19 Capitales Historico Rally Overview

As I mentioned briefly before, I am working with one of the teams that will be competing in this year’s 19 Capitales Historico rally that will be held in early March in Uruguay.  As part of that work, I have prepared a detailed report outlining how the rally works with respect to the competition aspects and I have provided some suggested techniques, ideas, and also loaned equipment that should provide the team with the opportunity to improve their scores.

The following are some extracts from my report that perhaps some rally competitors will find interesting as this rally competition style, while common in South America, is not common in North America.

The 19 Capitales Historico rally is a time-speed-distance rally that takes place over a five-day period throughout the country of Uruguay.  It is called the 19 Capitales Historico rally as the rally route goes through the capital cities of all 19 provinces of Uruguay and the “Historico” part comes from the limitation that the cars can not be newer than 1981.

The other major limitation in this rally is that the competitors are essentially limited to using the standard odometer that came with the car, but there is no limit on the clocks used or the calculation methodology.  The times to the control points are measured and scored to 1/100 second.  In order to run near the front of the field, the teams need to have an average error from perfect time in the range of 0.10 to 0.20 seconds.

To illustrate some of the issues facing the rally competitors, I have copied some of the pages from the 2014 Day One Route Book.  On these copies I have added some notes in red font to help explain the meaning of the instructions in the Route Book.

As would be expected the route book is written in Spanish, but as the instructions are illustrated with “tulip” diagrams, the route instructions are not too difficult to follow.

The route instructions provide the target average speeds, a total distance traveled, and a target time.  The rally is generally made up of a series of “transit zones” and time control zones.  While the general location of the time controls is provided, the exact location of the time control is not provided.

The key times provided in the Route Book are based on a rally time which has at its origin each competitor’s out time.  This rally time is used throughout the day.

In the transit sections, the competitors are given the approximate distance to an instruction (to a truncated 1/10 kilometer) and the target rally time (to a truncated minute) to that route instruction.  These two pieces of information keep the rally competitors and the overall rally moving at the proper speed.  This is illustrated in the following page from the Route Book, along with some notes in red font that I have added.

Book Sample 2.1

Setting The Rally Time And Timing In A Transit Zone

The competitors follow the route in a transit zone and the transit zone will end at the beginning of a Control Leg.  The competitors are provided with the target rally time that they are to start the Control leg.  The competitors are also told to reset their trip odometer to 0.0 at the beginning of the Control Leg.  An example of this is shown in the following page from the Route Book.

Book Sample 5.1

Roue Instructions And Timing During A Control Leg

The rally competitors are provided with a speed and times to pass specific locations.  Usually near the end of the Control Leg, there will be a specific Control Zone location where the general location of the timing line will be placed.  In the page below, note that this Control Zone starts at route distance 11.775 kilometers at rally time 7:27:04.27.

Route And Timing Instructions In a Control Zone

The page from the Route Book shown below shows that the Control Zone ends at the route instruction at approximate distance 30.7.  At that point the competitors are on a transit again to get to the start of the next Control Leg at approximate distance 53.8 at rally time 7:59:00.  This pattern continues throughout the rally.

This brief review presents a general view of the competition aspects of the 19 Capitales Historico.  Remember that the competitor’s time at the timing lines are measured to the 1/100 second, so precision driving and navigation/timing are needed to do well.
