The Course des Lumières Toulouse begins at Pont-Saint-Pierre, guiding participants through the city as dusk settles. Runners and walkers carry illuminated items, lighting the way to support the Fondation Toulouse Cancer Santé. The event offers 5 km and 10 km distances: a timed 10 km for competitive runners, a non-timed 10 km named Le 10km des Lumières, a 5 km company race, a non-timed 5 km, and a 5 km walk suitable for families and friends.
The courses conclude at Cours Dillon, where the event village features a DJ, food vendors, and a dedicated business zone for corporate teams. Individuals can participate alone, with colleagues, or as volunteers. This creates a diverse field, blending runners focused on their performance with groups participating for the event's charitable aspect. The timed 10 km is a recent addition, while the established tradition of carrying lights defines this Toulouse event.
