That 1:55.35 is faster than Wang Shun went at trials last year and then he went 1:54 at Asian Games later in the year. If Marchand wants that gold he's gonna have to swim a best time in the Olympic final after a very heavy program consisting of 2 x 400 IM, 3 x 200 FL, 3 x 200 BR and 2 x 200 IM plus some relays while Wang Shun will probably only have swum 2 x 200 IM plus maybe the 4x200 relay final. It'll be a massive feat if Marchand can pull it off.
