The Notebook and the Track: Vietnam's Missing Women's Athletics Data

At five forty in the morning, at a provincial stadium on Vietnam's central coast, twelve girls aged thirteen to sixteen line up at the start of the loop track. Their coach stands in the middle of the infield, a faded stopwatch in his left hand and a dog-eared squared notebook in his right. Each rep ends, he reads the number aloud, the girl nods, and he bends down to write it in ballpoint pen. The session runs six reps of two hundred metres. Forty minutes. Seventy-two numbers recorded.

No electronic timing system. No wind gauge. No split data. No camera in the corner of the ground. And almost certainly, nobody outside that fence has ever read the notebook.

I sat on the concrete terrace for the whole morning, and what kept me there was not the speed of the girls but the notebook. It probably holds several thousand handwritten times accumulated across many seasons. Those numbers decide who gets called up to the national youth team, who qualifies for a nutrition allowance, who is allowed to keep studying inside the sports system, and who leaves the track before her eighteenth birthday. A provincial ball has no league table, yet it is what tells me where I belong. The notebook is the same. It exists in no database in world athletics, yet it is writing the fate of an entire generation of Vietnamese female athletes.

Vietnamese women's athletics runs around one big target: the SEA Games. Behind that target sits a network of provincial talent schools, national training centres, the national championship and an age-group youth circuit. A typical female athlete starts at a provincial talent school around twelve, is picked for the national youth team a few years later, and enters the senior priority group in her early twenties. Vietnam's traditional regional strengths sit in the middle distances: four hundred metres, four hundred metre hurdles, eight hundred metres, fifteen hundred metres, three thousand metre steeplechase and the four by four hundred relay.

The regional competition has changed. Thailand and the Philippines have invested heavily in sprint and middle-distance events, Indonesia holds an edge in some endurance events, and Malaysia keeps a stable sprint group. The medals Vietnam once assumed were in the bag now have to be won on merit rather than through rivals' absence. That pressure lands squarely on a small group of priority female athletes, and it is exactly why the data question matters more than it is usually granted.

There is a gap few people mention: the way we record results. At most domestic meets, the published result lists a name, a province and a final time. Occasionally it is an A4 sheet pinned to a noticeboard. That is enough for a ranking, but not enough for anyone who wants to understand why an athlete got faster or slower.

Since 2026, a new variable has walked onto the track without appearing in any results sheet: the shoe. Spiked shoes with carbon plates and super-light foams arrived, and a number of independent studies published between 2026 and 2026 recorded energy savings of roughly two to four percent in long-distance events. Four percent sounds small until you remember that over five thousand metres, four percent of fifteen minutes is thirty-six seconds. Thirty-six seconds is the gap between a final and a heat exit.

In Vietnam, that technological gift is distributed very unevenly. National team athletes have access. Provincial athletes, especially in provinces where athletics is not a priority sport, often run in shoes bought on a tight budget. So when someone compares a provincial girl's 2026 time with a national team athlete's 2026 time, they are comparing two fundamentally different things. A personal best only means something when we know which shoe produced it, on which surface, in which wind conditions, and in Vietnam those three facts almost never appear together.

SEA Games 32 in Phnom Penh in May 2026 saw Nguyen Thi Oanh win the three thousand metre steeplechase and then, only minutes later, win the fifteen hundred metres. The story has been retold many times as a symbol of willpower. It is that. But from a physiological standpoint it is also a gamble that very few female athletes in the world are permitted to take. Two maximal races in one session mean the body must process two near-consecutive drawdowns of glycogen stores with essentially zero recovery time.

At national level, the pattern repeats more often than people realise. Across a three-day national championship, it is not rare for a female athlete to be entered in four or five events, individual races and relay legs included. At many provincial teams, one physiotherapist covers dozens of athletes in the same competition week. Competition density, not training load on the track, is what takes the most from the body of a Vietnamese female athlete. The Achilles tendon cases, the hamstring strains, the foot bone pain I have watched at youth meets rarely come from one hard session. They come from the third consecutive competition week. No medical staff can make up for a calendar someone else set.

Anyone who has seen the results sheet of an international athletics meet will notice something entirely different: splits at each checkpoint, reaction time off the blocks, wind speed for events under two hundred metres, and the count of invalid starts. That data lets an analyst see where an athlete is running wrong, rather than merely whether she ran fast or slow. Without split data, every conclusion about a young athlete is a guess dressed up in emotion. A girl who runs four hundred metres in fifty-six point eight seconds may be next season's breakthrough, or she may have already hit her ceiling. Those two scenarios point to completely different training plans, and we have no way to tell them apart without knowing her first two hundred metres.

In the summer of 2026, when almost the entire calendar was suspended by the pandemic, I sat down and hand-timed more than forty old races from video, hunting for a pattern in how athletes distribute their effort. The work taught me something humbling: hand-timing off a screen is off by at least two to three tenths of a second, and the error is not consistent between reps. That is why human-eye data cannot be used to evaluate an athlete, even though it is perfectly good for inspiring a crowd. Those are two different jobs, and we are using the tool of the first for the second.

For events that reach the world stage, the international federation's ranking system forces athletes to accumulate points at recognised meets. That means a Vietnamese female athlete chasing a major championship slot has to race abroad more often, precisely when her body should be loading for a domestic peak. Which meet, in which month, is a strategic problem rather than a line in a training plan. And around it grows a kind of rumour that is very hard to verify: fast times from internal time trials, circulated as though they were records. A mark only counts when it is produced in a competition with official officials, compliant equipment and valid ratification conditions. Other numbers can be used as encouragement, but not to allocate slots, allowances or rankings.

One aspect rarely discussed is doping control at national level. Female athletes must file whereabouts information, submit to out-of-competition testing, and know the prohibited list, which includes ordinary cold medicines. For a nineteen-year-old from a province, this is not technically difficult but educationally difficult. A small mistake on a medication declaration can erase four years of training. This is not a story about cheating; it is a real occupational risk, and the only way to manage it is to properly inform both athletes and their direct managers.

At the coaching level, the clearest technology gap is not in shoes. It is in periodisation. Some centres already use training-load software and speed sensors; most provincial teams still rely on experience and instinct. The instinct of a good coach is a genuine asset, but it cannot be handed to a successor as data, and it cannot be checked when results run against expectation. This is the kind of gap that makes a sport depend on a few exceptional individuals rather than on a system.

One reality I have recorded over years of sitting at youth meets: the number of female athletes in the four hundred and eight hundred metre groups drops sharply after each season. Many seventeen-year-olds with good physical capacity stop to focus on their school-leaving exams, or because the financial support is not enough to live on. Those who stay tend to have a more favourable provincial environment, a university place, or a patient coach alongside them. Put another way, the women's track in Vietnam is not narrow at the entrance. It is narrow at the eighteen-year-old turn.

Most of the money in high-performance sport flows toward what can be seen: medals, bonuses, welcome ceremonies, magazine covers. That flow is reasonable, because it feeds the emotion of the audience. But placed side by side, I would argue that what blocks the growth of Vietnamese women's athletics sits in the expenses nobody wants to pay: electronic timing good enough for every youth meet, centrally archived competition data, a physiotherapy room with a named person responsible, and a record keeper who knows exactly what she is recording.

I have heard a familiar explanation: women's athletics has no audience. I think the opposite. It has no audience partly because we have never given the audience enough information to understand a race. A football match has dozens of metrics on screen. An eight hundred metre race can be just as compelling, if viewers know how much faster than her personal best she went through the first two hundred, and how much that will cost her over the last two hundred. The biggest hidden cost in Vietnamese women's athletics lies in the expenses nobody wants to pay, and those expenses are far cheaper than one overseas training camp.

The squared notebook at that coastal stadium is still being written in every morning. What I am waiting for is not another medal, but the day someone digitises it, so those numbers no longer depend on one person's memory. Glory does not come from the stadium lights, but from the women who dare to dream. If, ten years from now, somebody sits down to open today's data, I want them to see more than a single line of a final result.
