LUT by Night is the after-dark edition of Lyon Urban Trail, held in November on Lyon's heights between the Rhône and the Saône. It is an urban trail race, not a road run, offering four distances: 30 km, 20 km, 10 km, and a 10 km walk. The short race provides a manageable introduction to city trail running for newcomers, while the 30 km course ascends approximately 1,000 metres, reaching Oullins-Pierre-Bénite.
The race begins at Fourvière, the historic hilltop site within Lyon’s UNESCO World Heritage area. The long course includes about 2,000 steps, offering a clearer picture of the challenge than a flat distance alone. The 20 km route is presented as a focused version of the night race, and the 30 km course carries a suggestion of the SaintéLyon race. Thousands of runners participate, primarily from the Rhône-Alpes region, with some attendees from neighboring European countries. The 10 km walk allows individuals to enjoy the lights, hills, and atmosphere without competing.
