GPS Vests, 11.8 Kilometres and Wasted Runs: Reading the V.League from a Da Nang Training Pitch

Da Nang, 6:15 in the morning. The grass at Hoa Xuan is still wet with dew, and only one man is left in the southern goal. He wears training bib number 22, a GPS pod still strapped across his chest, running his final laps after the rest of the squad has gone inside. On the analyst's screen his numbers glow green: 11.8 kilometres, 34 high-speed sprints, 71 touches in the session. Top of the squad in all three columns.

Three days earlier, in a competitive match, he came on in the 68th minute. Twice he lost his man. One of those two moments led to a goal.

I stood in the technical area watching him gather the last of the training cones, stack them neatly, and only then walk in. Thirty years following teams from training pitch to dressing room taught me that small behaviours like that often say more than a statistics sheet. And those same thirty years taught me something less comfortable: most of what we call "effort" in modern football is being measured with a tape laid in the wrong place.

A season opens with a heartbeat in the press room, before the first whistle. In the V.League that heartbeat now follows a congested calendar: roughly a game every four days in the second half of the campaign, plus the National Cup and long domestic flights. I have followed many seasons like this, and every one of them arrives at the same point about two-thirds of the way through, when the story is no longer about tactics. It is about fitness, about the bench, about who can still stand in the second half of a fourth match in twelve days.

Over the past seven or eight years a new figure has walked into Vietnamese dressing rooms: the GPS vest. V.League clubs now strap tracking devices to players' backs in almost every session. A data analysis department, a concept that barely existed here twenty years ago, has become a permanent fixture at ambitious clubs. Alongside it come match-data platforms where every pass, every duel, every metre run is recorded and rendered into charts for the coaching staff to read on Monday morning.

I have nothing against that. I object to how it is read.

Vietnamese football grew up in a decade whose identity was defined by running. The U23 generation of 2026 in Changzhou taught the whole country that outrunning your opponent can compensate for a great many other things. I was in Russia for that camp ahead of the tournament, and I still remember the late afternoon when Bui Tien Dung, then only 21, sat alone in a corner of the training pitch after a 1-3 friendly defeat to Lokomotiv Moscow. He said nothing to anyone for twenty minutes. He packed his gloves himself, wiped the goal frame clean, and only then went inside. Russia 2026 was so cold that I remembered every breath of the stands for four years afterwards.

But between that emotional story and the 11.8 kilometres on the screen this morning lies a gap I want to make clear.

GPS devices measure three main things: total distance, the number of sprints above a high-speed threshold, and the distribution of running zones by intensity. That is workload data. It answers the question of how much a player ran, and it answers it very well. It does not answer where he ran, to what purpose, and at what moment, which is the question that decides matches.

I call this phenomenon wasted running. A central midfielder dragged out of position by two diagonal passes will cover an extra kilometre and a half compared with the same player in a match his team controls. Same player, same system, two opposite outcomes: in the game where his side is pinned back his numbers look superb, in the game where his side dictates they look modest. The data sheet cannot tell the two apart.

That is why I always read distance covered alongside PPDA, the measure of how many passes a team allows the opponent before making its first defensive action. A low PPDA means high, proactive pressing. A high PPDA combined with high distance means a team being led around by the nose. The same column, two entirely different stories.

Data only has value next to position, and the V.League is buying data faster than it is learning to read it.

Take an example from a recent season. Thep Xanh Nam Dinh won the 2026-2026 V.League with a model that did not require dominating the ball. They defended in a block, accepted ceding territory, then switched quickly through long passes. Nguyen Xuan Son, then still known as Rafaelson, finished the season as the league's top scorer, and the notable part is that his goals did not come from his team outrunning opponents. They came from his team running at the right moment.

Hanoi FC, by contrast, operated in their most successful phases in the opposite direction: keeping the ball, pushing opponents deep, shifting the shape with line-breaking passes. Teams like that usually record a lower total distance than their opponents, especially in the first half, and are dismissed by crowds as slow. In reality they are occupying space, and space is cheaper than energy.

I did not learn this from data. I learned it from training sessions.

At one club I followed for two full seasons, the small-sided game began with twenty minutes of unlimited-opposition duels, then narrowed into a possession drill with touch limits. In the first half everyone ran as if playing a final, and the devices logged beautiful numbers. In the second half the metres dropped sharply, and that was the part the coaching staff watched most closely, because it exposed who understood positioning and who depended on his legs. An assistant there gave me a line I have kept ever since: "The best runner in this drill is usually the one who is lost."

Having followed the V.League for years, I see it repeat on the pitch every round. The midfielders with the highest distance figures in the league usually belong to teams chasing the ball. The midfielders who make me take the most notes often post average numbers, because they are standing in the right place before the ball arrives.

A second metric is being misread here: sprint counts. A sprint only means something when attached to a directed action, a break in behind, a recovery cover, a burst to create space for a teammate. If sprint counts are high while the team's line-breaking passes are low, the likely picture is a side running to no purpose, and fatigue will arrive earlier in the second half of the season.

Gegenpressing is not a sudden gust of wind; it is a wind brewed over seasons of quiet running. That holds for European sides, and it holds for the V.League teams trying to adopt it. I have watched no fewer than ten matches in which a side pressed ferociously for twenty minutes, took the lead, then fell apart in the final thirty because their running load was never distributed. A bench rescues fitness, not structure. If the structure is wrong, the substitute runs to no purpose just like the man he replaced.

Transfers are separations written in advance; only the tears have no draft. In every mid-season window, clubs search for midfielders who run hard and tackle well, and the recruitment file usually stops there. Very few ask the next question: in which system did this player run well, and in mine, where will he be running? That is why so many deals that look sensible on paper become invisible on grass.

I keep a team's rhythm not with a drum, but by never missing a single training session in thirty years. The session is where the story is written; the match is only the print run. The number 22 this morning ran more than anyone. That does not make him the best player. It means he is compensating for something, and the coaching staff should find out what before the season turns another month.

The prevailing reading from outside the pitch treats distance covered as a measure of loyalty. Players who run a lot are praised as committed; those who run little are called irresponsible. In the stands and on forums this is the cheapest and most used yardstick, because it asks nothing of the reader about team structure.

That is where the misunderstanding sits. Good structure reduces the running demand on each individual. When the midfield holds sensible vertical distances and defenders know who covers whom, total team distance falls while chance creation rises. Invert it and a structurally broken team produces individuals with impressive numbers, because they are running on behalf of an entire system that has come apart.

There is another blind spot, and it involves money. Once data becomes the language of assessment, the market pays for players with attractive numbers. A 24-year-old midfielder averaging 12 kilometres a match attracts more attention than a 27-year-old covering 10 but controlling the tempo. This creates an incentive to run, and nobody can criticise a player for running. That is the kind of pressure statistics never record.

I still believe data will be a mandatory part of Vietnamese football over the next decade. But if clubs keep hiring devices before hiring people who can read them, we will produce a generation that runs more and understands position less.

In the rounds ahead, the test lies elsewhere. A team on a winning streak whose PPDA keeps rising is losing its structure, and results will hold only a few more weeks. The ratio between sprints and line-breaking passes at each club will expose who runs with meaning and who runs for show. The minutes given to substitutes in the fourth match of a twelve-day run are the earliest sign of a season about to snap. And the hardest thing to measure, always the hardest: the look in a substitute's eyes at the final whistle. Crowds remember goals; I remember the look in a substitute's eyes at the final whistle.

As for the number 22 at Hoa Xuan, he will wear the GPS pod for many more sessions. What I want to know is not how many extra kilometres he runs tomorrow morning, but whether anyone in the analysis room has the patience to ask why he has to run them at all.

An empty stadium does not stop the ball rolling; it only makes the applause arrive one beat behind the heart. In the V.League this season the applause is more than one beat late, and it is not because the stands are empty.
