Vietnamese Athletics Lacks a Measurement System, Not Athletes

At a national youth meet in Hai Phong, I stood at the finish line of the men's 100 metres with three hand-held stopwatches in three different hands. Three numbers: 10.78 — 10.85 — 10.91. No wind gauge. No finish-line camera. The organisers announced a single time, and that time went into the minutes, into the record book, into the story of a seventeen-year-old boy the whole athletics community would talk about for months.

I am not saying anyone cheated. I am talking about the measurement chain. When three devices give three results, the published figure is an average of belief. In a sport where everything is decided by hundredths of a second, an average of belief is a very weak foundation for anything.

"The day football stopped, I started counting every stride again." I wrote that line in April 2026, when the V.League shut down and I spent four months re-reviewing 2,300 matches. Football taught me to trace a number back to its root. Athletics taught me that most numbers in Vietnam have never been traced at all.

In 2026 I joined Runner's World magazine and wrote about running for a long stretch of my career. In 2026 I became a data consultant for Hai Phong FC, and there I learned the biggest lesson of my working life: the right metric can open a door for a human being. Midfielder Vu Minh Hieu averaged a PPDA of 6.8 that year — the best in the academy — but was overlooked because of his small frame. I carried the spreadsheet into the meeting room, and coach Truong Viet Hoang gave him a chance. Against Ha Noi FC on matchday 17, Minh Hieu won the ball 14 times, provided one assist, and Hai Phong won 2-1. Hai Phong taught me: the star is not on the shirt, it is in the index.

In the summer of 2026 I used qualifying data to say Germany would be eliminated in the group stage: an average PPDA of 9.2, slow build-up speed, xG only mid-table. On the night of 27 June 2026, Germany lost 0-2 to South Korea despite 26 shots and 1.5 xG. I did not see Germany lose. I saw numbers that do not know how to lie.

Football and athletics differ on one methodologically fatal point. Football is a large-sample sport: a 30-match season, thousands of touches per player, and the noise cancels itself out. Athletics is a tiny-sample sport: in a year, an elite athlete races only a handful of meaningful times, and an entire career can fit into fifteen starts. When the sample is that small, the quality of the record stops being a side issue — it becomes the entire story.

An internationally compliant athletics record needs six layers: the finishing time; the conditions, meaning wind speed, altitude, temperature and track type; the splits; the reaction time; the equipment, meaning shoe model and sole thickness; and the ratification process including doping control. Strip away the first five and keep only the first, and we are left with a number that cannot be verified — which is an anecdote, not a performance.

Layer one — the finishing time — is the only layer almost always recorded in Vietnam, and it is also the least informative. It does not tell you how the athlete ran, only where he finished. Look at a national championship results sheet: name, bib, time. Nothing else. The fault is not with the organisers; the fault is that nobody has yet demanded to see anything else.

Layer two — the conditions — is the most neglected. World Athletics rules state that in sprint, hurdle, long jump and triple jump events, a record is only recognised when the tailwind component does not exceed 2.0 metres per second. At major domestic meets the wind gauge is present; at many provincial and youth meets it is not, and wind readings are rarely published alongside results for the public. Temperature is the same story. A meet in Hai Phong in July can be run in 34-degree heat, and a time recorded in those conditions cannot be placed next to a time run at 22 degrees without a note. In Vietnam, that note barely exists.

Layer three — the splits — is where the real story lives. An 800-metre runner who passes 400 metres in 52 seconds and finishes in 2 minutes 12 seconds has run the second lap in 80 seconds. The results sheet says only "2:12". A reader concludes: poor performance. Someone with splits concludes: wrong pace distribution, and this is fixable in eight weeks. Those two conclusions lead to two entirely different coaching decisions, and only one of them has a data basis. When Nguyen Thi Oanh finishes a middle-distance race at the SEA Games, what I most want to know is not her overall time but how many seconds faster her final 1,000 metres were than her first — because that is what separates a tactically aware racer from someone who merely runs fast. With Nguyen Thi Huyen in the 400 metres hurdles, the valuable metric sits in the 200-to-300-metre segment, where hurdling technique begins to break down under the weight of lactic acid. With Nguyen Van Lai in the 5,000 metres and 10,000 metres, what is needed is the pace per kilometre. We have the final results, and we do not have everything else.

Layer four — equipment. Since 2026, World Athletics has tightened its competition shoe regulations, capping sole thickness for road shoes and introducing an approval mechanism for new models. The reason is simple: when a shoe can save a few per cent of energy, a personal best no longer belongs purely to the legs. A Vietnamese athlete who breaks a personal record in a carbon-plated shoe deserves credit for it, and also deserves a footnote. Nobody did anything wrong. It is simply that part of the number belongs to the shoe.

Layer five — ratification. A national record is a legal document, not a figure on a scoreboard. It requires automatic timing, official supervision, doping paperwork and a valid wind reading. A process that is not public produces records that cannot be verified, and a record that cannot be verified cannot be used to compare with anyone.

Layer six — sample size. In 2026, when football stopped, I reviewed 2,300 matches to build a pressure index combining PPDA, defensive distance and pressing speed. Teams with a PPDA below 8.5 averaged 1.8 points per match, clearly above the rest. I believe in that model because it rests on a large sample. But the same model taught me that a single 10.80-second run says nothing about an athlete; three consecutive seasons around 10.9 is a signal. A season is a confession of tactics — but only when there is a season to read.

There is a counter-argument I have to raise myself before anyone raises it for me. If Vietnam upgraded its entire measurement system, would there be more medals? Nobody can prove that. Correlation is not causation; a country can buy expensive automatic timing equipment and still finish sixth. The cost is real: a compliant automatic timing system for every provincial youth meet costs money that organisers could spend on coaches' salaries. If forced to choose between a good coach and a finish-line camera, I choose the good coach — for the first ten years.

But the real bottleneck is probably competition density. A Vietnamese sprinter may race all-out roughly eight to ten times a year; her Jamaican counterpart races twice as often. Fewer starts means less data, fewer chances to clash with strong opponents, and fewer opportunities to learn how to run a heat and then a final on the same day. Numbers are a mirror. Most of the market looks into it and sees only itself. I also have to be honest about my own limits: my 2,300-match model is a football model. It does not transfer to the track. The figure of 1.8 points per match says nothing about an 800-metre runner.

What I can state with certainty is much narrower: bad data leads to bad decisions. A hand time padded by two tenths of a second can keep a young athlete off a national training squad, and a place lost at seventeen rarely comes back. Timing equipment does not create medals. It only prevents medals from being dropped because of a wrong number.

A world medal or an Olympic final place is beyond Vietnamese athletics in the next few years, and saying otherwise is self-deception. But the 33rd SEA Games in Thailand, scheduled to open in December 2026, is an observable milestone. The signal I will track is not the medal count, but whether organisers and federations publish splits and wind readings for every running event. People call me a data monk. A monk does not need a cathedral — only the truth. And if next season a seventeen-year-old boy in Hai Phong runs 10.75 seconds, will we have enough data to believe him, or only enough to tell a nice story?
