Each round begins on the Avenue du Parc and it takes only 500 metres before the riders tackle the Côte Camillien-Houde. The climb in Parc du Mont-Royal is 1.8 kilometres long and slopes at 8% and then a steady drop leads onto 1 kilometre on the flat.
The second climb is the Côte de la Polytechnique, 780 metres long and averaging 6%. It contains 200 metres at 11%, which is the steepest section in each round.
The route descends the Chemin de la Rampe before entering the wide Boulevard Edouard-Montpetit. A lefthander and two righthanders lead onto the Avenue Pagnuelo, an uphill of 534 metres at 7.5%. Following 500 metres on the flat the riders fly down the wide Boulevard du Mont Royal to the Avenue du Parc.
The riders continue to go down for 560 metres before U-turn forces them to a virtual standstill. Then they climb the same 560 metres back to the finish line. This section slopes at roughly 4%.
Last year, pre-race favourites Adam Yates, Tadej Pogacar, David Gaudu, Andrea Bagioli and Wout van Aert rode away from the field in the last ascent of the Côte Camillien-Houde. The five opened up a 30 seconds gap before it came down to a five-up sprint on Avenue du Parc. Gaudu opened shortly after the U-turn. Pogacar used him as a launch-pad and kept on pushing. Van Aert lacked the punch to come across and finished in second, while Bagioli came home in third.
