A Track Without Metrics: The Data Void Behind Vietnam's Athletics Medals

A Track Without Metrics: The Data Void Behind Vietnam's Athletics Medals

In May 2026, at Morodok Techo Stadium in Phnom Penh, I sat seven rows from the piste, close enough to hear spikes bite the track, far enough not to be swept up in the roar. A Vietnamese woman was running the 400 metres. As she entered the final bend, I did what I have done for twenty years: I opened my stopwatch and tried to record each 100-metre split.

I caught the first segment. By the second, my eye slipped off the line. By the third, I gave up. Not from laziness — from having nothing to measure against. After the finish, the organisers published exactly one number: the final time. No splits, no peak velocity, no reaction time, no pacing distribution. An athlete who runs 52 seconds by exploding over the last 200 metres and one who runs 52 seconds by flying out and fading over the last 80 are two entirely different stories. On the results sheet, they are identical.

That was the moment I realised what I had suspected for years: we talk endlessly about performance, but we have almost no data to understand it. Records are only shadows; it is the human being who is the track.

Vietnam is a genuine force at the SEA Games in athletics. Nguyễn Thị Oanh over 1,500m, 3,000m steeplechase and 5,000m; Nguyễn Thị Huyền over 400m and 400m hurdles; Nguyễn Văn Lai at distance; Lê Tú Chinh in the sprints. Step outside the SEA Games, however, and the picture changes fast. At Asian level and in Olympic qualifying, the gap remains large — and, crucially, we rarely know exactly where that gap sits. Is it top speed? Pacing tolerance? Hurdle technique? Aerobic base? Race strategy?

No one can answer systematically, because data is missing at nearly every layer. While the world today measures a sprinter by dozens of variables per race — ground contact force, contact time, stride frequency, stride length, reaction time, ten-metre speed distribution — most public information about Vietnamese athletes stops at one line: name, mark, placing.

I map an athlete across nine layers. Layer one, performance and marks: a mark only means something against a reference system, yet we rarely publish wind readings, surface, temperature or humidity. Layer two, athlete condition: an athlete is a curve, not a static number. Personal-best progression by year reveals ascent, peak or decline. We keep that in coaches' notebooks, never in public records. The most dangerous pattern for an analyst is an "abnormal explosion" — an athlete flat for three years who suddenly leaps. In well-documented systems, that triggers cross-validation. Here, with no historical curve, there is nothing to check and nothing to protect. Injury history, meanwhile, is treated as an internal matter; without a recovery log, re-injury is only a matter of time. Layer three, competition structure and qualification: standards, world-ranking points, national trials — each with its own physical cost, and here the trial route dominates, limiting international exposure and, in turn, limiting data. Layer four, event landscape: Vietnam is strong in some distance events regionally but belongs to no continental top tier, and we have not answered whether to concentrate on a few events or spread out for regional medals. Layer five, rules and anti-doping: compliance is an obligation; capacity is something else. Active capability requires a stable biological database per athlete, trained monitoring staff, and clear handling procedures. Here I refuse hasty conclusions, because the cost of a wrong call — accusation or exoneration — is too high for a human being. Layer six, training systems: we have diligent coaches, but modern systems need periodisation, sports science, recovery, measurement. I once visited a training group in central Vietnam. Simple facilities, few tools, but a coach with an astonishingly detailed notebook — every session, every drill, every post-run sensation. "I have no machine, but I have eyes and a notebook." That is the spirit of data even without its instruments. The problem is that these notebooks are scattered, unstandardised and undigitised; when the keeper retires, the knowledge retires with him. Layer seven, risk landscape: competitive, anti-doping, financial, eligibility, media, systemic. My rule is simple: when there is no data, do not default to "low risk". Silence is not safety. Layer eight, public narrative: athletes live inside stories others tell, and the public story runs far ahead of the underlying truth. A mark repeated three times is a thick truth; a mark achieved once in perfect conditions is a thin one. Layer nine, industry transmission: upstream talent development, midstream athletes and competitions, downstream media, commerce, representation. In Vietnam the chain is broken at several points, and the loop feeds itself: no attention means no investment in data; no data means no deep story to attract attention.

But I must argue against myself. There is a great temptation in analysis to believe data answers everything. It does not. I have watched many data-heavy athletics breakdowns end with a conclusion anyone in the stands already saw. Data becomes ritual rather than instrument. The opposite trap matters here too: with so little data, every conclusion is fragile — yet if we rush to collect everything, we fall into the trap of false complexity. What we need is not more data but the right data: three splits for a 400-metre race, a year-by-year PB curve per athlete, an injury log with dates, a competition conditions sheet listing wind, temperature and surface. That alone would change how we understand Vietnamese athletics.

And a third paradox: because data is missing, we read athletics emotionally rather than analytically. A win becomes a national symbol, a loss a moral tragedy. Emotion is not wrong — sport needs it, and I write with it — but emotion without data easily hardens into prejudice, and prejudice never helps an athlete. I remember a late-night call from an athlete after a failed competition, saying what no one says by daylight: the injury was not fully healed, the programme had been disrupted by a lack of training grounds, and the athlete did not know what specifically to change. No dataset gave me the answer. But that call taught me that when data is missing, it is replaced by whispers in the dark — and a writer who does not listen to those whispers will only produce soulless numbers.

Back in Phnom Penh, I went down to the athletes' area and found a woman who had just raced a middle-distance event. She won no medal. On the results sheet she was a faint line. She told me she had changed training grounds three times in one year; she paid for some supplementary sessions herself; and she kept a small notebook recording every run since secondary school. That notebook, she said, was her second coach.

There are athletes who never reach the finish line, yet keep running forever in my memory.

I asked her the question I always ask, the one many in the trade consider naive: "Do you know your speed over the last 200 metres?" She looked at me, surprised, and shook her head. No one had measured it. No one had told her that number mattered. That is when I understood the core point of this piece: Vietnam's biggest athletics problem is not a lack of talent; it is a lack of memory. We forget too fast — old marks, old injuries, old sessions, athletes who almost made it. When collective memory is erased, every generation starts again from zero.

A strong athletics nation is measured not only in medals but in its ability to transmit memory across generations. In countries with long track traditions, a sixteen-year-old can look up what predecessors ran, trained and injured at that age. Here, the network is cut. Every record by a junior is celebrated for three days and then goes silent; no curve, no context, no baseline. When that junior is twenty-five and no longer breaking records, no one can explain why.

I am a writer, not a policymaker, so I speak only to what writers can do. First: every article about a track athlete should contain at least one contextual fact — not "she won gold", but "she won gold in X, in wind Y, Z seconds faster than a year ago". Second: standardise the vocabulary — PB, SB, split, qualifying standard, national record — so information becomes comparable. Third: tell the failures, not only the victories. An athlete who dropped out of a distance race, one who changed events after injury, a generation that won no continental medals — those stories carry richer data than a medal, because they mark the fracture, and the fracture is where the work begins.

Athletics and life share one thing: everyone has a finish line, but few run the right route. Our job is not to grade that route but to record it — carefully, honestly, with all the necessary numbers and all the sighs numbers cannot express.

If there is one thing I want to leave behind, it is this: Vietnamese athletics does not need more applause; it needs more pages of notes. Every split saved is a piece of the past kept. Every PB curve drawn is one less restart from zero. Every failure carefully told is one generation less forgotten. I do not dream of a grand data centre. I dream of the day a girl in Liên Chiểu, Đà Nẵng, records her speed over the last 200 metres — and knows that this small number will not be forgotten.

And you: when did you last remember exactly how a Vietnamese track athlete changed from year to year?
