If you floated on your back and didn't swim at all, how far would that river take you in one day?

  Would probably suffer hypothermia in that case.

    I'm not French and never swam in the Seine myself, but according to https://ijc.org/sites/default/files/migrate_default_content_files/Seine_River_Temperature_Project_A_FiveYear_Summary_of_Work_Conducted_from_2011_to_2015.pdf https://ijc.org/sites/default/files/migrate_default_content_... it seems the temperatures of the river after June should be at least 16 degress, so you shouldn't get hypothermia in that case.

      Nearly anyone can get hypothermia in 16deg water. Especially if you're in the water for hours and are fatigued.

      Having swam (sometimes not voluntarily) in water temperature from 6deg C upwards, No, 16 deg is hypothermia territory. 20deg C is where you started to be able to swim for extended amount of time (i.e. 1 hr). But the water still feels very cold if it's not a sunny day. Wearing swim shirt is usually recommended. 27-28deg C is the temperature of majority of the pools. 30 deg C is about the temperature of water where you can not move and still feel warm.

  4 km/h on average, less in Paris, more during floods. If he swims four hours a day, that’s 16 km or 10 miles. That’s comparable to a good swimmer. That’s why this part felt interesting: > if he could maintain an average of 10 miles a day, he would need just over 50 days to complete It’s not very warm, so I’d definitely exercise to keep some heat but I don’t know how much of the feat was drifting.
