Trail de Lorette begins and ends at the Chapelle Notre Dame de Lorette, situated 300 metres above Le Quillio in Côtes-d'Armor. This spring trail race takes place in central Brittany, offering recent options of 7 km, 14 km, and 21 km. The shortest course involves an ascent of approximately 180 metres, the 14 km route has about 400 metres of elevation gain, and the 21 km route reaches around 600 metres. Aid stations are provided for each race, catering to local trail runners and those seeking a shorter off-road challenge.
The routes traverse the paths surrounding Le Quillio, featuring streams, natural trails, and a section near the Rocher Merlin landmark. The event is included in the Challenge Bretagne Centre, a series of 13 races in the Loudéac region, and one recent edition reached its 500-runner capacity. Organisers incorporate small community elements: all participants receive a prize, a tombola offers a top prize of 100 euros, and each race includes an unexpected passage through a municipal site. Childcare is available for runners, a candy hunt is planned, and children aged five and up can join kids' activities, which are limited to 30 spots.
