2025 World Championships
July 27 – August 3, 2025 (pool swimming) Singapore, Singapore World Aquatics Championships Arena LCM (50m) Meet Central Live Results SwimSwam Preview IndexWith the Singapore World Championships fast approaching and speculation over relays building, what have the finals for each relay looked like over the last decade?
That takes into account eight world-level international summer meets, and we’ll take a look at the men’s 4×200 free here.
As a preview of what is included here, we’ll go through:
Which nations have been in the final each year The nations with the most appearances How the final time for each finals position has changed How the finals time compares to that countries cumulative time heading into the meet How Swimswam’s predictions have fared over the yearsWe’ll also take a look at the continuity of each final – for a recap of how we calculate this take a look at the methodology explained in this previous article.
The Data
The cumulative times are taken from the calendar year best heading into the World Championships or Olympics of the top four individuals for each nation.
The calendar year best here is used for convenience. Far more of the data processing required here was manual than in an ideal situation, and finding season bests would slightly more than double that.
Additionally, there would come the decision on how to define when the season ends. For Asian nations this is often into the early-to-mid autumn, especially in an Asian Games year, compared to pretty much immediately after the summer meet for European and American swimmers. Using the calendar year best is a cleaner delineation, and the times should be more pertinent to the summer relays as well than those at the start of the season.
These may not necessarily be the swimmers that swim in the relay, and the drops may be due not only to internal improvement but a new swimmer or two.
Additionally, the data here is not 100% complete. The World Aquatics results database used is probably the best for blanket global coverage to the depth required each year, but there are gaps. Most major and national meets are captured, but results from medium to small meets are generally not.
For example, Carson Foster’s 4:08.46 400 IM that he swam at the 2021 Southern Sectionals is not in the database, despite it being the fastest 400 IM time in the world that year.
The result of this is that the cumulative data here is not quite perfect – there are likely a few of the cumulative times that would be slightly faster due to a swim that we’ve not managed to find.
However, with the volume of data and the fact that we’re looking to make general rather than specific conclusions, this should not have a material effect on what we see.
The Finalists
This relay has seen three clear powerhouses in Great Britain, Australia and the U.S., with no one else really establishing themselves either behind them or as a threat to the podium. Brazil’s four-final run from 2019 to 2023 was the longest by another nation, although Korea have made three in a row and have added Kim Youngbeom to a strong core.
Germany have perhaps surprisingly been in six of eight finals over the last decade, driven by a star in 2015 & 2016 (Paul Biedermann) and 2023 & 2024 (Lukas Martens), with an egalitarian approach also putting them in the top eight in 2019 & 2021. That is the fourth-most finals of anyone in this period.
