The Trail de la Grand'Ville is a trail running event held in mid-April in Bringolo, Côtes-d'Armor, Brittany, France. The races utilize the paths within Grand'Ville park, offering options for both runners and walkers on the same terrain. Participants can choose between a 10 km Discovery Trail, suitable for less experienced runners, and a 20 km Adventure Trail for more seasoned trail runners. Additionally, a 10 km sports walk is available for those who wish to experience the course without competing.
The local association de la Grand'Ville manages the event, dividing the running into two distinct 10 km routes. The TeckTrail is a technically demanding loop with a 1 hour 30 minute time limit and refreshments at the finish. The SoftTrail is a gentler, more accessible loop that includes refreshment points midway and at the finish. The 20 km race can be run solo, combining both loops, or as a duo. In the duo format, one runner completes the TeckTrail before their teammate takes over for the SoftTrail, with both runners needing to cross the finish line together. Walkers follow the SoftTrail course, and a children's race concludes the day within the castle park.
