On July 2, 2027, the Ultra Tour kicks off at dawn with runners setting out on an epic journey of 170 kilometers through rugged terrain. This grueling route winds its way over six mountain passes and offers breathtaking views of alpine landscapes and pristine lakes. Later in the evening, a more compact but equally challenging event begins: the Trail des Six Cols, covering 90 kilometers with runners tackling each peak under the setting sun. The following day, July 3, sees an array of races catering to various distances and skill levels. Early risers can join the Grande Traversée at 6 a.m., a 105-kilometer trek that showcases diverse landscapes from dense forests to open meadows. Shortly after, the Trail des Crêtes starts at 7 a.m., inviting runners to traverse the ridge line for 65 kilometers through some of the most scenic areas. For those looking for something shorter yet no less thrilling, there's the Trail des Lacs beginning at 8 a.m., winding around serene lakes and verdant valleys over its 48-kilometer stretch. The day concludes with an exhilarating Sky Race du Rif Bel starting at 9 a.m., where participants will race up to the summit of the iconic Rif Bel mountain for just 25 kilometers, offering panoramic views that reward every step. Each event promises a unique blend of natural beauty and physical challenge, making this weekend in July a must-attend for trail runners from around the world.
