Vietnamese Athletics and the Data Gap: A Record Without a Wind Reading Cannot Be Verified

At a national championship men's 100m final, the electronic scoreboard showed exactly one line of information: the time. No wind reading. No reaction time. No 30m or 60m splits. No note on humidity or track temperature. The crowd roared, and ten minutes later a photo of the scoreboard had spread through every running group in the country.

I stayed until the stadium lights went out. An empty stadium does not make me lonely, because data is the echo of thousands of people.

What I want to raise here is not whether one athlete ran fast or slow that evening. It sits somewhere else: we are building a national athletics programme on numbers that cannot be verified, and almost nobody seems uneasy about it.

After more than twenty years in this trade, from editing a magazine devoted to running through SEA Games and international meets, I picked up one habit: before believing a performance, ask how it was measured.

In mature athletics nations, a race is a data package. World Athletics requires wind speed to be measured by a properly placed anemometer beside the track, and a mark can only be ratified as a record when the tailwind does not exceed +2.0 m/s in the 100m, 200m, long jump and triple jump. The same athlete, the same feeling of running really well, but 10.50 seconds with a +1.9 m/s tailwind and 10.50 seconds into a -1.2 m/s headwind are two different truths about ability.

In Vietnam, most result sheets stop at time and placing. Organisers do their job properly: they determine who finished first. Everything else, the part that turns a result into data comparable across years, is left blank.

Nguyen Thi Oanh is the clearest example of both sides of the problem. At SEA Games 31 in Hanoi in May 2026 she won three gold medals in the 1500m, 5000m and 3000m steeplechase, a workload few female runners in the region would even enter. But when I went looking for the detailed data of those three races to see how she distributed her speed between the first and the last, all I had were three final times. No lap splits. No 400m rhythm. One of the most impressive physical performances in Southeast Asian athletics, and we do not hold enough data to retell it properly.

A minimum data sheet for a 100m race needs nine fields: wind speed, temperature, humidity, reaction time, 30m split, 60m split, lane, starter's name, and the time. At a national championship we currently have two of them.

That shortfall is not harmless. Without a wind column, every comparison across eras becomes a matter of feeling. A national record set in 2026 in rain, into a headwind, on an old track surface cannot be placed beside an equivalent mark from 2026 on a new synthetic track in ideal conditions. Fans still argue over who was faster, on faith, because nobody ever gave them the tools to answer with data.

For coaches, the shortfall removes the ability to diagnose. A 400m runner whose times have flatlined for three months may be breaking down in the first 200m, or in the last 100m, or in both. Without splits, those two very different causes look identical on a results sheet. I have watched an athlete told to add endurance work when the raw numbers pointed to top-end speed out of the blocks. A wrong training plan, built on an empty dataset.

And at the far end, it shuts the door to the international market. No scout evaluates a sprinter on final time alone. They want reaction time, peak velocity, the ability to hold speed through the 60-80m segment. Without data, Vietnamese athletes walk into that market empty-handed.

When numbers speak, all I have to do is listen. Here, we are sitting in a silent room, and sometimes we mistake that silence for peace.

At this point I have to argue against myself. In football, distance covered and sprint counts are packaged as effort metrics, but ineffective running also produces beautiful numbers. A midfielder who covers 12km in a match may be the player who ran the most and also the player pulled out of position the most. The metric measures activity, not value.

Athletics has the same trap. If we simply add columns and numbers without agreeing on measurement methods, we create something worse than a shortage: data that looks scientific but cannot be compared. A 30m split taken by a high-speed camera and one read by eye from the stands are two different things. If every province publishes to its own standard, we gain paper, not understanding.

The counter-intuitive point sits here. Vietnam's athletics problem is not a shortage of data. The data exists, in coaches' notebooks, in personal spreadsheets, in the memories of the people who teach the sport. What is missing is a shared standard and a place to publish it. Distance never lies; we simply have not been patient enough to listen.

One more thing. Do not turn data into a disciplinary tool. If every published metric is used to conclude that this athlete is lazy and that one is weak, coaches will learn to hide their numbers, and we are back at the starting line. Data only lives when it is used to understand, not to judge.

Every number is a confession the race cannot deny, but only when someone takes the trouble to write it down properly.

What I want to see next season is not a new national record. I want to see wind speed printed on the results sheet. I want to see 30m splits in men's and women's 100m finals. I want to see the anemometer's name and its position, as international meets have done for decades. Small jobs, low cost, and they change how an entire athletics nation tells its own story.

I do not believe in luck; I believe in what has been repeated enough times. And to know that something has been repeated, someone first has to record it.
