Défi des escaliers SP is a road race in Trois-Rivières, Quebec, focused on stairs, held in late September near the St-Sacrement church. Participants can choose 1 km, 5 km, 12 km, and 17 km routes, suitable for children, walkers, joggers, fast runners, and those seeking a challenging climb. The shortest route includes 2 staircases and 94 steps, while the longest features 17 staircases totaling 954 steps.
The course guides participants through a less-traveled area of Trois-Rivières, emphasizing the stairs as the primary challenge. The 5 km race is divided into waves for fast runners, joggers, and walkers to prevent congestion. The event supports individuals affected by multiple sclerosis. It begins with a ribbon-cutting ceremony involving dignitaries and a spokesperson, and concludes with medal presentations. Progrès 100 limites, a kinesiology services provider, co-organizes the event. Pilaterra offers Pilates sessions for those preferring a lower-impact activity.
