Vietnamese Swimming Is Missing a Notebook, Not a Lane

Vietnamese Swimming Is Missing a Notebook, Not a Lane

I was standing in the mixed zone of the My Dinh Water Sports Palace, pen in hand, eyes fixed on the door of the timing room. The 200m individual medley final had just ended. I needed exactly one thing: the 50m split sheet for the eight lanes. In Tokyo 2026, that sheet reached my hand less than three minutes after Karsten Warholm hit the wall in 45.94 seconds in the 400m hurdles. In My Dinh, I received a polite answer: final results would be published, splits would not.

I went back to my desk with one line of numbers. Exactly one line.

My job lives in the gap between two presses of the timing pad. Some races are not measured by the clock, but by the silence between two breaths. Most of Vietnamese swimming's silences have never been recorded, and that is a greater loss than any medal slipping from a hand.

Context

Over fifteen years, Vietnamese swimming has produced results worthy of a place in the nation's golden ledger. Nguyen Thi Anh Vien won eight gold medals at the 2026 SEA Games in Singapore and eight at the 2026 SEA Games in Kuala Lumpur, after competing at the London 2026 and Rio 2026 Olympics. Nguyen Huy Hoang took silver in the 800m freestyle in 7:50.41 and bronze in the 1500m freestyle in 15:01.63 at the 2026 Asian Games in Jakarta-Palembang, according to the official results of the organising committee. The next generation includes Tran Hung Nguyen, Pham Thanh Bao and Nguyen Quang Thuan, along with a group of young swimmers pushed into the national team after every major meet.

Those results were recorded. The ways of producing them were not.

At meets run by World Aquatics, every swim comes with a split sheet: each 50m, turn times, reaction times measured in hundredths of a second. That data sits openly on the results page for anyone to check. At domestic meets and most SEA Games editions, what gets published stops at the final time. There is no open database, no split sheet to look up after the meet, no technical record of an individual swimmer across the years.

I once sat down after a regional Games to find the splits of a Vietnamese swimmer I had just written three articles about. I searched the official results page, the press releases, the timing company's data. Nothing. To know where she lost time, I had to ask her own coach, and the answer rested on memory rather than any page of data.

Analysis

An 800m freestyle split sheet holds sixteen lines. Fifteen turns, one touch at the wall. A swimmer who loses an extra 0.2 seconds on each turn loses three seconds overall. Three seconds in the 800m freestyle is the distance between a final and a heat at continental level, the distance between an Olympic berth and another season watching from home.

Without that sheet, every technical argument collapses into impression. Nguyen Huy Hoang is known for finishing fast. I have written that, and I still write it. But to prove it with data, I need to know how much his first 100m and last 100m differ. At the 2026 Asian Games, I could rewatch the entire race on video, hand-timing each lap off the screen. I did that once for a piece on the men's 1500m. I could count stroke rate, but I could not know precisely how many hundredths of a second he lost on each turn, because the camera angle never got close enough to the wall.

With the 200m individual medley, the gap hurts more. This event has four strokes, three transitions and seven turns. The breaststroke-to-freestyle transition is the costliest, because the swimmer must rebuild breathing rhythm and stroke rhythm almost instantly. Nguyen Thi Anh Vien once held an advantage on her turns. With data, we could say exactly how much faster she was than her rivals off the wall, and in which year. Without it, everything is oral history, and oral history dies with the generation that carries it.

Based on my experience covering meets and major Games, most of the technical information Vietnamese media obtains about domestic swimming comes from what coaches say after the race. That source is valuable, but it cannot be reused. A coach of a later generation who wants to know where a swimmer stands against continental standards can find nothing beyond a medal list.

Swimming is one of the rare sports where the performance itself is raw data. Every swim generates hundreds of data points, almost for free. Choosing not to keep them is a decision, not a technical limitation.

The Contrarian Angle

When Vietnamese swimming fails at a major Games, the list of reasons is always read out almost identically: fitness is short, pools are scarce, the talent pool is thin. Those reasons are partly true. They do not explain why the same mistake repeats across three different generations of swimmers.

What is missing is the sport's memory. Every generation of swimmers leaves and takes all knowledge of itself with it. The next generation starts from zero, guessing again at the previous one's weaknesses, fixing again mistakes that were already fixed once. A swimming nation that cannot accumulate technical records wins each medal by luck, not by repetition.

Alongside that runs a flattening of events. Modern football erased the pure winger, once every wide midfielder was taught to drift inside. Vietnamese swimming is following a similar arc: resources are poured into the events that once produced medals, while the remaining distances empty out. Diversity under the water needs no split sheet to be seen, but it will vanish before anyone records it.

Media platforms pay to secure football rights, and most are losing money, repeating the mistake pay television made twenty years ago. A split database costs less than one percent of that money, yet nobody buys it because nobody sees its value. The cheapest things are usually the most mispriced.

Takeaway

In the summer of 2026, when stands were empty and meets were cancelled one after another, I made the podcast “Running in Silence”. The episode recorded at five in the morning had no pictures, no results, no scoreboard. Only breathing, footsteps on a bridge deck, and a swimmer... a runner... describing how he felt. That episode was heard more widely than any of my number-heavy reports.

The empty stands of 2026 taught me that sport is never silent, it only changes its voice. Vietnamese swimming is the same. The sport is saying a great deal, through splits, through turn counts, through stroke rate. We simply have not opened the notebook.

The work required is smaller than it looks. One open database, logging the splits of every national-team swimmer for the next ten years, published after each meet, enough that the next generation of coaches need not start from zero. Vietnam's next swimming medal will be decided in a notebook before it is decided under the water. And when the split sheet reaches the journalist's hand, the last person to benefit is the swimmer.
