*  Solidarity

Solidarity is a value that is practised and shared by the inhabitants at the heart of natural regions, which can become hostile, and consequently they need to help each other to progress better together or simply to survive. In the name of the principle of solidarity, each player in the field of trail-running is asked to prioritise going to the aid of anybody in danger or difficulty wherever they are and in whatever circumstance.

In a more global manner, the participants and players in the trail-running field often show solidarity by making a commitment in favour of environmental, social or societal causes or by helping the underprivileged. Trail-running race organisers implement this principle of responsibility by directly supporting charitable actions and sustainable development; numerous participants “run for a cause” to support the projects of their choice.

Provide a high-quality GPS track

Knowing precisely the difficulty of your trail race allows your future participants to evaluate their ability to take part in it in complete safety. Have your course evaluated by ITRA. The more precise your GPS track is, the more accurately the difficulty level of your trail will be correctly evaluated.

ITRA offers you to evaluate the level of difficulty of your race according to the distance to be covered and the positive and negative gradients present on the course.
The level of difficulty of the course is then translated into km-efforts according to an ITRA points scale. The more precise the GPS trace of your route, the more the number of km-efforts and the associated ITRA points are representative of the real efforts to be made by athletes.

How to make a good GPS trace?

The best way to measure a route is to walk it in its entirety, equipped with a quality GPS unit:
  • Use a particularly recent GPS device with an excellent quality antenna.
  • Prefer a GPS with a barometric altimeter for more accurate altitude measurement. Remember to adjust the altitude before you leave
  • Before you start your reading, delete the old tracks on your GPS
  • Set up your GPS device to record 1 point every 10 meters. Do not set it to take 1 point every X second: If you pause during the tour, the GPS device continues to accumulate many points in the same place, which makes the track heavier and less accurate.
  • At least 90% of your track must include altitude and time stamps.

Validate the trace

During your recording, satellite signals may have been disrupted, especially in some rocky areas. This can result in outliers, several tens or even hundreds of meters away from the real position.
To solve this, load the trace on a mapping software like the one proposed by our partner Trace de trail. You will be able to detect and remove these points easily.

Have the distance and elevation differences assessed by ITRA

Send your trace in .GPX format (procedure to be specified according to process Itra and new site tree structure)
The more accurate your GPX file is, the better ITRA can evaluate your course and calculate its distance and elevation gain in the most accurate way:
calculation of the distance to be covered, considering both the flat distance and the altitude of the points (elevation)
improvement of the precision of the recorded altitude difference: the principle consists in smoothing the altitude curve by calculating a sliding average that does not consider elevation differences between the points as long as they are below a threshold of 3.
Once this evaluation is completed, a number of ITRA points are assigned to your race based on the effort required to complete it.

NB: Aid stations & number of loops also have an impact on the number of ITRA points awarded!
