ASIAD: Nguyen Thi Oanh, 25 Laps and the Heartbeats Nobody Hears

17:44. The runway at the southeastern corner of the ASIAD athletics stadium still holds the heat of the afternoon. The red rubber is dull under the late sun, and along the outer edge two plastic boxes of hand chalk sit misaligned — one closed, one left open. That small detail tells me the last user had not put the lid back on. Which means she is still out there, with one more jump left in her head.

That is Vu Thi Ngoc Ha. Thirty metres away, Nguyen Thi Huong is finishing her last warm-up drill — three short approach steps, stop, scratch at her foot, repeat. Three steps. Stop. Scratch. Repeat. By this point it is no longer physical warm-up. It is the thing athletes do when the body is ready but the mind will not let them stop.

I stand about twenty metres from the runway, my shirt already soaked through. Six hours of flying, one night in transit, and an airless stadium corridor. But this is why I am here. Not to report on someone stepping onto a podium. But to record the stretch of time before that happens, or does not.

Before the start, listen. The stadium is quiet in a very particular way at this hour. Not quiet for lack of people — the stands are nearly half full. Quiet because every sound sits at a low frequency: the plastic sandals of volunteers, the test of the public-address system, the clatter of equipment crates. Nobody is shouting. Not yet.

And at the far end, where the start line of the 10,000 metres was re-chalked slightly later in the day, two Vietnamese women are waiting. One is Nguyen Thi Oanh. The other is Le Thi Tuyet.

Context: one afternoon carrying two finals

ASIAD — the Asian Games — is a multi-sport event run by the Olympic Council of Asia. Athletics is only one of roughly forty sports, but it has a distinguishing feature: it is the sport where the gap between nations is measured in seconds and centimetres rather than goals or sets. There is no luck to shelter behind. No referee to save you. Only the clock and the tape.

This session holds two finals back to back in the same programme: the women's triple jump at 17:44, and the women's 10,000 metres at 19:25. That is the familiar scheduling logic of a multi-sport Games — two events that are physiologically worlds apart placed in the same evening, less than two hours apart. For a coaching staff, it is a coordination problem: if one country has athletes in both, then splitting people, splitting warm-up times, and splitting the medical team's attention becomes a backstage rehearsal that television never shows.

For Vietnamese athletics, this session carries a very specific meaning. In middle- and long-distance endurance events, Vietnam has long been used to the role of continental chaser, while in jumps and throws we are regularly present in the qualifying group but rarely in the top tier. The combination of those two realities produces a particular kind of pressure: the pressure of being underestimated and expected at the same time.

I look, I record, I keep. That is the line I say to myself whenever a session begins. Because in athletics, the most beautiful part usually happens before the gun.

The runway: where technique is betrayed by speed

If you have never stood near a continental-level triple jump runway, you will be surprised by how short it is. For female athletes, the approach is usually 35 to 40 metres, and the entire result is decided in roughly the final four seconds. Four seconds.

The triple jump has three phases: the hop, the step, and the jump into the pit. What almost nobody notices is that the biggest losses do not occur in the third phase — the one most photographed — but in the second. Each ground contact on the change of direction costs roughly 10 to 15 percent of horizontal momentum, and in the step phase, the compressive load along the knee axis can reach several times body weight. Outsiders see spring. Insiders see torque at the knee joint.

Vu Thi Ngoc Ha and Nguyen Thi Huong, in the warm-up area, are doing exactly what every elite long and triple jumper in the world does: running the approach at low speed to lock in the rhythm, then building toward competition speed without executing a full jump. The mechanism is simple and merciless. Every full execution, every accident, is one more withdrawal. You only have a certain number of them inside you.

The current outdoor world record in the women's triple jump is 15.67 metres, set by Yulimar Rojas at the Tokyo Olympics on 1 August 2026. That number should be set beside another condition: to jump 15 metres, a female athlete needs a final approach speed of roughly 9.5 to 10 metres per second. In other words, you cannot triple jump well unless you are already a fast enough sprinter. Technique cannot rescue speed. But speed cannot rescue technique either.

This is where mainstream coverage usually gets it wrong. People praise a beautiful jump and call it a moment of transcendence. But a beautiful jump is the product of hundreds of rhythm-locking sessions at 70 percent speed, where a half-foot misplacement on landing is enough to ruin the whole attempt. At this level, no jump is improvised.

The opposition: the field does not wait for anyone

The force picture in both events is fairly clear.

Japan and China bring athletes of world-class standard in the distance events. That is not diplomatic respect — it is a physiological fact. Endurance training centres in East Asia have built a continuous development system over decades, with a cohort of 18-to-22-year-olds running 5,000 and 10,000 metres at thresholds that many regional nations can only reach through a handful of individuals at the peak of their careers.

Alongside that is a factor rarely stated plainly: the presence of naturalised athletes of African origin, representing Gulf states and several other Asian nations. As a sporting matter, this is entirely legal under World Athletics regulations, and it reflects a reality in which financially resourced nations are buying time — training time that other nations must spend across generations.

For Vietnam, that means the women's 10,000 metres is not merely a race between athletes, but a race between four different training systems. And in such a race, a nation with one elite athlete is always structurally weaker than a nation with ten good ones.

19:25: two Vietnamese women on the start line

Nguyen Thi Oanh walks onto the track in national-team kit. There is nothing loud in her movement. She takes a few light strides down the straight, checks the feel of her legs, and returns to the start. Beside her, Le Thi Tuyet is introduced as the team's young runner — and the way she stands makes that obvious. Shoulders slightly raised, hands lightly clenched, eyes sweeping the stands more often than necessary.

In track and field circles, Nguyen Thi Oanh is still called by a nickname that has always irritated me. Not because it is false. But because it places on a small woman a weight her legs cannot carry for her.

But let us set the nickname aside. Let us talk about the numbers.

10,000 metres on a standard 400-metre track is exactly 25 laps. I say exactly because in this sport, people do not miscount. The athletes do not need to count — officials have electronic boards, bells, and lap counters for each athlete in the lead group. But the board only shows laps remaining. It does not show how many times the body has already crossed the threshold of fatigue.

The mathematics of 25 laps

This is the part I believe television audiences are never told.

A world-class female 10,000-metre runner covers the distance in roughly 29 to 31 minutes. The current world record is 28 minutes 54.14 seconds, set by Beatrice Chebet in 2026. The average speed of that performance sits above 20 kilometres per hour, sustained for almost half an hour. To picture it: that is the pace an ordinary person might hold for about thirty seconds of sprinting.

At that speed, pacing strategy is not an aesthetic question. It is a survival question. Three basic distributions still exist at this distance:

One is the even split. The athlete holds a nearly constant pace across 25 laps, and total time is the accumulation of stability. It is the least mentally taxing approach but exposes the full physical limit, because there is nowhere to hide.

Two is the negative split. The athlete deliberately runs the second half faster than the first. This requires very high muscular glycogen reserve and is the clearest marker of an endurance base built correctly.

Three is the surge. The athlete throws in sudden accelerations to break opponents psychologically before breaking them physically. It is the most dangerous approach, and also the one European coaches most often criticise when applied to the wrong athlete.

When I read an article saying athlete X "has a chance of a breakthrough thanks to reasonable tactics and resilient willpower", I always want to ask: which tactics, at which lap, and measured by what?

The physiology of the final lap

Based on my experience watching hundreds of endurance sessions, there is one popular belief that needs overturning. That belief is: 10,000-metre races are decided in the final lap.

This is visually true and physiologically false.

What decides the outcome of lap 25 is what happened in laps 14 to 20. In that phase, the athlete's body sits in what sports science calls the transition zone: blood lactate is rising but has not yet forced a slowdown, muscular glycogen is depleting at rates that differ between individuals, and the central nervous system begins sending fatigue signals to regulate effort.

In other words, whoever spends less between laps 14 and 20 has more between laps 21 and 25. There is no miracle here. Only accounting.

Three specific variables determine that threshold:

First is running economy. Two athletes with the same maximal oxygen uptake can differ by several percentage points in energy cost at the same speed, simply because of different landing mechanics, stride frequency, and tendon elasticity. Over 10,000 metres, a few percentage points multiplied across 25 laps becomes tens of metres of separation.

Second is lactate threshold. This is the boundary between a pace you can hold for a long time and one you can hold only briefly. An athlete who raises this threshold through dedicated training gains a buffer zone to absorb opponents' accelerations without losing rhythm.

Third is the capacity to resynthesise and reuse lactate as fuel. The body does not discard lactate. It converts it. Whoever does that more efficiently simply hurts less in the final lap — genuinely.

None of this shows up on the scoreboard. But it is the only thing that does.

The blind spot: willpower is not a physiological variable

And here is where I want to speak plainly, as someone who records the sport rather than as a friend of the subject.

The common domestic framing — "waiting for the golden girl to make a miracle", "the chance of a gold medal is extremely difficult, but we still hope" — contains a contradiction inside a single sentence. It acknowledges low probability while encouraging readers to believe in the possibility. The two halves cancel each other out. And what remains after they cancel is an invisible pressure placed on one runner.

The fault here does not lie with the fans. It lies with the frame of reference.

Domestic sports media has a very understandable reflex: when a country has only one continental-class athlete in an event, that athlete becomes a national symbol. Symbols must win. And when a symbol wins, the story told is a story about willpower. When a symbol loses, the story is also about willpower — just slightly short of it.

Both ways of telling it ignore the truth that this sport is decided by accumulated training volume over many years, by the quality of the recovery system, and by how many domestic rivals of comparable standard you can train alongside each week.

If you want to know why a nation does not win gold in distance events, do not look at lap 25. Look at the list of people who ran with you in a Tuesday session three years ago.

I know this sounds cold when said about a woman about to step onto the start line while the stands call her name. But an honest writer is obliged to tell the true story too, even when it lifts no one up.

There is a fire in the changing room. I have seen it many times. It does not burn into medals. It burns into one person coming back to the training ground the next morning.

The counter-angle: a beautiful jump is not a lucky one

On the runway, there is a misunderstanding symmetrical to the one on the track.

On the track, people believe outcomes are decided by willpower. In the jumps, people believe results are decided by a moment.

Both are psychological projections, not technical descriptions. A successful triple jump is the result of a chain of around twenty motor decisions executed in under four seconds: the landing angle, ankle stiffness under load, centre-of-mass position in the transition from hop to step, shoulder rotation to maintain balance, and finally the timing of hip extension in the jump phase.

Get one of those wrong at full approach speed, and the result is not a few centimetres lost. The result is a mislanding, a twisted ankle, and a stolen season.

That is why, in the warm-up zone, Vu Thi Ngoc Ha and Nguyen Thi Huong are not performing full jumps. They are rationing their landings. Those landings have a quota, and that quota does not appear on any scoreboard.

The way we write about these two events must therefore differ. But the way we misunderstand them is identical: outsiders always see the moment, while insiders always see the accumulation.

What is worth watching next

If I stay at the athletics stadium a few more days, I will not stand on the stands. I will stand in the warm-up area.

Because there I learn things the scoreboard never says. Whether someone is warming up slower or faster than usual. Whether they scratch at their foot more or less. Whether they check their shoelaces three times or only once. Whether they glance at the adjacent track when a rival jogs past.

Those are signals that appear in no press release. But they are the truest signals. The heartbeats nobody hears.

And after the gun sounds, after the 25 laps end, after the sand pit is raked flat again for the next attempt, the stadium will go quiet in the way it was quiet at 17:44. The ball has rolled through in my sport, but here there is no ball. Here there are only people and lanes. The people stay, and the lane is long.

One beat, one day, one season. Then the people who stood in the warm-up area today will be back in another warm-up area tomorrow morning, in another city, on another afternoon. Looking back at the road travelled, the one thing I can state with high confidence is this: over 10,000 metres, and on a forty-metre runway, the winner is usually not the person with the strongest will on that particular day, but the person with the fewest accumulated errors in the years before.

What is worth waiting for is not the medal. What is worth waiting for is whether a sporting system has the patience to build enough runners around one athlete. One good runner is an athlete. Ten runners of comparable standard is a sporting system. Only one of those two can produce gold medals consistently.
