Trail des Bracelets Bleus is a short charity trail event in Lunéville, starting from Place des Carmes. The main run is a 6 km loop with 125 metres of climbing, open to runners over 12, and it can be done solo or as a team of two or three. The same 6 km loop is also used for the Nordic walk, while families get a shorter 4.5 km walking route. Entry is kept simple and low-cost, with a 5 euro fee per participant.
The race is organised by the City of Lunéville for Comité 54 of the Ligue contre le cancer. Its blue-bracelet theme links it to Mars Bleu, the French national campaign that encourages colorectal cancer screening. Comité 54 members set up an information booth at the event, so the day is not only about running or walking but also about direct health awareness. The format makes room for club runners, casual walkers, teams of friends, families, and people who mainly come to support the cancer charity.
