Immerse yourself in the wild and dramatic landscapes of the Côte d’Opale with the Trail des 3 Forts, an experience that goes beyond mere competition to celebrate the beauty and spirit of this coastal region. Organized by enthusiasts for like-minded runners, T3F offers a journey through diverse terrains from Le Portel’s sandy shores to the towering cliffs at Équihen-Plage, passing through Alprech's winding coastal paths along the way. Each kilometer reveals new vistas: dunes stretching endlessly underfoot, rugged cliff edges offering breathtaking views of the sea, and dense forests that challenge even the most seasoned trail runners. The course is a playground for adventure seekers who revel in technical trails and panoramic seascapes. The highlight of the race culminates at the iconic Chaudron Hall, where finishers are celebrated with an unforgettable atmosphere. In 2026, the event expands its offerings to include a twilight run called La Nocturne, which immerses participants in the unique ambiance and stunning views as daylight fades into night. Competitors can choose from various distances: ADN T3F trails of 42 km, 30 km, 22 km, 15 km, and 10 km runs or walks. For those seeking an ultimate challenge, combining La Nocturne with the full marathon is a feat for only the most determined runners. In addition to the race itself, participants receive a range of perks including official merchandise, on-site entertainment, hydration stations, podium awards, pasta dinner (on Saturday), refreshments, and a festive evening celebration. All finishers of the 42 km distance or those who complete the Challenge earn a commemorative medal. For spectators, local restaurants offer dining options without prior booking; simply pay at the venue for meals enjoyed in this vibrant coastal setting. Join Trail des 3 Forts to embrace the spirit and beauty of Côte d’Opale’s trails.
