Race Info
Marathon Duchesnay-Quebec is a point-to-point marathon that starts at the Station Touristique Duchesnay in Sainte-Catherine-de-la-Jacques-Cartier and finishes at Canadian Forces Base Valcartier, about 30 kilometers northwest of downtown Quebec City. The route follows the Veloroute Jacques-Cartier/Portneuf multi-use trail, mostly on packed stone dust through forest, and is certified by World Athletics. The race debuted in 2024 as a half-marathon-only event, the Demi-Marathon Duchesnay-Quebec, and added the full 42.2K marathon distance in 2025. It is a separate event from the Quebec City Marathon, which runs about three weeks earlier through Old Quebec, Montcalm, and Limoilou.
