It's 400 IM day for Leon Marchand, as the reigning world champion takes on his best event with a chance to extend his winning streak to five in Rennes.
Leon Marchand already wowed the world with his 200m breast on night 1 of the French Elite Championships and he clocked a 200m free PB during day 2 heats.
Max Litchfield didn't race at the British Swimming Championships but his 4:12.85 400m IM time tonight in Stockholm would have taken the national title there.
