The Track and the Ledger: Investigating the Money Flow in Vietnamese Athletics

In the results table of the international marathon in Da Nang last March, one line made me pause longer than any other. A female athlete finished with a time of 2 hours 38 minutes 14 seconds, an improvement of 8 minutes 47 seconds over her personal best recorded six months earlier. Over 42.195 km, that margin is not progress — it is a statement. And in the sport I follow, every statement must answer two questions: what produced it, and who paid for it?

I often ask: where did this money come from, and what did it do along the way? In this case, the answer was not on the track. It was in a training centre forty kilometres away, in a building few outsiders in the industry have ever entered. The strangest thing is never the error — it is the way people try to explain it. And over the past three months, I have heard enough explanations to understand that the real story is being pushed behind the podium.

The context of this story is not an individual. It is an entire system changing faster than its ability to control itself. Over the past decade, Vietnam's mass athletics scene has seen an unprecedented wave: the number of marathon races has grown from a handful of events a year to more than forty nationwide, with total registrations exceeding two hundred thousand entries each season. Each race brings in anywhere from a few billion to tens of billions of dong from entry fees, sponsorship and media rights. But when I traced the money flow of seventeen major races over the past two years, I found something: the share of money returning to the athletes themselves — through prize money, training support, medical care — has barely changed, and in some places has declined.

That is the starting point. An industry growing fast, while the value flowing back to the people who create it grows thinner. When the financial structure looks like this, the inevitable result is that performance pressure is pushed back onto athletes, while the matching resources are not pushed at the same speed.

Look at the concrete numbers. According to an annual report from a provincial federation I hold — an internal copy, not the public version — the total budget for the provincial athletics team in 2026 was 6.4 billion dong. Of that, 71% went to facilities, travel and event organisation; 19% to coaches' salaries and administration; and only 10% — about 640 million dong — went directly to nutrition, medical care and recovery support for athletes. Divided among forty athletes on the roster, each receives less than 16 million dong a year for the survival needs of an elite running career.

That 10% figure is the centre of every problem. A system that spends 90% on its apparatus but only 10% on the people who run will automatically create two kinds of pressure: athletes must find outside income to survive, and the apparatus must prove results to justify its own budget. When those two pressures meet, no villain is needed to produce a distorted outcome. A broken structure is enough.

I began cross-referencing performance data with financial data. The method was not complicated: take each athlete's best personal mark year by year, compare it with the actual support that athlete received in the same period. The result, across a sample of 38 athletes with clean data over four years, showed a correlation I did not expect: the coefficient between direct support and performance improvement was only 0.21 — essentially negligible. In other words, increasing money for athletes did not come with increasing performance in the short term, because most of the money never reached the right place, and what did reach them arrived too late for the training cycle.

But there was an exception group. The seven athletes with standout improvement during the survey period shared one common trait: they received private funding independent of the official system. This is the point I want readers to study carefully, because it breaks the simple narrative of "more money, better results." These seven did not receive more money than the rest from the state. They received less — but their money flow had a different feature: it arrived directly, at the right time, and was tied to a specific training plan rather than an evenly allocated budget.

That is where the story becomes more interesting than a financial report. Because if the most effective money flow lies outside the official system, the next question is: who controls that flow, and what do they gain?

I followed these seven cases for four months. Three of them led to the same sports management company based in Ho Chi Minh City, founded in 2026, with modest charter capital but a client list of the country's top marathon athletes. The contract between the company and the athletes, according to a copy I accessed, included a 30% share of all prize money and a 45% share of all personal endorsement deals. In some markets, that split is not unusual. But the notable point lay in another clause: ownership of the athlete's image and training data was fully transferred to the company for the duration of the contract, including the right to exploit biometric data and performance indicators.

This is where I, with my experience investigating money flows in sport, saw a familiar pattern. The training data of an elite marathon athlete — heart rate, heart-rate variability, pace distribution, energy expenditure, recovery markers — has enormous commercial value. It is sold to analytics platforms, to equipment makers, and in some cases to data companies serving the betting industry. I have written that live data supplied to betting companies is the darkest side effect of the digitalisation of sport, and this case is a concrete illustration. Athletes sign a contract to get training money. But what they actually hand over, which many do not realise, is control of their own body data for years.

I cross-checked this with three independent sources: a former company employee, a lawyer who has advised on sports contracts, and two athletes who signed similar contracts. All three confirmed the clause structure, though none agreed to reveal their identity. I kept one principle intact: safety is not about not being caught, but about never leaving a trace. Every piece of information in this article has been split into independent parts, cross-checked against original documents, and published only when at least two unrelated sources confirmed the same detail.

Back to the female athlete in Da Nang. She improved 8 minutes 47 seconds in six months. When I built a simple probability model based on the distribution of performance improvements among female athletes aged 26-30 in public international race data, the probability that someone improves by more than 8 minutes in half a year, under stable training and without major physiological change, fell at around 1.3%. That is not an impossible number. But it is low enough to force me to ask: what changed?

The answer, according to training records I accessed through a source inside the training centre, was a structural change: she moved from an evenly allocated programme to a high-volume programme combined with daily biometric monitoring, under a new coaching group. This group was funded by a private programme, not the federation budget. In other words, it was the outside money flow that produced the performance leap, not the official one.

The strangest thing is never the error — it is the way people try to explain it. In conversations with people in the industry, I heard two common explanations. The first: this result is the product of "spirit and individual effort." The second: it was "the luck of a beautiful day." Both ignore the only measurable variable — the change in support and monitoring structure. When a good result appears, the system tends to claim credit; when a difficult question appears, the system tends to push responsibility onto the individual. This is a pattern I have met in many places, and it is not specific to Vietnam.

But if it stopped there, this article would be an indictment, and indictments do not help anyone run faster. I want to spend the rest of it on something few in this debate admit: the legitimate part of the current system.

There is a practical reason local federations allocate budgets the way they do. Their revenue is unstable. Sponsorship often arrives per event, tied to a specific competition, and cannot be used to pay athletes long-term. Facilities are something that can be proven with images, with inaugurations, with reports — they are easier to sell to sponsors than a quiet nutrition subsidy for a runner no one knows by name. In an environment where every dong of budget must come with a political reason to exist, spending on the apparatus and facilities is administratively rational, even if athletically wrong.

That is why I do not blame any individual in this story. Structure produces behaviour. Changing behaviour without changing structure only produces beautiful stories that fade again. This is also why I am cautious about calls to "invest more in sport" that come without a mechanism to monitor the money flow. Money poured into a system without traceability will not produce sustainable results — it will only create another layer of intermediaries.

So what is the key point I draw after months of monitoring? The value of Vietnamese athletics is not in the number of medals, but in its ability to make transparent the money flowing through the sport. A sustainable athletics scene exists only when every dong spent on an athlete can be traced from source to destination, and when the data rights of the runners themselves are placed on equal footing with the commercial rights of the sponsors.

I often ask: where did this money come from, and what did it do along the way? For Vietnamese athletics, the current answer is: it passes through many layers, stops in many places, and the part that reaches the runner is the thinnest part. But that answer can change. All I do is connect the dots — and count how many people deliberately draw them wrong. The rest belongs to those with the power to change the map.

Over the next three months, I will keep tracking two things. First, the contract structure between sports management companies and marathon athletes, especially the data clauses — because this is where the future value of the sport is being priced without the runners themselves being asked. Second, the actual share of prize money reaching athletes in the coming marathon season, cross-checked against the figures published on event portals.

People tell me I exaggerate; I tell them to wait a few more years. Vietnamese athletics is at exactly the point Vietnamese football was a decade ago: a new wave of money, a new layer of intermediaries, and a new generation of athletes without the tools to protect themselves. How we handle this phase will decide whether, ten years from now, the country's best runs are produced by the system or by the luck of a few exceptional individuals.

I choose to believe we can do better. But belief is not data. And in my work, data always wins.
