The Grand Raid of Reunion Island

An iconic race!

Reunion Island, a trail running destination

Reunion Island is heaven on earth for those who enjoy outdoor sports, and there are almost 1,000 kilometres of hiking trails winding all over the island. 42% of the island is listed as World Heritage by Unesco.

You can enjoy all kinds of sports on the ultimate island (MTB, paragliding, diving, deep-sea fishing, canyoning) but one of them is unique, original and sometimes offers a brand-new experience: the Grand Raid of Reunion Island!


The Grand Raid of Reunion Island is considered a legendary “Ultra Trail”, due to the difficulty encountered and the rugged mountain tracks of the island. There are four races in this competition, including the “Diagonale des Fous” (Madmen’s Diagonal) which is part of the Ultra Trail World Tour (UTWT), which groups together the most iconic races in the discipline.

La Diagonale des fous has even been named the most iconic Ultra Trail in the world by the French magazine l’Equipe.

The Grand Raid of Reunion Island: cross the island’s most beautiful landscapes

Reunion Island boasts an exceptional mountainous heritage, contrasted terrain (peaks, high-altitude balconies, natural habitats, plains, rainforests, sheer cliffs, rivers, small islands (îlets) full of history, etc.), and various tourist offers, that ensure this adventure is a huge success every year.


The Grand Raid of Reunion Island departs from the seafront in Saint-Pierre. Runners then pass through the National Park, and cross the three Cirques of Mafate, Salazie and CIlaos. Along the way, they will see the Piton de la Fournaise and the Piton des Neiges and their adventure will come to a close at La Redoute Stadium in Saint Denis.


From Saint-Pierre in the south and Saint-Denis La Redoute in the north, to take on the “Pitons, Cirques and Rampart”, and cross a succession of iconic sites and landscapes, runners need good breathing techniques and tenacity, to face the cool evenings in the highlands and the hot sun throughout the day, where the rugged rocky terrain reveals a primary, wild, unique and spectacular world, with a change of scenery guaranteed.
