Course & Elevation
The Marathon Beneva de Montréal is Montreal's marathon, run on a Sunday in autumn with a half marathon, a 10K, a 5K and a mile on the same race weekend. The marathon starts at 7:45 at Parc Jean-Drapeau on Île Sainte-Hélène and heads for the Gilles-Villeneuve circuit before crossing the Pont de la Concorde to Rue Notre-Dame. From there the route continues towards Parc La Fontaine via Rue Atateken and Rue Berri, runs along Boulevard Saint-Laurent as far as the Rivière des Prairies in both directions, and ends at Parc Maisonneuve via Boulevard Saint-Joseph. The course has about 172 metres of climbing and 140 metres of descent, and the time limit for the marathon is six hours. The marathon field is capped at 6,000 runners and was full about six weeks before the 2026 race. The organisers date the event back to 1979; the 2026 race, held in October, was the 34th edition. The 2027 edition is scheduled for a weekend in September.
