12 Kilometres and Still Losing: The "Ineffective Running" Trap Blurring Vietnamese Football

Minute 87 at Thong Nhat Stadium, the away side's midfielder crumpled after his thirty-first sprint of the match. The stat board on the big screen lit up its final line: 12.4 kilometres covered, the highest of the game. His team left the pitch beaten 0-2. The stands still applauded, because an old default in the minds of Vietnamese fans remains intact: running a lot means you gave everything, means you deserve sympathy.

I sat in stand B, opened three data tabs on my phone, and saw the opposite. That 12.4-kilometre figure is a passport for a system that was already broken before the ball rolled. Distance covered does not measure value. It measures fatigue.

Over the past three seasons, GPS vests have become Vietnamese football's new toy. V.League clubs have started publishing post-match numbers: distance, sprint count, top speed. Local media repost them, social media shares them, and a new frame of reference is born — a player who runs 11 km is a warrior, a player who runs 9 km is called "lazy".

That consensus sounds reasonable. Sport is effort, effort is measured in sweat, sweat is measured in kilometres. Everyone understands it that way, from fans to coaching staffs, from commentators to sponsors.

I once believed it too. In 2026, when I sat taking notes at a training session and was sneered at by male colleagues for "what does a woman know about tactics", what I looked at was not kilometres. I looked at a young midfielder named Pham Gia Hung who ran only 8.7 km but delivered four passes into the channel. Three months later, he was called up to Vietnam's U23 side. There are talents buried under contemptuous glances, and I watched them bloom.

The problem is that distance covered is a crude metric, easy to dress up, and almost incapable of distinguishing effective running from ineffective running.

Break it apart. A player who runs 12 km can be split into four groups: running to create space, running to press, running to chase a lost ball, and running... for the sake of running. The fourth group is the largest at clubs without structure. When the midfield loses its line, each player swims alone in his own void, and distance spikes as a survival reflex rather than a tactical choice.

Put another way, we must split "distance" into "useful distance". High-intensity running is what deserves attention. A player who runs 12 km but covers 10 km of that at walking and jogging pace has effectively completed only 2 km of value. Meanwhile a teammate who runs 9 km with 3.5 km at high intensity contributes more to the team's structure.

Look at PPDA — passes allowed per defensive action. A good pressing side has a low PPDA, meaning it wins the ball high, near the opponent's goal. A team that runs a lot but has a high PPDA is a team running in circles. Its distance is heavy breathing, not a blade.

I once dug through a Premier League dataset from 2026 to 2026 and found something that made me sit back down: away teams scored 43% of their goals in the final 15 minutes. That number is not about fitness. It is about home sides running more in the first half, burning energy on meaningless duels, then collapsing at the end — when focus matters more than kilometres.

Recall the 2026 World Cup final in Russia: France beat Croatia 4-2 while controlling only 39% of possession. The whole world praised Deschamps, while I wrote that football was the real loser. France won the trophy, but football was the loser — that story never gets old. When a team accepts conceding the ball and runs after the opponent, its distance rises, but that is a sign of tactical deference, not strength.

Elite football has moved past the era of worshipping distance. Analysts have shifted to xG (expected goals) to measure chance quality, to progressive passes to measure ball progression, to pressure metrics to measure the value of every metre run. Distance is now a secondary metric, used to assess workload, not to judge class.

In the V.League, we stand at the very beginning of that road. And I worry I will witness a generation of players learning to run for a pretty number, instead of learning to run into the right place.

Take the concrete example from the match I mentioned. That 12.4-km midfielder had 47 touches, but only 6 passes forward toward the opponent's goal and no successful dribble. By contrast, the 9.1-km player on the winning side had 31 touches, 4 key passes and one duel won in midfield that led to the second goal. If you only read the distance board, you will praise the loser and overlook the winner.

I re-checked these numbers against three independent sources before writing, because I know an empty hot take with no data will destroy the very thing I have built over nineteen years.

This is where data must be read in clusters, not in isolation. A single detached metric is a polite lie. A cluster of metrics is an uncomfortable truth. A sports journalist has a duty to choose the uncomfortable truth.

What I want to see next season is not a distance leaderboard. I want to see clubs publish pressing metrics, progressive passes and the share of duels won in the opponent's half. Then fans will have enough data to judge for themselves, instead of trusting a single number selected to show off.

Where could I be wrong? In that distance covered is not entirely useless, and I do not want to sell it cheap.

For teams that press high, running volume is a matter of life and death. A midfield line playing gegenpressing that runs under 10 km per man will almost certainly break. At those clubs, high distance correlates with chances created, and dismissing it is the opposite mistake. The line between "ineffective running" and "purposeful running" lies not in the number, but in the structure standing behind that number.

The second blind spot is that I am viewing Vietnamese football through a European lens. The V.League has different tempo, pitch quality and fixture density. A player running 12 km on a poor surface, under 34-degree heat, is doing harder work than his counterpart in the Premier League. Applying Man City's PPDA to a mid-table V.League side is a lame comparison.

I still hold what I believe: figures must be verified from at least three sources before they become a claim. But I admit I may have been too harsh on numbers that are trying to tell a real story.

People call me a contrarian; I call myself a finder. And what I found this time is not a lazy player, but a football culture learning to love easy numbers.

In the silence of empty stands, data whispered things no one expected. Data gives me numbers, but empty stands give me questions. The question is this: when clubs publish distance covered again next season, will we praise the one who ran the most, or the one who ran right?
