Experience the enchanting landscapes of TBR TRAIL BREIZH REDER, where runners will be captivated by the beauty and diversity of trails that wind through the valleys of Trédias and Mégrit. The 2026 edition promises to be even more spectacular with new routes opening up for your enjoyment. Four courses cater to various skill levels: - A 3.3km route, perfect for adult novices running alongside minime runners (though only minors will compete in this category). - A 7km course suitable for everyone from cadets and above. - The 12km "Picotous" trail with a challenging 350 meters of ascent, also open to cadet-level athletes. This route has been revisited and improved upon, offering an already beautiful path that shares sections with the more advanced 18km course. - An exceptional 18km challenge through mountain trails, featuring over 600 meters of ascent from a cadet level starting point onwards. This is not just one of the most scenic routes in the Dinan-lamballe region; it's also an unforgettable trail experience. For those seeking something less intense but still rewarding: - Randonnées (7km and 12km) start between 13:00 and 15:00. - Baby Athlé events for children aged baby to minime, starting at 15:00. - Ecole Athlé courses from 15:15 with distances of approximately 300 meters (from 2020 to 2021 and 2022). - Poussins races around 1450 meters in length, beginning at 15:30. - Benjamins running a slightly longer distance of about 2.8km starting at 16:05. The 7km trail is open to all athletes from cadet level and above with approximately 85% of the course on trails. The 12km route, which covers around 95% of its length off-road, starts at 17:30 for participants who are ready for a more demanding challenge. The 18km trail offers an even greater adventure with about 90% covered by trails and begins the race a bit later at 17:50. This course is not just challenging but also scenic, making it one of the most beautiful in the region. Participants can expect live tracking via ChronoWest with intermediate points on all courses, as well as live streaming on Facebook BREIZH REDER. The event will be animated by Fréhel Sono, adding to the festive atmosphere. Restoration and refreshments are available throughout the course of the races, ensuring that runners stay fueled for their journey. Dossards can be collected from 14:00 onwards at Trédias Town Hall or the Festival Hall, with a celebratory ambiance awaiting everyone after the finish line. Don't miss out on this unique opportunity to explore some of Brittany's most picturesque trails and compete in races that cater to every runner’s level.
