TVS - Trails de la Vallée du Scorff 2026 - Cléguer
About the Event
Join us for the grand celebration of trail running at the Trails de la Vallée du Scorff, scheduled for October 17-18, 2026. This will mark the 25th edition of one of Brittany's oldest and most cherished trail races. As part of the Ouest Trail Tour Challenge and the Armor Argoat Challenge, this event attracts some of the best runners from across Brittany. Registration opens on July 1 at 8 PM for a weekend filled with challenging terrain and breathtaking scenery in the heart of Breton countryside. Runners can choose from seven different courses catering to various skill levels, including two nocturnal races on Saturday evening. The Noz Trail offers both an 8Km race starting at 7:45 PM and a longer 12Km route departing at 8 PM. On Sunday morning, the event kicks off with the challenging 54Km course featuring over 1600 meters of elevation gain, followed by shorter but equally demanding races like the 27Km (700D+) starting at 9:30 AM and a more accessible 12Km option beginning at 10:15 AM. For those looking to push their limits further, there are two combined challenges: TVS Bihan combining an 8Km Nocturnal race with the next day's 12Km event, and TVS Bras featuring a longer nocturnal run paired with the grueling 54Km course. Children’s races will also be part of this year’s festivities on Saturday. These events offer young runners opportunities to experience trail running in a fun-filled environment amidst their peers. Participants are reminded that proof of physical fitness, such as an Athlé PPS certificate or valid athletics license, is now mandatory for registration due to the challenging nature of these trails. In addition to the races themselves, participants will have access to exclusive merchandise including this year’s limited edition t-shirt available during online sign-up. Don't miss out on being part of a tradition that celebrates trail running in one of France's most beautiful regions. Join us for an unforgettable weekend where runners from all backgrounds come together to celebrate the sport and the beauty of Brittany's natural landscapes.
