Ekiden Millau is a six-runner road relay marathon held in Millau, Aveyron. A team divides the marathon distance into six legs: 5 km, 10 km, 5 km, 10 km, 5 km, and 7.195 km. Millau Sports Events organizes the race, focusing on team pacing, handovers, and assigning runners to suitable distances.
The course passes under the Millau Viaduct and through the Gorges du Tarn region, making the scenery a significant element of the event while maintaining the core format of a road marathon relay. Over 800 runners are anticipated, with participation open from the Cadet U18 category and up, requiring a minimum age of 16. ATS Sport manages the timing and official results.
