The Empty Wind Column: Vietnamese Women's Athletics and Its Data Deficit

The Empty Wind Column: Vietnamese Women's Athletics and Its Data Deficit

Thong Nhat Stadium, an October afternoon in 2026, the national athletics championships. After the third round of the women's long jump, organisers handed the press tribune a hastily printed result sheet. The wind-speed column was blank, from the first row to the last. For the women's 5,000m, there was no box at all for average pace per kilometre. The athletes had run twelve and a half laps of the track, and the page preserved exactly one line: bib number, name, finishing time.

I still keep that sheet in my bag, as evidence of a gap Vietnamese women's athletics has carried for more than two decades, through a great many gold medals.

In the long jump and triple jump, wind speed determines whether a mark can be ratified as a record. The ceiling is 2.0 metres per second. Above that threshold, the jump still counts as a personal best, but it will never become a record. The same rule governs the 100m and 200m. Without a wind reading, a result becomes nothing more than a story told out loud. It cannot defend anyone, cannot lift an athlete up an international ranking system, and cannot serve as grounds for a training camp abroad.

I came into athletics in 2026, when I joined Runner's World and later spent years in the editor's chair. That is where I learned a principle that has followed me for forty-seven years: a performance only exists if it is recorded properly. No wind, no splits, no track surface, no altitude above sea level, and the mark evaporates from history within three weeks.

Vietnamese women's athletics has performances. Nobody can dispute that. Since the early 2000s, women's teams have consistently contributed the largest share of Vietnam's gold medals at the SEA Games. Nguyen Thi Huyen once dominated the region's 400m and 400m hurdles. Bui Thi Thu Thao won long jump gold at the 2026 Asian Games in Jakarta. Nguyen Thi Oanh became a fixture in the middle and long distances. Le Tu Chinh, then Tran Thi Nhi Yen, carried the sprints forward.

And yet their data record is alarmingly thin.

At the 2026 SEA Games in Hanoi, Nguyen Thi Oanh completed a distance treble: 1,500m, 5,000m and 3,000m steeplechase. A year later, at the 2026 SEA Games in Phnom Penh, she did something close to impossible, winning both the 3,000m steeplechase and the 1,500m in the same session. The recovery interval between her two starts was reported at the time as a shocking detail. But I could not find a single official document recording how many minutes that interval lasted. Nor could I find her 400m splits in the winning race.

That is the part worth talking about. The interval between two events, the distribution of effort over the third 400m, the breathing rhythm on the final lap, the carbohydrate load between races, the length of the re-warm-up: those are the technical story. The medal is merely the last link in a chain of decisions. When the chain goes unrecorded, an entire generation of coaches and young athletes has nothing to learn from.

Without split data, a 1,500m runner is left with two options: run on feel, or copy a foreign training plan that was never designed for a Vietnamese body. Both roads cost time, and time is the most expensive thing in elite sport.

In the women's 400m hurdles, the detail is even more exacting. An athlete must choose her stride pattern between hurdles: thirteen steps or fourteen, a decision that shifts with her lead leg, her height and the fatigue in the final 200m. Nguyen Thi Huyen once reached continental standard in this event. But if someone asked her whether she ran thirteen or fourteen steps in a SEA Games final, the answer would live only in her memory and her coach's. There is no record to cross-check, and no record to pass on.

In the long jump, the situation is similar. Bui Thi Thu Thao won the 2026 Asian title with a 6.55m jump. What was the wind speed? Nobody published it. Technically, the distance is acknowledged, but it cannot serve as a long-term benchmark because the accompanying condition is missing. A 6.55m jump in a 1.5 m/s tailwind and a 6.55m jump into a 0.8 m/s headwind are completely different performances in coaching terms. In the file, they look identical.

I once told a young coach in Hanoi that she should log every single training session herself. She laughed, and said that if some events at the national championships still do not have a wind gauge, then what is the point of the effort. I had no answer.

In neighbouring countries, the picture is different. Japanese athletics meetings publish detailed result files within hours of an event closing, complete with wind readings and lap splits. Thailand and the Philippines have also standardised the use of electronic wind gauges across most jump and sprint events in their national systems. Vietnam has equipment at some major meets, but the results usually surface as a short news item, not as searchable data.

This deficit reaches beyond technical matters. It flows straight into athletes' pockets.

In 2026, while working as a commentator for a television channel during the Tokyo Olympics, I stayed behind to watch the women's football final between Canada and Sweden. Afterwards, Christine Sinclair cried. She said the Canadian women's team received only one-eighth of the men's funding. I stayed in Tokyo two extra days, interviewed her through a window because of distancing rules, and worked with a Canadian female reporter to cross-check the figures. The investigation that followed forced the Canadian Soccer Association to raise the women's team budget by twenty-five percent.

What gave that article its weight was not the tears. It was the spreadsheet. A spreadsheet can be placed on a boardroom table. Tears cannot.

Vietnamese women's athletics sits in the opposite position. The tears are there; the spreadsheet is not.

The state bonus for a SEA Games gold medal is forty-five million dong, plus additional sums from sponsors and local authorities. That money is transparent and deserves recognition. But it is only the visible part. Below the surface lie personal endorsement deals, overseas training slots, nutrition programmes and long-term medical support. Those do not come from medals. They come from the ability to convince someone signing a contract that this athlete will go further still.

To convince, you need a graph.

A sponsor looks at a female 1,500m runner and asks: how much has her personal best improved over three years? If the answer is a vague estimate, the contract is pushed to next year. If the answer is a table with dates, weather conditions and splits, the contract lands on the table within the week.

The counter-intuitive angle

The familiar explanation for every problem in Vietnamese women's sport is a lack of money. I do not deny it. But the order is wrong. The data deficit comes before the money deficit, and it is precisely what makes asking for money impossible.

People often say data does not win medals. True. But data wins contracts, training camps, personal physicians and recovery specialists. Those are what win medals, only at a Games four years later. Vietnamese women's athletics does not lack talent; it lacks the language to prove what that talent is worth.

There is a less comfortable point. A blank wind column on a result sheet is not a technical accident. It is a silence that suits those who prefer to keep everything loose. When there is no standard, nobody is compared. When there is no graph, nobody is asked why this year's training slot was cut from one athlete and handed to another. When no result file is kept for twenty years, nobody has to explain why an athlete who peaked at twenty-two vanished at twenty-six. Silence in data is not neutral. It is a choice, repeated every season, and repeated exactly when it is easiest for no one to notice.

I once wrote a piece on the pressing game of Japan's women's U20 team and had it rejected by an editor on the grounds that it was off-topic. It was later shared by the head coach of Vietnam's women's national team and reached one million views in three days. That rejected article is now the scar I treasure most. It taught me that what is pushed to the margins today is usually what sits at the centre tomorrow.

What needs doing

The task is not as grand as people imagine. Every national championship, every selection trial, needs only to publish a complete result file within twenty-four hours: wind speed for jumps and sprints, 400m splits for middle and long distances, track surface, temperature, humidity. Public, free, archived for at least twenty years.

Such a file costs less than a short overseas training camp. But it is the only thing capable of turning twelve laps of a track into a shared inheritance, rather than a private memory belonging to one runner and one coach.

I am old now, but every call from them makes me young again. The track taught me this: there are lessons that never get rejected. And the first lesson, for Vietnamese women's athletics, is probably just to pick up the pen and write.
