Vietnamese Athletics and the Data Gap: Medals Without a Logbook

In September 2026, at the national athletics championships at My Dinh Stadium, I sat in the technical area with a notebook and a laptop. A female athlete crossed the line in the 400-metre hurdles. I noted the time that had just been announced, then opened my browser to look up her personal best across seasons. Nothing. I tried the federation's page, tried athletics forums, tried even the closed groups of the coaching world. Not a single table compiled the full four-year competitive journey of that athlete. I knew she had run, had won, had lost, but none of it existed anywhere as searchable data. That night I sat alone and realised something: the biggest problem in Vietnamese athletics is not on the track. I have worked as an athletics commentator for five years, and before that spent nearly seventeen years observing the sports industry from various angles. In that time, I learned something few people say out loud: an athlete's mark only has analytical value when it is placed beside that same athlete's marks from previous competitions. A 53-second run in the 400-metre hurdles is good or not good not because of the absolute number, but because of whether she had previously run 54 seconds or 52 seconds. Without past data, people can only praise or criticise by feel. Vietnamese athletics has had moments the whole country remembers. Nguyen Thi Oanh with SEA Games golds in the 1500 metres, the 3000-metre steeplechase and the 5000 metres. Nguyen Thi Huyen in the 400 metres and 400-metre hurdles. Le Tu Chinh with her speed in the sprints. Bui Thi Thu Ha in long-distance marathons. Those names are mentioned in the media, celebrated after every Games, and then fall silent until the next season. The problem lies here: between two remembered moments, no system records the journey. A Vietnamese athlete's marks usually exist only in the organisers' competition records, in a few short news lines, and in the memory of the coach. There is no national database that allows one to look up personal marks across years, compare seasons, or track the progress of a generation of athletes. Years ago, I heard a coach say in the locker room that he did not need data, he only needed to watch the athlete run. Now I tell that story back using the very numbers he was missing. This may sound like a dry technical matter. But it decides almost everything. To analyse a track-and-field athlete, I need at least four layers of data. The foundation layer is the personal-best curve, that is, how the best mark has changed year by year, to know which stage of a career the athlete is in. Layered on top is current-season form, to set against the personal best when judging. Then comes competition structure and the qualifying mechanism, to know the athlete's realistic target. And finally the competition context, including wind, altitude and track conditions, to adjust the value of the number. In Vietnam, I usually have only the foundation layer in fragmented form, and almost never all four. Take the personal-best curve. A 400-metre hurdler at twenty-two usually has two to three more years to peak. If I know she improved from 56 seconds to 54 seconds over three years, I can predict she still has room to go below 53. But if I see only a single 54-second run, I do not know whether that is her peak or just a point on a still-steep curve. The same number, two completely opposite conclusions. The problem is more serious at national-team level. As a SEA Games approaches, the coaching staff must decide who gets investment, who competes in which event, and what the points-accumulation strategy is. Those decisions need data cross-referenced against regional rivals, including the athletics programmes of Thailand, the Philippines, Indonesia and Malaysia. But if our own data is incomplete, then comparing with others is only guesswork. I once took part in a technical meeting before a major competition. On the table were a few printed sheets of rivals' marks, typed by hand from scattered search results. No one dared confirm those numbers were correct, because no source had been verified. The entire analytical meeting rested on data its own users did not trust. That is a paradox: we have athletes, we have marks, we have medals, but we lack the glue to turn them into knowledge. In athletics, where marks are measured in hundredths of a second, imprecise data is not a minor detail. It is the difference between a place in the final and a ticket home. In 2026, when the pandemic closed the tracks, I opened Excel and began doing what a federation should have done long ago. I rewatched hundreds of competitions and recordings of international women's athletics events from 2026 to 2026, noting every small change in the technique and tactics of female athletes. I recorded more than twenty thousand rows of data. After nine months, I held a long-term picture that no single news report could provide. What I learned was not a technical secret, but the discipline of record-keeping. When you have an athlete's data across many seasons, you begin to see things invisible to someone watching a single race. You see when an athlete starts to slow in the closing stretch, you see changes in how effort is distributed across laps, you see injury signals when marks suddenly plateau. Without data, all of that disappears, and people are left only with emotional stories. What is striking is that the strong athletics nations in the region have done this for a long time. Thailand has an athlete-data system updated at every meet, letting it calculate precisely how many points are needed to earn an Olympic or Asian Games place. Japan builds performance records from the high-school level, and those records follow athletes throughout their careers. When a Japanese athlete steps onto an international track, their coaching staff already know exactly how many times she has run, under what conditions, and what the trend has been over the past three years. That preparation is not in the legs; it is in the information. There is a widespread belief I have met for many years: Vietnamese athletics lacks results because Vietnamese bodies are inferior to those of other nations. That belief sounds very reasonable, and it is repeated often enough to become the default. But placed beside the data, it collapses quickly. Kenyans do not run faster because of their race. They run faster because an entire system is built around running, from high-altitude training camps to nutrition, to recovery, to a culture of recording and comparing marks from childhood. What decides is not in the calf muscles; it is in the notebook. And Vietnam can have that notebook, if it wants one. Here I must say plainly something the commentary trade rarely admits: Vietnamese sports media is nurturing the data gap instead of fixing it. After every Games, we have hundreds of articles praising extraordinary resilience and a will of steel, but almost none analysing why that athlete ran faster than three months ago. Such flowery words are easy to write and easy to love, but they obscure the very mechanisms fans need to understand. The commercial value of an athletics programme is built from stories, but sustainable stories must be built from data. An athlete with a clear personal-best curve will attract sponsors better than one with a single medal and a few news lines. Sponsors do not buy a single night's emotion; they buy a journey that can be tracked, measured and retold over years. When data does not exist, that journey cannot be sold, and athletics lives forever on scattered moments. I do not write this to blame anyone. I write because I believe Vietnamese athletics stands before a rare opportunity: we have athletes, we have tracks, we have audiences, and now we lack only a habit. The habit of recording. Recording marks, recording competition dates, recording track conditions, recording every run of every athlete from their junior days. A notebook will not make anyone run faster in a single morning. But a notebook kept for ten years will tell us who is improving, who is stagnating, and who deserves our trust. When a Vietnamese female athlete crosses the line on an international track, she deserves a journey recorded in full, so those who follow can learn from it and carry on. Athletics does not need more cheering. It needs to be recorded through the eyes of someone who works with data. And I will keep recording, until that notebook is no longer mine alone.
