Registration formalities


"La Diagonale des Fous", "Le Trail De Bourbon", "La Mascareignes" and "La course en relais, le Zembrocal trail" will take place from 19 to 22 October.

In view of the 2023 registrations for the 4 races organised by the Association le Grand Raid, here is the information that will allow you to register in full knowledge of the facts.


- La Diagonale des Fous: 3000 places offered, distributed as follows:
▪ 1250 places for local resident competitors in the draw.
▪ 1250 places for competitors residing in metropolitan France and Dom-Com (300 by draw and 950 by package sales).
▪ 250 places excluding the draw for foreigners not resident on French territory including Dom-Com.
▪ 250 places reserved for our partners

- Le Trail de Bourbon: 1800 places offered, distributed as follows:
▪ 1150 places for local resident competitors at random.
▪ 450 places for competitors residing on the metropolitan territory and Dom-Com (250 at the draw and 200 through the sale of packages).
▪ 50 places excluding draws for foreigners not resident on French territory including Dom-Com.
▪ 150 places réservées à nos partenaires.

- La Mascareignes: 1800 places offered, divided as follows:
▪ 1150 places for local resident competitors by lottery.
▪ 450 places for competitors residing on the metropolitan territory and Dom-Com (250 by lottery and 200 by the sale of packages).
▪ 50 places for foreigners not resident on French territory including Dom-Com.
▪ 150 places reserved for our partners.

- Zembrocal trail, relay race for 4: 200 teams of 4, i.e. 800 places offered.
As soon as the quota of 200 teams is reached, the registrations for the zembrocal trail relay will be automatically blocked. Once the registration date has passed, no place will be reallocated, even if the teams withdraw: the number of teams remaining will therefore remain as it is once the registration is closed.


Provisions common to all the draws for the competitors whatever their nationality and place of residence

Dates to remember: Pre-registration period from 23 January 2023 at 14:00 to 24 March 2023 at midnight, Reunion time for all.
The draws will take place on 31 March 2023 at 14:00 Reunion time.

These draws will take place under the supervision of a bailiff, it being specified that they will only take place if the number of pre-registration requests exceeds the number of places offered.

All those who, in 2022, were not drawn and did not benefit from the possibility of registering for any race whatsoever, will have a coefficient 2 allowing them to have a better chance of being drawn. This is subject to having pre-registered for the same race as in 2022 and having used the same runner account.

Pre-registration for the draws will require payment in full of the registration fee.
This amount will be refunded to the losers of the draw within one week of the draw.

The pre-registration to the draw is individual on La Diagonale des fous, the Trail de Bourbon and the Mascareignes and concerns only one race. The constitution of a team (of 3 runners minimum) on these three races will only be possible by a team leader (designated by the runners) via his runner’s account directly on the site only after the date of the draw scheduled for March 31st . The latter will make sure that he knows his teammates well so that none of them has already been registered for any race.

As far as the Zembrocal Trail is concerned, the pre-registration for the Zembrocal Trail is for the whole team.
The team leader will pre-register himself and the other 3 members of his team. He or she must therefore make sure that he or she and his or her teammates have a runner’s account ACTIVE and COMPLETE, to know the runner’s account numbers and to make sure that no pre-registration is already registered for another race.

Any pre-registration under the same name for more than one race or for the same race several times will be cancelled! The association will inform the competitors concerned of these anomalies by e-mail.

In addition, a waiting list will be set up by drawing lots on the same day as the main list is drawn. This waiting list will be used to replace, in order of draw, the places that become vacant, it being understood that the same conditions (identity document, points; compulsory standard medical certificate) will be applied.

This list will be updated and published regularly.

Racers who are solicited by waiting list will have a deadline fixed at the time of the solicitation to pay their registration (failing this, the benefit of this possibility will be definitively lost as well as the coefficient 2)

Nominations will be made on the same race from the local or non-resident waiting lists and this until 31 August maximum.


The sale of packages:
It will be entrusted to our partner Bourbon Voyages and will include at least the registration to a race, a round trip air ticket and three nights through a large network of national travel agencies.
Sales open on 09 January at 14:00 (Reunion time)

. No draw for packages.
The choice of package is open to foreigners and nationals not resident in the department.

Foreign competitors will be able to register on the website from 18 January 2023 at 14h00 (Reunion time), without drawing lots.


Piece of identity: It is imperative that you upload a travel document or identity document specifying your nationality to your runner’s account.

It is strongly recommended that you check your email and phone number, preferably mobile, and that you enter the international number allocated to you. Bib numbers will be sent by email.

Points Diagonale des Fous and the Trail de Bourbon:

When pre-registering, you must indicate, in your runner’s area, the race(s) that gave you the points required to run the Trail De Bourbon or the Diagonale des Fous, namely :
Trail De Bourbon: 1 trail giving at least 75 points.
Diagonale des Fous: 2 trails with at least 85 points each.

These points must be acquired between 01 January 2022 and 31 July 2023. As a reminder, the event you are going to justify, gives a certain number of points according to its distance and its positive difference in altitude: 1km of distance is worth 1 point and 100m of positive difference in altitude is worth 1 point. Only races that are exclusively pedestrian, on one stage, with a ranking are taken into consideration and you cannot add up the points of several races to obtain these points. The calculation is based on the distance rounded to the nearest km and the positive difference in altitude rounded to the nearest 100 metres. No points are required for the Mascareignes and the Zembrocal trail. But experience and good training are recommended.
