The TC Color Run is a charity color run in Saint-Nazaire, held in spring at Parc Paysager and organized by students from the IUT’s Techniques de Commercialisation program. It focuses on short, accessible distances rather than competitive racing: runners can choose a 3 km option in the early afternoon or a 10 km option later in the day, with modest entry fees and all money raised going to Restos du Cœur in Saint-Nazaire.
The race is as much a color party as a run. Participants usually start in white shirts, then get hit with clouds of pink, blue, yellow, and green powder around the course, with organizers waiting at turns to cover them as they pass. The event often fills quickly, and the park setup includes on-site activities, prize draws, cake sales, and a refreshment stand, so even people without a bib can still come for the atmosphere and support the charity.
