London 2026 and the Data Gap of Vietnamese Sport

On the opening night of the London 2026 Olympics, July 27, the Olympic Stadium in east London lit up. The mixed zone reserved for the press was packed. Major reporters queued for the track and field stars to walk past. A few metres away, a young athlete from the Vietnamese delegation sat down on the floor, took off her shoes, and checked her laces again. No camera turned toward her. No one recorded how long she warmed up, what her heart rate was, how long her rest intervals between heats lasted. When she stepped onto the track, the world saw only a number flickering on a screen. Everything that led to that number vanished without a trace.

I recall that moment not to speak of a defeat. I recall it to speak of something else, rarely mentioned: a sport system's capacity to remember.

London 2026 ran from July 27 to August 12, 2026, gathering more than ten thousand athletes from more than two hundred countries and territories. Vietnam's delegation appeared with a thin roster spread across a few sports: athletics, weightlifting, badminton, swimming, shooting. That Olympic cycle closed without any medal for Vietnamese sport.

That is the result. What interests me lies in the submerged part: after each time Vietnam's delegation steps onto the international stage, what do we keep for the next time?

In 2026, I had the chance to sit in the technical area of a domestic athletics meet. Organizers recorded times with hand-held stopwatches and wrote them in a notebook. The only video came from a coach's phone. When the meet ended, no one compiled it into a searchable dataset. Athletes left carrying their personal bests and their coach's words. Analysts left carrying memories.

Three years later, in 2026, a young coach asked me whether I had any records on an athlete who had competed at that meet. I searched. There was nothing but a few blurry photos and a printed results sheet. We had spent time, money, and the effort of many people only to lose the one thing that could teach the next generation: data.

Data is not a dry number. Data is memory that can be queried. That is the difference between a sport system that learns from itself and one that restarts from zero every season.

Looking at the London 2026 track, the gap between Vietnamese athletes and the leading group is usually explained by talent, nutrition, and training conditions. Those explanations are partly right. But they overlook a lower layer: the capacity to observe and to retain.

Take a middle-distance event. Athlete A runs the heats with a personal best. Athlete B runs slower but finishes with steadier pacing across each two-hundred-metre split. With only a results sheet, A ranks higher. With video and split times, one sees that B is improving in a sustainable way. The problem is that most of those split-time records do not exist in our archives. So every comparison halts at the final number.

I once read a technical report by the International Association of Athletics Federations on analysis work at international youth meets. The notable part was not high technology, but a simple habit: record everything, including failures, to the same standard. Ten years later, that standard becomes an asset.

In basketball, the gap is even clearer. Vietnamese basketball around 2026 was played mostly indoors, in a handful of regional tournaments. A single game holds so much information: shooting percentages by court position, turnovers under pressure, the efficiency of each lineup on the floor. Yet almost no one recorded enough to answer a simple question: did this team win because of its defence or because of luck?

As a result, decisions about personnel and tactics often rest on feeling. A good coach can read a game with the eye. But the human eye cannot retain eighteen games in a season. Meanwhile, a decent dataset can answer, after eighteen games, that this team concedes most in the final four minutes of the third quarter.

I do not tell the data story to glorify technology. I tell it because I believe the opposite of a common belief: we fail on the big stage not for lack of money, but for lack of the patient habit of recording from the smallest days.

And here is the most counterintuitive point: the data gap is not filled with money. It is filled with discipline. Expensive analysis software is worthless if no one sits down after the game to tag each possession. Meanwhile, a serious notebook, a fixed camera behind the goal, and a weekly review session create an asset that compounds over the years. I have seen youth football groups in difficult regions keep that habit, while better-resourced teams let it slip.

From here a question about youth development arises. We are often impatient with a young player: we promote him to the first team too early, pushing him into the pace of adult competition before his body has matured. That impatience also shows in how we treat data. We want results now, we want the medal in front of us, so we skip the archiving work that brings no immediate glory.

Yet it is precisely that archiving work that protects young players. It allows us to answer: after how many minutes of real competition does his stamina begin to drop, in which movement did he get injured, in which skill did he improve month by month. Without data, every decision about an eighteen-year-old is a guess. And a guess at that age can ruin an entire career.

I have often blamed myself for articles written too fast. In 2026, I mispronounced a young player's name live on air, three times in a row. The lesson I drew was not about remembering names, but about understanding that speed is the enemy of accuracy. In my work I then set a three-touch rule for myself: watch the tape at least three times, read the subject's name aloud, cross-check figures against the original source. That rule was born from a moment when the whole of social media corrected me.

For a sport system, that rule multiplies into a collective habit. No one rewrites history if no one is willing to record history.

The track and the pitch are not far apart; few people are simply willing to run a full lap to see it. The same athlete, the same training session: someone who looks only at results sees a number; someone who records every lap sees a process. Vietnamese sport in the 2026 period lacked the second.

I do not believe Vietnamese sport lacks talent. I believe we have not finished building the grammar to retell our own story. Every time I stumble on the track, I hear another heartbeat falling into rhythm with mine. But that heartbeat is only recorded if someone, right then, sits down and writes.

People do not run to leave someone behind, but to see how far they can go together. And going together, in the most lasting sense, begins with remembering where we have been.
