About 2026 100KM d'Espoir
The 100KM d’Espoir is a charity Backyard Ultra at Parc du Domaine Vert in Mirabel on Saturday, August 29, 2026. Organizers describe a roughly 5 km loop that starts every hour for up to 20 hours, with runners continuing only if they finish each loop before the next hourly start. Formats include an individual challenge and team options of two, four, or five, with team rules limiting each hourly loop to one teammate.
The event raises funds for Leucan, supporting children living with cancer and their families, and registration materials state that event profits go to the foundation. The setting is framed as a community gathering in nature, with aid stations and on-site partner activity through day and night. For more Quebec options, browse races in Quebec.
