- The races are run in semi-autonomy. Semi-autonomy is defined as the ability to be autonomous between two refreshment points, with regards to one’s own safety, nutrition, and equipment, thus allowing one to be ready to face unexpected problems, for example, adverse weather, physical discomfort, minor injuries, etc.
- In order to limit the production of waste, there are no plastic cups at the refreshment points, it is therefore mandatory that each competitor has a container for drinking.
- The courses are marked with flags, ribbons, and spray chalk marking, except for the IPERTRAIL races where GPS navigation is provided
