Vietnam's Swimming After Anh Vien: Searching for a Successor or Building a System?

At SEA Games 31 in Hanoi in 2026, when Nguyen Thi Anh Vien touched the wall in the women's 400m individual medley and the podium lit up under the lights of the My Dinh Aquatic Centre, few spectators noticed a detail buried deep in the technical analysis sheet. Her final 50 metres was still among the fastest of the entire field, but her speed in the breaststroke leg — once her strongest weapon — had dropped noticeably compared to earlier versions of herself. People look at the medal. I look at the time between two touches of the wall, because that is where the real story is written.

For more than a decade, Vietnamese swimming has been tied to a single name. Anh Vien's career is one of the finest sports stories in Southeast Asia: from a girl in Can Tho discovered through a talent programme to an athlete who won dozens of SEA Games golds, the first to put Vietnam into an Olympic final in an individual swimming event. But behind the glow of one individual, the structure of the whole sport remains thin. When the guide leaves the pool, the real questions begin.

Swimming is a sport where depth matters more than peak, because a nation cannot live forever on the memory of a single medal.

To understand why, one must look at how a swimming nation operates. In countries that dominate this sport — the US, Australia, China, Japan — there is no "single star". There is a system: thousands of standard pools, tens of thousands of children training from the age of six, a coaching pyramid of hundreds of certified coaches, and a competition structure spanning every level of schooling. An athlete like Anh Vien was not born from nothing; she was the result of a talent programme that, at the right moment, caught a rare gift and then sent her abroad to training camps to fill the gap left by the domestic system.

That is why personalising Vietnamese swimming's story into one person's journey is both a glory and a warning. An exceptional talent can mask the shortcomings of an entire generation. While she was still competing, no one needed to ask about the next cohort. When she stopped, the gap became clearer than ever: after Anh Vien, Vietnamese swimming has yet to produce an individual close to the threshold of an Olympic gold, or even a world final.

Looking regionally, the picture is clearer still. Singapore once had Joseph Schooling, the 2026 Olympic 100m butterfly champion — but that achievement was also an exception bred by a sports-academy system and organised investment, not by luck. Thailand, Indonesia and Malaysia have all built national swimming centres with development programmes from an early age. Vietnam, meanwhile, still relies on isolated training centres in Hanoi, Ho Chi Minh City and a few provinces with tradition, with a limited number of competition-standard pools.

This leads to a paradox. Vietnam has a population of more than 100 million, nearly double that of many other Southeast Asian countries combined, yet its number of internationally competitive swimmers is fewer than in smaller nations. Population does not automatically create athletes. It creates potential, and potential only becomes results when a system converts it — from schools and clubs to youth meets, then to the national team.

I spent years watching youth competitions in the region, and what caught my attention was not the medal count but the number of athletes aged 12 to 15 entering individual swimming events. That is a better predictor than any medal. A nation with 50 fourteen-year-olds swimming below the national standard will have more chances to produce a star than a nation with only five outstanding ones. The mathematics is simple: the probability of finding talent is proportional to the scale of resources flowing into the development pipeline.

Hunting for "the next Anh Vien" is a trap, because Vietnam does not need one successor — Vietnam needs twenty athletes at 90% of her level.

A swimming nation built on one star will always be fragile against injury, age and forces beyond its control. A swimming nation built on depth can absorb individual losses and still hold its place. Look at Australia — where I live and work — and the lesson is clear. Australia does not produce a single superstar who defines the whole sport; it produces a stream of athletes deep enough that every Olympic cycle has someone on the podium. When one generation retires, the next is already ready. That is the result of a system, not a miracle.

So what does Vietnam need? First, infrastructure. A nation that wants to compete at continental level needs more 50-metre standard pools. Second, a coaching workforce with proper training, paid well enough to stay in the profession long term. Third, a continuous competition structure from school to national level, so young athletes get regular exposure. And finally, a philosophy of sustainable development that does not chase short-term results at SEA Games.

This is where I want to aim my counter-argument at the way we usually talk about elite sport. We love individual stories — and there is nothing wrong with that. But when an individual story becomes the entire story of a sport, we have staked the future on a single variable. Anh Vien deserves every praise. But she should not be the whole legacy of Vietnamese swimming. The real legacy must be what remains after she leaves the pool: a system that can run itself.

The data tornado of this sport — the numbers of time, distance and rhythm — does not exist to glorify individuals. It exists to reveal gaps. And the biggest gap in Vietnamese swimming is not in the lane. It is outside the pool.

Football without spectators once taught me that silence in the stands is not a loss of data — it is a new kind of data. The same is true of Vietnamese swimming after Anh Vien: the absence of a star is not a disaster. It is a signal. The question is not "who will be the next Anh Vien", but "how many lanes will we build before we find the next one".

When the crowd asks "where is the next gold medal", people in my profession must ask "where is the next pool". Because results are only a consequence. The system is the cause. And in a sport measured in hundredths of a second, one can see the difference between a good athlete and a strong sport — but only if one is willing to look beyond the lane.

Sport, after all, is a common language. And in that language, depth always says more than a solitary echo. What Vietnamese swimming needs is not a new hero, but a new generation — and a system patient enough to raise it.
