Sweden, together with Great Britain and Ireland, had come loose and lay and cheated on each other before the finish line on the F1 track Fuji International Speedway.
Right at the entrance to the motorway, the Irishwoman Katie-George Dunlevy jerked to an unthreatening gold of 2.35.53 in foggy conditions.
Jannering took on the British Sophie Unwin but never got past and had to settle for the bronze seven seconds after the lead.
Thus, Sweden won the seventh medal and fulfilled the total medal goal before the games in Tokyo.
