Vietnamese Swimming After Ánh Viên: The Empty Lane and the Problem of Keeping Athletes

On the afternoon of May 19, 2026, from a corner of the stands at the My Dinh Water Sports Palace, I heard the water break before I looked up at the scoreboard. It was the sound of an arm striking the surface in lane four, where Nguyen Huy Hoang was swimming the men's 1500m freestyle final at the 31st SEA Games. That sound was different from the water in the other lanes. Heavier. Shorter. And so even it was almost strange. I sat in the seventh row, less than thirty metres from the pool. Close enough to see Huy Hoang's shoulders rise above the surface on a rhythm that barely changed across fifteen laps. Close enough to see something else: from the seven-hundred-metre mark, the gap between lane four and the two lanes beside it began to widen in a way a spectator can measure with the naked eye, without a stopwatch. When he touched the wall, the first thing Huy Hoang did was not look at the scoreboard. He turned to the lane beside him, where opponents had just surfaced, shoulders still shaking. I do not know what he was looking for there. I only know that I found what I needed. What I carried home from that afternoon sat outside the medal. It was a question I have carried for four years since: through the 32nd SEA Games in Phnom Penh, through the 19th Asian Games in Hangzhou, through mornings sitting at Phu Tho pool counting how many lanes were still in use. If Huy Hoang stops, who swims lane four for Vietnamese swimming? The question sounds like the story of one person. It is the story of a system, and that system already has a template answer from a decade ago. A DECADE BUILT AROUND A SINGLE LANE In 2026, in Incheon, an eighteen-year-old girl from Can Tho stepped onto the top step of the 400m individual medley podium at the Asian Games. Nguyen Thi Anh Vien became the first Vietnamese swimmer to win an Asian Games gold medal. The entire sporting establishment learned a new word that day: swimming could stand at continental level. The road to Incheon looked like nobody else's road. Anh Vien was identified as a child, sent to Bolles School in Jacksonville, Florida, in the United States, training long-term with coach Dang Anh Tuan under a special arrangement involving the sports administration and the federation. She grew up in internationally standard pools, raced meets where every heat had rivals of her own level, and returned to the SEA Games like a harvester. Twenty-five SEA Games gold medals. That record has been repeated so often it has become a proper noun, and precisely because it has been repeated so often, few noticed that behind it stood a structure with room for exactly one person. In 2026, the SEA Games came home to Hanoi. It was the first edition in a decade without Anh Vien on the blocks. The stands at the My Dinh Water Sports Palace that May were so full that organisers issued tickets in timed slots. Vietnamese people still love swimming. They simply love one particular lane. At that edition, Nguyen Huy Hoang carried most of the expectation. Born in 2026, he already owned a serious collection: silver in the 1500m freestyle and bronze in the 800m freestyle at the 2026 Asian Games in Jakarta, SEA Games gold medals, and two Olympic appearances, at Tokyo 2026 and Paris 2026. Beside him stood a small group: Tran Hung Nguyen, Pham Thanh Bao, Vo Thi My Tien and a few younger faces. But a small group is not a generation. And a generation is not a system. WHAT VIETNAMESE SWIMMING LACKS IS NOT TALENT To judge whether a swimming nation is strong or weak, people usually look at medals. I look at three other things: the average age of the national team, the number of athletes within three per cent of the national record, and the number of long-course meets held in a year. In Vietnam, all three point to the same story. The national team contains a paradox: the best swimmers sit at the two ends of the age range, and the middle is empty. At the lower end are fourteen- to seventeen-year-olds, old enough to swim fast and young enough not to have made any big decisions yet. At the upper end are those who survived past twenty, usually thanks to a special arrangement or a particular set of circumstances. The middle, from eighteen to twenty-three, is a dropout zone. That zone is not a natural phenomenon. It is the product of a very specific chain of decisions. At eighteen, a Vietnamese swimmer faces two doors. The first is the school-leaving exam and university, where training twice a day becomes a choice almost impossible to explain to a family. The second is staying in sport, on a provincial athlete's income, inside a system where university places, payroll positions and post-retirement futures are all unclear. There is nothing mysterious about most of them choosing the first door. What matters is that the second door has never been opened wide enough. Worldwide, swimmers peak between twenty-two and twenty-six. That is the window when the body has passed its growth phase, technique has settled, and the mind is cold enough to swim the last three laps of a final. Vietnam loses exactly that window. We develop twelve- to seventeen-year-olds extremely well, then let athletes walk away just as they begin to be able to repay the investment. One confusion recurs in policy discussions: treating mass swimming and elite swimming as one thing. The two systems have different goals, different budgets and different metrics. Mass swimming saves people from drowning, and that is its greatest mission. Elite swimming produces international competitors, and it needs its own pipeline, fed by its own coaches and its own pools. When the two are merged into one budget line, the system with less media weight crowds out the other. FIFTY-METRE POOLS AND THE PRICE OF A LONG LAP There is a detail rarely mentioned in discussions about Vietnamese swimming: most pools in the big cities are twenty-five metres long. A twenty-five-metre pool serves the grassroots very well, serving children learning to swim, serving water-aerobics classes. It cannot serve the preparation of a 1500m freestyle final. Long swimming in a short pool forces an athlete to rotate twice as often, splits the breathing rhythm, and distorts the sense of speed. Someone can swim beautifully in a twenty-five-metre pool and still lose the rhythm the moment they step into a fifty-metre pool at an international meet. In Hanoi and Ho Chi Minh City, the number of competition-standard long pools can be counted on one hand. They usually sit inside national sports centres, serving the national team and talent classes, under enormous pressure on pool time. A provincial coach who wants his or her athletes to get used to long-course racing must request slots, travel, and accept that every session is as precious as a ration. That is an infrastructure problem, but above all it is an opportunity-cost problem. Every hour in a fifty-metre pool that a young swimmer cannot access is an hour spent training with a false feeling about their own race. This also explains a familiar paradox at domestic meets: the same swimmer can look very fast over short distances and fall away markedly over long ones. That is usually not a fitness problem. It is a training-environment problem. THE COACH, AND HOW FEW COACHES THERE ARE In every sport there is an asset money cannot buy instantly: a coaching corps with elite competitive experience and the ability to transmit it. Vietnamese swimming has a few such names. They tend to be people who have tied their whole careers to one group of athletes, working under conditions where income does not match the volume of knowledge they must hold. They must understand physiology, video analysis, shoulder-injury management, and the psychology of a fifteen-year-old who has just lost a final. The problem is that there are fewer such people than there are lanes in a national final. When a system depends on four or five individuals, it cannot scale. A good coach can only handle a small group, and when they step away, an entire cohort goes with them. Coach education in Vietnam has made progress, with certification courses and international cooperation programmes. But the gap between a certificate and practical capability remains. A coach only truly matures after guiding an athlete through three or four major competition cycles, watching them fail, then watching them come back. Vietnam does not yet have enough people who have walked that whole road. Injury is another part of this story. A swimmer's shoulders carry an enormous training load, and a breaststroker's knee is one of the most vulnerable joints in elite sport. Early detection and proper rehabilitation require a physiotherapy team with genuine expertise, and that team remains thin in Vietnam relative to demand. THE CALENDAR: PEAKING ONCE A YEAR To judge whether a country has a swimming culture, count the long-course meets in a year. Athletes from strong swimming nations race all year. They have national championships, regional meets, open internationals, and overseas training-and-racing trips. Every appearance in a final is a lesson in handling pressure. Thirty times a year produces a very different athlete from three times a year. In Vietnam, the domestic calendar is thin. Athletes tend to concentrate their entire cycle on one or two major meets a year, with the SEA Games as the most important destination. This approach has the advantage of optimising medals in the short term, and the fatal disadvantage of turning an athlete into someone who only knows how to peak once. Young swimmers sent abroad to compete several times a year learn something no training plan can teach: what it feels like to stand behind the blocks knowing in advance that you might lose. That is the foundation of every record. Vietnamese athletics, with similar funding constraints, is ahead of swimming on this point. National athletics championships are held more regularly, city and club competitions are more numerous, and athletes get more chances to compete at home before stepping onto the continental stage. I once stood at Bukit Jalil stadium in 2026, when Nguyen Thi Huyen crossed the line in the 400m hurdles. Huyen crossed the finish line, and I crossed the boundary of my own profession. That was the first time I understood that one medal can be the result of ten years of one person's persistence, but a generation of medals can only be the result of a system that knows how to keep people. SPORTS SCIENCE AND A POOL WITH NO LABORATORY One of the questions I receive most from young readers is: why does Vietnamese swimming not apply sports science more forcefully? The answer is simpler than people assume. Sports science is not a device; it is a process. To measure blood lactate after each swim, you need someone to draw the sample, a machine, someone to read the result, someone to adjust the training plan based on that result, and a coach who believes in it. At many Vietnamese centres, those steps exist but are disconnected. A VO2max test is carried out well, the results are printed, and then they sit in a drawer. The missing feedback loop from data back into the training plan is a bigger bottleneck than missing equipment. In Asia's leading swimming nations, meanwhile, a fifteen-year-old already has a personal physiological profile, defined aerobic and anaerobic thresholds, and a weekly plan built on those thresholds. By the time they turn twenty, they have five years of data about their own body. The difference between the two approaches does not show up in this year's medal. It shows up in whether an athlete, entering a four-year cycle, knows exactly where they stand. Athletics offers a clear counterpoint. Vietnamese 800m and 1500m runners have long been used to pacing their races by lap, by threshold, by heart rate. That split-analysis technique, transferred to the pool, could turn a swimmer who races at one speed into someone who accelerates over the final two hundred metres. Talent identification is part of the science story too. In many provinces, spotting talent still relies mostly on a coach's eye and on results at school sports festivals. That approach has produced great athletes and will produce more. But it cannot measure the qualities that decide long-distance races: lactate tolerance, propulsive efficiency, and muscle structure suited to specific events. MONEY, BROADCAST RIGHTS AND STORYTELLING You cannot discuss swimming without discussing money. Budgets at national training centres are allocated along SEA Games and Asian Games cycles. This creates very clear clusters: the three years before a Games are the development phase, the year of the Games is the harvest. The post-Games period is usually a silent one, when athletes must find their own ways to hold form. Beyond state budgets, the second key resource is sponsorship. Vietnamese sponsors tend to flow towards football, and in recent years towards the senior men's national team. That is understandable, but it creates a structure in which a handful of swimmers can attract attention through personal stories while the rest of the pool cannot. Upstream, another story is unfolding. The sports broadcast-rights bubble has peaked, and streaming platforms are repeating the mistake television made a decade ago: paying too much for a rights package, losing money, then cutting other investments. For non-football sports, that means airtime shrinks as the bubble deflates. A sport that is not broadcast will struggle to produce its next generation. And a next generation that is never seen will not believe the sport has a door. Here, my own profession sits inside that circle. For years, Vietnamese swimming appeared in the press only on medal days. The rest of the time the pool was silent, and that silence quietly taught audiences that the sport exists for a few weeks every two years. THREE BELIEFS TO LEAVE BEHIND Belief one: we need another Anh Vien. This is the most comforting belief and the most wrong. It looks backwards and turns a special case into a replicable model. Anh Vien's career was built on a dedicated mechanism, a dedicated coach, a dedicated overseas training base and dedicated resources. None of that can be reproduced for ten swimmers at once. If Vietnamese swimming waits for a second exceptional individual, it may wait for years, and while waiting it will lose a whole cohort that could have stayed. Belief two: the SEA Games is the yardstick. At regional level, a gold medal is a real achievement. But using it as the yardstick for an entire sport's development means fooling ourselves. SEA Games swimming lacks the depth of the Asian Games. A SEA Games champion in one event can finish eighth or tenth on the continent with the same time. The right metrics for this phase are preliminary heat times at a continental meet, and the number of athletes within three per cent of the national record. Those two indices reveal the system's real strength; regional medals only reveal the result of one week. Belief three: sending children abroad is a system. It is the fastest way to learn, and in some cases the only way. But if each cohort only sends one or two swimmers abroad, we are buying lottery tickets rather than building a road. Vietnamese football has already learned a version of that lesson elsewhere. For years, the inverted winger was treated as the only template, and an entire generation of traditional wide midfielders was erased from youth curricula. The result is that teams have fewer options when a match needs someone to run the touchline and cross. Pressing is not a tactic; it is a love letter to the ball. But love also needs variety, otherwise it becomes a single beloved. Swimming risks the same. If we only develop one athlete archetype — tall, long-armed, specialised in one event — we will have a few standout individuals and a fragile sport. The empty stands of 2026 taught me that sport is never silent; it only changes its voice. The pool is the same: it does not disappear when nobody is watching. It only waits. WHAT IS WORTH WAITING FOR Based on my experience covering meets at SEA Games and Asian Games, one point is rarely made: the quality of a swimming nation usually does not change at a Games. It changes in the three years before it, when nobody is paying attention. What is happening in Vietnam now offers a few signals worth tracking. Long pools are being added in some localities. Coach education programmes involve more foreign experts. Groups of young athletes are being sent to compete abroad more than once a year. These are small changes, but they move in the direction a system needs. What remains is time and patience. A generation of swimmers takes ten years to form, and within those ten years there will be SEA Games editions where Vietnam wins fewer medals than fans expect. How we respond to those editions will decide whether the system has enough runway to keep going. There are races not measured by the clock, but by the silence between two breaths. Vietnamese swimming's race over the next decade is one of them. It will not be counted in medals in Phnom Penh or Chonburi, but in the number of twenty-two-year-olds still in the pool when the season ends, when nobody is left in the stands, when there is only the sound of water and one person wondering whether to continue. In silence, an athlete's heart beats louder than any cheering. Our job is to give that beat somewhere to echo for longer than a few years.
