Ekiden de Tourraine is a team relay race held in the center of Tours, France, typically in late March. Rather than a single runner completing a full marathon, team members collectively cover 42.195 km on the urban roads of the capital of Indre-et-Loire.
The event format is a single 42.195 km loop, with the day focused on relay dynamics instead of a solo marathon. It accommodates mixed teams and runners of varying abilities, and the finish is a shared experience for teammates in a city offering convenient post-race locations like Saint-Gatien Cathedral and the Loire River.
