TC' Color Run 2027

The TC' Color Run is a city run held in late March in Saint-Nazaire, France, offering both 5 km and 10 km routes. It adheres to the Color Run concept: a non-timed paint run without winners or prizes, where participants are showered with colored powder made from food-grade corn starch along the course. Both Saint-Nazaire courses are single loops, one 5 km and one 10 km. The broader Color Run concept originates from Holi and was developed to bring together regular runners, newcomers, and more experienced athletes in a relaxed event. The Saint-Nazaire race also supports a charitable cause, with proceeds donated to Persévérance, the endowment fund of the Institut de Cancérologie de l’Ouest.
