Vietnamese Athletics: The Data Void Hiding the Real Regional Gap

Behind the A stand at My Dinh Stadium, a 400m coach sat down on the concrete and opened a plastic-covered notebook. He wrote each lap in blue ink: the first 200 metres, the second 200, the recovery intervals, even his athlete's breathing rhythm after leaving the track. No device measured anything for him. No software stored a single line. At the end of the session he folded the notebook, pushed it into his back pocket and told me something I have carried for years: "I keep these for myself. Nobody reads them anyway."

The official results sheet for that day carried one line per athlete. A name, a finishing time. For an analyst, that is a single photograph of a two-hour film. Everything that produced the result — how the race was split, the peak speed reached at which metre, the deceleration across the final eighty metres — lived in that notebook and would vanish when its pages ran out.

Numbers tell only half the story; the other half lives in trembling legs on the grass. In Vietnam, we do not even have the first half.

The region moved ahead while we look with the naked eye

Every Olympic cycle lasts four years, and between two Olympics sit four SEA Games. Between two SEA Games sit countless national meets, youth meets and regional meets that almost nobody broadcasts. In Vietnam, athletics is still treated as a gold-mining discipline on the regional stage: at SEA Games 31 on home soil, the Vietnamese delegation topped the medal table with 205 golds; a year later in Phnom Penh the figure was 136. A meaningful share of that came from the track and the field.

At the same time the bigger picture is gloomier. At Paris 2026, Vietnam's delegation numbered 16 athletes and won no medals. Athletics made the trip largely through universality places — a route that measures presence, not performance.

That gap is not new. What is new is how we explain it. Many reports blame insufficient investment, a shortage of talent, or Vietnamese physiology. Those explanations are not wrong, but they are unusable. Answering where the shortfall sits and how large it is requires data. And Vietnamese athletics data, for the most part, does not exist in public form.

Thailand publishes per-lap splits for 400m events at its national championships. The Philippines posts sensor data from training camps on its federation website. Singapore maintains a searchable athlete database. Vietnam has a final results sheet. That is the starting point for everything that follows.

The notebook and the scoreboard

A 400m race is four deliberately different segments. The winner in 47.00 and the third-place finisher in 47.30 can tell two opposite stories: one started conservatively and unleashed at 250 metres, the other flew out and broke at 320. The results sheet swallows that distinction. For a country trying to close a gap, the distinction is the asset.

In May 2026, Nguyen Thi Oanh won two distance golds in events separated by only a few dozen minutes. It was one of the most astonishing physical performances I have witnessed in person. Yet to this day there is no public dataset on her heart rate, lactate levels, per-lap pacing or the recovery window between those two races. We owned a treasure and misplaced the key.

An athletics system that does not record how an athlete runs will never know why it won, and will never know why it lost.

A curve that does not exist on paper

Based on my experience following domestic and regional athletics meets, almost no coach in Vietnam owns a digitised year-by-year personal-best chart for their athletes. Personal records live in memory, passed around over iced tea, and are sometimes misremembered in a flattering direction.

Without that curve, every judgement about an athlete is a single-day snapshot. When Bui Thi Thu Thao took long jump silver at the 2026 Asian Games with 6.55 metres, that was the summit of a multi-year cycle. Understanding how that cycle was built — which year exploded, which year stalled through injury — requires continuous data. We only have the results of that one afternoon.

This feeds directly into risk management. Hamstring strains, Achilles tendinopathy and shin pain from overload all signal their arrival in advance if weekly training load is tracked. Without tracking, injury appears as an accident and enters the report as four words: "unfortunately sustained an injury".

Without a form curve, every judgement about an athlete is a single-day snapshot, and every injury becomes an accident nobody can explain.

Olympic places travel through meets nobody broadcasts

Olympic qualification has two doors. The first is hitting a standard. In the Paris 2026 cycle, the women's 400m standard was 50.95 seconds, the women's long jump 6.86 metres, the women's marathon 2:26:50, and the men's 100m 10.00 seconds. The second door is world ranking points, which requires travelling to numerous small overseas meets to collect them one by one.

Vietnam has walked through the second door successfully in a very narrow event: race walking. Ngan Ngoc Nghia earned a Tokyo 2026 place in the 20km walk. It proves something simple — pick the right event and the right calendar, and have the data to plan, and a country without depth can still buy a ticket.

But choosing that way requires the coaching staff to know exactly where their athlete sits relative to the standard. Without data, every qualification plan is a guess, and guessing usually costs more than rigorous measurement.

A regional map Vietnam cannot see

Southeast Asian athletics has a fairly legible power map. Thailand is strong in sprints and relays. The Philippines has a tradition in hurdles and jumps. Indonesia and Malaysia divide the throws. Vietnam rises in women's middle and long distance, race walking, long jump and some combined events.

Here the analytical question is precise: is Vietnam strong in those events by strategic choice, or because that is where regional rivals are weak? Without event-by-event comparative data we cannot separate the two. And the difference matters enormously: one is expandable capability, the other is a hollow that collapses the moment another country decides to invest.

That map has to be drawn with numbers, not with memories of hearing a national anthem.

The invisible cost of rules and anti-doping

Modern anti-doping is not only a urine test after a race. It rests on the athlete biological passport, a tool that tracks blood and hormone markers over time to detect anomalies. It also rests on whereabouts obligations: three missed out-of-competition tests within twelve months count as a violation.

A small federation, short on medical staff and record-keeping systems, cannot proactively build biological passports for its athletes. The paradox is that this does not make them safer; it makes them more exposed. When an anomalous marker appears, they have no baseline series to show that it is a natural fluctuation of the body.

Shoe regulation follows the same logic. From 30 April 2026, World Athletics capped sole thickness at 40mm for road events. Vietnamese athletes have access to carbon-plated shoes, but few know precisely how many seconds the plate yields them, because no controlled comparison was ever run.

An athletics system with no biological data can neither defend itself against an accusation nor trust itself in the face of a result.

The coach and the system behind him

Back to the coach at My Dinh. He does not lack expertise. He lacks tools, time, and a recording system that would make his work visible.

In many countries, athletics coaches are retrained on a schedule, given accounts on analytical platforms, and assessed on their athletes' data across seasons. In Vietnam, assessment rests largely on medals at one tournament. That approach rewards short-term results and punishes the patience of building foundations.

Overseas training camps are the clearest example. Many trips are organised, but few come with before-and-after data to answer a simple question: how much did this trip help? Without a baseline, there is no conclusion. Without a conclusion, the next trip is decided by feel.

Coaching method never dies; it is merely misunderstood until somebody is brave enough to try it again — and patient enough to write it down.

Risks without names

Every competition plan is a trade-off. Vietnamese athletes are routinely asked to peak at the SEA Games, while Olympic standards fall at a different point in the year. Without recovery data, nobody dares conclude which athlete was pushed to peak too early in a cycle.

Technical risk behaves the same way. A false start in a sprint brings instant punishment, and it tends to strike athletes unaccustomed to stadium pressure. That risk is measurable if you keep statistics on false starts in training and competition. Unmeasured, it becomes luck.

An athlete's risk register is always long: injury, loss of form, a mistimed calendar, the wrong event, psychological damage after a defeat. Without data, that register has no names, no severity levels and no mitigation.

Public narrative when evidence is missing

Every time a young athlete runs fast at a domestic meet, social media attaches a label: prodigy. Almost nobody checks the wind reading on that run. If the tailwind exceeds two metres per second, the mark is not valid under international rules. But the label is already glued on and public belief is already formed.

This is what I call the narrative vacuum. When evidence is absent, the story fills the gap with the cheapest available material: emotion. A young talent lionised too early carries the expectations of an entire sport, and if that athlete fails, the public turns away from what it just built.

Domestic meets play out in half-empty stands. An empty stadium does not lack a contest — it lacks a soul borrowed from the roar. Once the stands are empty, the only thing that can generate pull instead is the number. We do not have the number. The circle closes.

The chain from schoolyard to sponsorship

Behind the track runs a long chain: student recruitment, sports schools, provincial teams, national teams, international meets, media, sponsorship. Every link needs data to make decisions.

A sponsor wants to know what its money produces. It needs viewership, fan recognition of athlete names, and stories backed by verifiable figures. Without a performance database or a properly kept athlete profile, sponsorship proposals become empty promises. And the market moves its money to another sport.

At the youth link the void is more serious still. We do not know how many schoolchildren nationwide run 100m under 11 seconds, how many jump beyond 5.5 metres, or who shows potential in combined events. Without that map, selection happens by tournament batch, by a neighbouring province's recommendation, by coincidence. Coincidence is not a policy.

The medal paradox

There is a counter-intuitive reading of Vietnamese athletics that I believe is more accurate, and it is uncomfortable.

Every SEA Games, we win. That creates a sense that the system works. But SEA Games standards sit a long way below continental and Olympic standards. A regional gold may not be enough to reach an Asian final. When medals become the only yardstick, the system is incentivised to optimise for the easiest thing to measure — placing at a single tournament — and to ignore the hardest thing to measure, which is an individual athlete's genuine progression.

The greatest paradox of Vietnamese athletics is that the more regional medals we win, the weaker the pressure to look at the truth.

I am aware of the argument that the answer is buying more technology, hiring more experts, importing more equipment. I do not believe that is the first step. The first step is far cheaper: publish what already exists. Competition records, year-by-year marks, injury lists, camp schedules, periodic fitness test results. Most of this is already written down somewhere — in a notebook, in a coach's Excel file, in a federation drawer.

Publishing it does not require a large budget. It requires a decision. And once the data is public, it will raise questions that no amount of inspiration can answer.

What remains after the track

At 42, I have learned that every athlete is a poet who never gets published. They write with their bodies, with their breathing, with laps nobody times. My job is not to write their poems for them, but to keep the manuscript.

The plastic notebook at My Dinh may already have been thrown out during a clear-out. But if every coach in the country had somewhere to record those numbers, and every federation had somewhere to keep them, then in ten years we would no longer be arguing about ambition. We would be arguing about method, about volume, about peaking windows. It sounds drier, but that is the argument serious athletics nations have.

Who will be the one to open the notebook first?
