This past weekend, the 2022 Grand Raid de La Réunion — a festival of racing featuring the 100-mile Diagonale des Fous and other shorter-distance events — took place on the island of Réunion, located in the Indian Ocean. Since much of the race takes place on volcanic terrain, the Diagonale des Fous is rightfully known for being one of the toughest 100-mile races on the planet. Photographer and Vert.Run co-founder Kirsten Kortebein (kirsten.kortebein) created these images at the 2022 Grand Raid de La Réunion. Enjoy!
