Ultra 93 is a trail running series held in Noisy-le-Grand, Seine-Saint-Denis, east of Paris. It takes place in late April and features four distances: approximately 11 km, 27 km, 50 km, and 85 km, allowing participants to select anything from a brief trail run to a full ultramarathon.
The main race covers 84.55 km with 1,300 metres of elevation gain, while the shorter races have less climbing. The event emphasizes its local character with the slogan “Seine-Saint-Denis Style,” portraying the 93 as a region of direct terrain and direct people. The description indicates that the longer routes challenge both mental and physical endurance. A previously scheduled edition was canceled, and registration for it was closed.
