There was no question of who the queen of Copenhagen was in 2017 when Katinka Hosszu ruled supreme at the LEN European Short Course Swimming Championships.
The Hungarian superstar achieved the unthinkable as she retained all six individual titles she had claimed two years prior in Israel.
Focusing on the backstroke and medley events, Hosszu was the standout performer with victories in the 50m, 100m and 200m backstroke, as well as the 100m, 200m and 400m medley.
The most dominant of those performances, and the most dominant result of the entire meet, came in the 200m medley, where Hosszu finished more than three and a half seconds clear of compatriot Evelyn Verraszto in silver.
Of course Hosszu was not the sole standout performer in Denmark. Her six gold medals helped Hungary to second in the overall medal table with their eight golds one fewer than Russia.
The star for Russia was then 17-year-old Kliment Kolesnikov, who won the 100m and 200m backstroke, the 4x50m freestyle relay, and swam the lead-off leg in the 4x50m medley relay in which the Russians broke the world record.
That was one of three relay world records at the Championships, with the Netherlands doing the same in both the women’s and mixed 4x50m free.
The Dutch also won the mixed medley relay with Ranomi Kromowidjojo part of all three, while also taking 100m freestyle and 50m butterfly gold.
In fact the Dutch star almost matched Hosszu’s feats with a silver in the 50m freestyle, just one hundredth behind Sarah Sjostrom.
So when it comes to Glasgow 2019, will anyone be able to top Hosszu’s achievements?
