It is an annual food self-sufficiency race that takes place in April. It was established in 1986 as an independent event and is now the fourth of 10 stages of the Ultra-Trail World Tour, which was established in 2013 and was raced for the first time in 2014.
The route traverses many courses, including dunes, stony plateaus, trails, dry wadis, palm groves, and tiny mountains, over six stages ranging from 20 to 80 kilometers in length, including a 42-kilometer marathon stage and an 80-kilometer non-stop stage.
