Rally Maya Mexico is in its fifth running. Created by Benjamin de la Pena Mora, it is a major vintage and classic car events in Mexico and internationally. A new phase is starting with support from:
The rally helps to support medical treatment for children suffering from Type I Diabetes, hearing problems, it also supplies wheelchairs and provides easily understandable health information to adults in isolated communities.
The rally is NOT A SPEED EVENT, all participating automobiles have one thing in common: they must be over 40 years old. Cars are classified solely by their age (1915-1931/1932-1949/1915 1964/1965-1975/). The event is called a Regularity Rally whose object is to travel a specific distance at an average speed.
There are several versions of such events, this one involves MAINTAINING A CONSTANT SPEED ON THE OPEN ROAD, also known as a CLASSIC REGULARITY rally. The route contains several stretches where speed and time must be sustained to achieve a set competition average. Clocked stretches are connected by roads on which there is no set rally speed or time limit although they may contain checkpoints.
A CONSTANT AVERAGE signifies that a specific speed must be maintained in time-controlled stretches. This is an important concept to understand since it is the essence of such competitions.
AVERAGE SPEED CHECK BY THE PARTICIPANT: The Regularity stretch begins at a point designated by the Organizer, and is normally run (and as will be the case in this event) by according to a starting hour, minute and second calculated by using information contained in the route log. Event organizers do not check departure times. From that moment on an average speed must be maintained throughout a stretch. Theoretically this is a simple task that can be achieved by applying the following formula: distance/time, in function of which speed is adjusted; but in practice matters become complex and adjustments for maintaining an average speed can be achieved in two ways:
- Using the traditional method involving charts and chronometer.
- Using an instrument called a "pyramid".
- There are many chart and chronometer systems, but the most common involves the advance preparation of a series of charts (provided by the Organizer as an attachment to the rules) with the different averages at which the competition will be run. For example, there will be charts with average speeds of 35, 40 , 45 and 49.9 km/h.
These charts contain two columns: one is for distances in units of 100, 200, 300 or 500 m (as chosen by the participant) and the other indicating time for the average speed indicated.
In this way we know that for any of these distances the average speed and time it should take to cover them, ideally. It also means a good odometer and chronometer are required. The odometer and chronometer should be calibrated and synchronized with the Organizer's instruments. The odometer will indicate distance traveled and the copilot will keep time and maintain the pilot updated in real-time with information from the chart so that he or she can increase or reduce speed. When the distance and time match the copilot will call out "average". When the car passes in front of a hidden checkpoint any discrepancy in the average, whether above or below, will be cause a penalty.
- The "pyramid" is an instrument that shows what the theoretical or ideal distance needs to be traveled at a specified average speed. This saves the copilot from having to stop and start the chronometer while reading charts; all he or she has to do is compare the true odometer reading with the with the theoretical or ideal figure indicated by the "pyramid". In these circumstances the variable unit is the distance in meters, not time. The copilot reads the number of meters above or below the official average and calls out "average" when they match.
- RALLY TIME. The official rally time with which participants must synchronize is shown at the beginning of the event. It matches RNE. This is the time that will used for all departures and checkpoints and the reference used by hidden or open checkpoints to determine penalty points and times.
- DISTANCE CALIBRATION. The odometer must be calibrated just like the chronometer, so that your instrument will indicate the same distances as the official one. The Organization will set up a calibration stretch and indicate its precise length both going and coming. Participants should travel over that stretch at a constant speed in the right lane, and when possible they should stay parallel to the shoulder without cutting traces. The odometer must match readings in both directions with the distance specified by the Organizer. If the figures don't coincide instruments should be calibrated using the correction formula included with each one, and repeated until they match (as closely as possible).
- ROAD CARD. A Road card will be provided by the Organization. It will show the starting points and time checkpoints for each regularity section. These cards show the departure time at the beginning of the event and the frequency of each participant's departure. Participants must calculate their own departing hour for each regularity section, and the time to pass through time a checkpoint, either in minutes or 30-second intervals. Each participant must calculate their own departure time for each regularity section and the checkpoint passing time based on the card and Dorsal.
- ROAD LOG. Supplied by the Organizer as a guide for the entire route showing what intersections must be crossed, the start and finish of each regularity segment and its average speed. The log will display what route to be followed using a series of symbols and texts, as well as total and partial distances. It will include a legend for the symbols. When traveling over difficult segments of the route it is important to precisely follow any instructions provided in the log. There's more to it than just matching speeds.
- TEAM REQUIREMENTS.
A-. MATERIAL AND VEHICLE: Vehicles must have a valid license plate, registration, liability insurance; INSTRUMENTS: Onboard chronometer or separate odometer (it is best not to use not the stock one). You must be able to install your own instruments. We suggest Terra Trip or Retro Trip (more precise), the sensor should be installed on a non-driving wheel; average chart check or Pyramid or Dorsal. The Organizer will provide identifying and advertising decals to be pasted on either side of the car. The Organizer has agreements with advertisers to display their product name throughout the rally.
B-. PILOT: The pilot should obey the copilot at all times and drive within speed limits, in his or her lane and without cutting corners as this will throw off the distance measurements. He or she should always try to follow a parallel course to the center of the road or the shoulder, without going into slides or skids, especially with the wheel that holds the odometer sensor. The pilot is the aristocrat of the rally, he or she gets most of the glory. They must keep watch over engine gauges and help the copilot to perform maintenance or repairs if they have no support team.
- COPILOT-. The copilot is the brains behind the entire effort, and has three main roles:
a). Navigate following instructions in the road log.
b). Control departure times and checkpoint passage schedules.
c). Help the pilot maintain a steady speed with regular readings. Check fluid levels and perform maintenance on the car while providing the pilot with whatever is needed (except alcohol). The copilot alone will be responsible for a bad showing caused by navigation errors, penalties or other reason.
