Leon Marchand closes his European Championships in Saint-Denis on Sunday 16 August with two finals inside an hour. The 400 metres freestyle is at 19:21 and the men's 4x100 metres medley relay at 20:11, nine minutes after the women's equivalent, both live on France 2. He already has gold in the 200 metres butterfly and silver in the 4x200 metres freestyle relay from this meet.
The 400 freestyle is the interesting one precisely because it is not his race. The swimmer from Toulouse is a medley specialist, and he reached the final by finishing second in his heat in 3:45.85, the fourth fastest time overall. That is comfortably inside the eight but it is not a position of control, and the field includes people who do nothing else. The Hungarian Oliver Papai, the Belgian Lucas Henveaux and the Germans Oliver Klemet and Lukas Martens are all in it, and Martens holds the world record.
A medley swimmer entering a flat 400 freestyle is attempting something specific. The distance suits him because the medley demands the aerobic base, and the stroke does not, because pure freestylers spend their careers refining a single stroke over exactly this distance while he divides his training four ways. Fourth on the clock from a morning heat is a genuinely good position for someone giving away that specialisation, and it is also the gap he has to close in one swim.
Then there is the schedule. Fifty minutes between the end of a 400 freestyle final and the start of a relay leg is not much recovery for an event that empties an athlete, and the relay is where the French team has a real chance of a continental title. Marchand swims it with Maxime Grousset, Yohann Ndoye Brouard and Carl Aitkaci. A medley relay rewards having one exceptional leg among four solid ones, and France arrives with that shape.
The choice this creates is the sort of thing that decides medal counts. Emptying the tank in a race he is not favoured to win costs something in the one where the team is competitive. Holding back in the individual to protect the relay is the disciplined call and a hard one to make in a home pool with a full house. Nothing in the evening's arithmetic makes both outcomes comfortably available.
One footnote from the morning worth recording. Sauveur Cristofini missed the same final by six tenths of a second. Over 400 metres that is nothing at all, and it is the difference between swimming on Sunday evening and watching it.
