Ultra Trail Forillon begins in Gaspé, Quebec, at the province's far eastern edge, concluding within Forillon National Park along the shores of Gaspé Bay. This trail-running event takes place over a September weekend on the Côte-de-Gaspé, in collaboration with Parks Canada, offering distances ranging from 1 km up to the 160 km ultra.
The courses primarily follow single-track trails situated between the sea and the mountains. Longer distances are offered at 55 km, 110 km, and 160 km. Participants also have the option to compete over three days as a stage race. The shorter courses, 45 km or less, do not have a time limit, making the event accessible to both novice trail runners and seasoned ultra runners.
