be used. The organizer will provide an identification number that must be installed on either side of the car. Agreements are in place between the organizers and sponsors to have their advertising visible throughout the event.


B-. DRIVER: A is like a captain, his most important task is following the co-driver’s directions. Driving must be done in accordance with traffic laws, in a single lane, without taking shortcuts since this will become apparent when figures are compared. Drivers must attempt to follow a line parallel to the middle or edge of the road, without slewing or sliding the car. Special care must be taken not to spin the wheel on which the odometer sensor is installed. The driver is captain of the vehicle and takes the credit for high rankings. Although a driver is responsible for the car, it is the co-driver who checks fluid levels and performs maintenance.


C-. CO-DRIVER: The co-driver is the team’s navigator and its essential member.

A co-driver has THREE important tasks:

a). Navigate using the Road log.

b). Calculate self-departure times and arrival at checkpoints.

c). Make sure a steady speed is maintained by constantly informing the driver. Check the vehicle fluid levels and perform maintenance; look after the driver and provide whatever is needed (except alcoholic beverages). The co-driver will be blamed for achieving a low ranking either due to navigation errors or average speed penalty points, or any other reason for that matter.
