The world’s best aquatics athletes compete in the World Aquatics Championships, formerly known as the FINA World Championships, in six aquatic disciplines: swimming, diving, high diving, open water swimming, artistic swimming, and water polo. The Championships started in 1973 in Belgrade, Yugoslavia, but it was in Perth, Australia when the first open water events were added to the schedule.
Over the years, the 5 km race, 10 km race, 25 km race, 5 km 3-person mixed relay, 5 km 4-person mixed relay, and the 4 x 1.5 km mixed relay events have been held.
BLUF (Bottom Line Up Front)
Europe is the epicenter of the world’s fastest open water swimmers, based on the results between 1991 and 2024 at the World Championships.
These results are limited to the World Championships. The historical results of the Olympic 10K Marathon Swim are analyzed here. We thought it was more fair and objective to review the results of the World Championships (where countries send their best swimmers) rather than the World Cup events (where budgetary limitations often reduce the number of participating athletes).

- Europe – 23 Olympic medals
- Americas – 3 Olympic medals

With such a strong long-standing tradition in the sport, we fully expect European countries to continue sending athletes with the following characteristics to the World Championships and Olympic Games:
- A deep passion and joy for competitive open water swimming
- A thorough knowledge of racing strategies
- Years of experience of high-level racing tactics
- Supportive and knowledgeable coaching and support staff
- Training geared at enhancing performances in various bodies of water and in various conditions

World Championship Schedule

- July 16th: men’s 10 km race
- July 17th: rest day
- July 18th: women’s 5 km and men’s 5 km races

3 km Knockout Sprints
The cancellation of the traditional 25 km marathon swim – that started at the 1991 World Championships in Perth, Australia as the sole open water event, created a vacuum in the open water schedule. Originally discussed for many years within FINA and World Aquatics Technical Open Water Swimming Committee members, the new event was first tested at the 2024 World Junior Open Water Swimming Championships in Sardinia, Alghero, Italy to great success and fanfare.
The 3 km Knockout Sprints are a series of 3 races of decreasing distances held over a short time period where the top finishers advance to the semifinal and final rounds. In that World Aquatics test event in Sardinia, Kaito Tsujimori of Japan and Claire Weinstein of the USA finished first in Round 3 to win gold.

Similar to the 5 km and 10 km races, each country may enter a maximum of 2 males and 2 females in the Knockout Sprints.
For Round 1, the entry list will be published in advance of the Team Leaders Meeting. The number of heats to be swum in Round 1 and Round 2 is determined after all the entries have been received and announced at the Team Leaders Meeting. For Round 2, there is a maximum of 2 heats.
In Round 1, each swimmer swim 1.5 km. The swimmers who advance to Round 2 swim 1 km. The swimmers who advance to Round 3 swim 500 meters.
The top 10 finishers from each heat in Round 1 advance to Round 2 – or 2 heats based on the decisions made at the Team Leaders Meeting. If there is 1 heat in Round 2, the top 10 swimmers from Round 2 advance to the Round 3 final. If there are 2 heats in Round 2, the top 10 finishers from each heat will advance to the Round 3 final.
Interestingly and appropriately (in our opinion), if a swimmer receives a 1st infringement during Rounds 1 or Round 2, then this penalty remains in place as the swimmer advances forward in any Rounds. If the swimmer is disqualified or withdraws from Round 2 or Round 3, the position that the swimmer would have finished is awarded to the next competitor and all the lower placing swimmers are advanced one place in the Round 2 semifinal or the Round 3 final.
The podium finishers (gold + silver + bronze medalists) are the top 3 swimmers in Round 3.
