PERFORMANCE INDEX<br />
The ITRA’s performance index aims to provide an evaluation of the performance level of trail runners. In particular, it compares the international level of trail<br />
runners against athletes who have never participated in such a competition. But this performance index must not be considered as an international ranking<br />
for trail runners. However, the ITRA is actually studying the possibility of setting up a true ranking which would therefore compliment the performance index.<br />
The performance index is regularly updated (more than 4 900 trail races taken in to account at November 1st 2014 !!!). For each runner, the best 5 races are<br />
taken into account. In the situation where there are not a sufficient number of races, a statistical calculation is made from the known results so as to estimate<br />
their performance level.<br />
TO WHAT LEVEL CORRESPONDS THE PERFORMANCE INDEX?<br />
HOW ARE POINTS CALCULATED?<br />
The distance and the height gain stated by the<br />
organisers are added to the coefficient for the<br />
difficulty of the race. Apart from the distance,<br />
height gain and the difficulty coefficient,<br />
performance is transformed into an equivalent<br />
distance on the flat. Each distance on the flat<br />
is associated with a theoretical maximum<br />
performance (TMP). For each race, each runner is<br />
attributed with a number of points, called “côte”,<br />
out of 1000 which is in relation to both their result<br />
and the theoretical maximum performance<br />
(TMP).<br />
The taking in to account, for each race, of the<br />
distance, the height gain and the difficulty<br />
coefficient allows the attribution of the number<br />
of points (côte) for the different races. Only<br />
the time achieved by the runner is taken in to<br />
account. The runner’s finishing position in the<br />
race is ignored.<br />
This performance index is calculated using all the<br />
trail races which publish an official ranking. With<br />
reference of the definition of trail as defined by<br />
the ITRA, this index takes in to account all those<br />
races in open country which have a minimum<br />
distance on asphalt and which take place in total<br />
or semi self-sufficiency.<br />
The 5 best results from the all the race categories<br />
are taken in to account. In the case where a<br />
runner does not have a sufficient number of<br />
races, a tapered statistical calculation allows<br />
extrapolation of theoretical results of the missing<br />
races, and hence the calculation of the runner’s<br />
performance index. One single race can therefore<br />
be sufficient for a runner to appear in the<br />
performance index.<br />
This performance index is calculated over the last<br />
36 months. This period is long enough to permit<br />
reliable statistical calculations. Furthermore, in<br />
the case of an injured runner, they still appear<br />
in the performance index due to their previous<br />
performances.<br />
The performance index is based on the average<br />
of the runners’ 5 best results, whatever the<br />
category, over the 2 previous years and the year<br />
in progress.<br />
The general index is calculated on the weighted<br />
average of the 5 best results, a mix of categories,<br />
while the category index is calculated on the best<br />
results of the category. For a versatile runner,<br />
often their best 5 races will be spread across<br />
several different categories, which therefore<br />
gives them a better result in the general index<br />
than they would have for each category.<br />
There is one performance index for men and<br />
one for women (but the 2 are calculated using<br />
he same method and it is therefore possible<br />
to compare the level of performance between<br />
people of the opposite sex).<br />
