The other possible documents



To be read by all 



Participation in the TREG® , an event in an unusual and extreme environment, requires, in addition to appropriate training, good health at the time of your participation.





A medical certificate less than one year old is required for all runners as well as an ECG (Electrocardiogram) or an effort test according to the following rules:




The medical certificate and the ECG (Electrocardiogram) must be sent to Isabelle PAUCOT, no later than 31 December 2023, by email to i.paucot at


In addition, the hikers will have to bring in their luggage the originals, or a COMPLETE copy of the documents: ECG - stress test - to present at the individual medical briefing.


It is important that you start the TREG® events in perfect physical condition, as a latent illness can worsen dramatically in the extreme conditions of the event and make rescue even more difficult.




Some other formalities will be necessary to participate in the TREG® adventure




You will need a tourist visa to travel to Chad.
Your passport must be valid for at least 6 months after your return date and have at least 2 completely blank pages. It will cost you 70€.

As we are close to the Chadian embassy, we can arrange for your visa to be issued.




One vaccine is essential, that of Yellow Fever.

Another one is highly recommended, it is the DTP (Diphtheria - Tetanus - Poliomyelitis).

A preventive treatment against malaria is also recommended (see your doctor to prescribe Doxycycline which is much better tolerated by runners than Malarone).


Other formalities concerning the COVID 19 will have to be carried out according to the conditions in force at the time of the trip. Registrants are responsible for these formalities for the departure to Chad. We will organise any formalities in Chad for the return journey.
