This challenging yet rewarding event takes runners through diverse terrain, from lush forests to rugged cliffs overlooking the Indian Ocean.
The route begins in Cilaos, known for its verdant valleys and winding paths that wind around waterfalls and dense vegetation. As you climb out of this green oasis, the trail transitions into Mafate’s rocky expanse where the only way to reach certain checkpoints is by foot or mule track. Here, runners will experience a unique sense of isolation amidst stunning volcanic landscapes.
Continuing on, the race enters Salazie, characterized by its steep cliffs and deep valleys carved out over millennia by erosion from cascading waterfalls. This section offers panoramic views that reward those who push through challenging ascents and descents.
