The Lyon Urban Trail by Night is an urban trail event held in Lyon, France, typically in November. Participants can select from a 30 km course with approximately 800 m of elevation gain, a 20 km course with about 550 m, or a 10 km course with around 350 m. Additionally, a 10 km hike is offered for those seeking a city exploration on foot without a competitive race.
The night event is an extension of the Lyon Urban Trail, established by Extra Sports as France's first urban trail. The primary Lyon course begins and concludes at Saint-Jean Cathedral, crosses the Saône River multiple times, ascends through parks and historic fort areas, and incorporates the Tunnel de la Rue Terme on the climb. This event attracts both amateur and professional participants, with numbers growing from 1,500 runners at its inception to over 9,000 in its most popular edition.
