ITRA is offering a service of certification of the route and evaluation of the difficulty of trail races.
This service is available as of April 17th 2014.
This service will certify the distance, the elevation gains and losses of a trail race and supply an evaluation of the race's difficulty by assessing it on a range from 0 to 4 points. ITRA will issue a certificate which will allow the organiser to prove the exact distance of their route and/or the number of ITRA points his race has been awarded.
Only trail races (1) may be certified and evaluated.
Certifying a course
The certification of the measurement of a course (distance, ascent/descent) requires that the organiser supplies the GPS tracks (.gpx file) of their course and indicates the GPS tool used.
If the GPS track is of good quality ITRA will be able to measure the distance and certify the elevations. For any further information concerning the use of GPS units click here.
For further knowledge about how ITRA will certify your route: click here.
If the track is not reliable or wasn’t realised with a GPS (track drawn on mapping software or Google Earth for example) ITRA cannot certify the distance and the ascent/descent of the race. Evaluating the difficulty of the race can be realised but on the basis of effort points (see below) calculated with a reliability coefficient of 90% for the imprecision in the measurement of the course.
If the organiser is not able to supply the tracks of their race in the form of a .gpx file, it will not be possible to certify the route nor calculate the difficulty of the race.
Evaluation method for the difficulty of the race
For races in a single stage,the evaluation is the sum of the distance expressed in kilometers and a hundredth of the ascent/descent expressed in meters. For example, the number of effort points of a race of 65 km and 3500 m ascent is: 65 + 3500/100 = 100.
Three other criteria are taken in to account when calculating the number of effort points for a race.
- Reliability coefficient for the measurement of the course: this coefficient is 100% if the course is certified; it is 90% if the track supplied was not of sufficiently reliable or was not made with a GPS; it is therefore 0% if no track is supplied.
- Semi-autonomy: if the number of refreshment posts is such that a race is not run in semi-autonomy, the number of effort points will be reduced according to the following rule.
- Races in laps/loops: for races where the course consists of several identical laps, the number of effort points will be reduced according to the following rule.
According to the number of effort points retained, a race will be attributed:
- 1 ITRA point for the number of effort points between 25 and 39,
- 2 ITRA points for the number of effort points between 40 and 64,
- 3 ITRA points for the number of effort points between 65 and 89,
- 4 ITRA points for the number of effort points between 90 and 139,
- 5 ITRA points for the number of effort points between 140 and 189,
- 6 ITRA points thereafter.
Races in stages
Races run in stages are analysed separately, with as additional criteria the number of stages, the distance and the positive ascent of the longest stage.
Whatever the situation, the number of points allocated to a race is solely the decision of the ITRA’s selection committee.
In the event of the use of an alternative course, the premature stop of a race or of its cancellation, or in the case of known overvaluation of the distance or the positive ascent of the race, the points attributed by the ITRA are recalculated in relation to the actual characteristics, and this could be after the race has taken place.
We would be grateful if you could warn us (firstname.lastname@example.org) if you changed your course on race day. This will allow us to update the relevant edition of your race. So as to allow us to have an idea of the changes, a GPS track of the changes would be welcome; it can either be done by travelling the modifier course or on a mapping software.
