Copenhagen 2026: Three Champions, Three Ways of Running, and a Lesson Still Fresh for Vietnamese Badminton

In the final week of May 2026, in Copenhagen, three players climbed to the top of the world podium in three completely different ways. Sun Jun won by barely making mistakes. Kim Dong-moon won by showing up in two finals. Camilla Martin won by attacking under the weight of a whole nation waiting for her in the stands.

I once read a results sheet wired in from Europe and missed a line. At the time I only wrote down “Kim Dong-moon, men's doubles champion”, then turned to the person next to me and said Korean badminton had produced another doubles specialist. Only later did I read the whole page: same tournament, same player, he had also won the mixed doubles. The half I left behind was the half that mattered.

A good presenter is not the one who says the right thing, but the one who knows when to stay silent between two games — and who knows what he has just left out. Since then I have made a habit of reading sports results to the very last line.

A sport changing how it kept score

In 2026, badminton had been an Olympic sport for seven years, since Barcelona 2026. The centre of power had shifted to Asia, with Denmark as Europe's outpost. But the thing changing faster than the map of power was the scoring.

Throughout the 1990s, badminton used the old service system: only the serving side could score, men played to 15 points per game, women's singles to 11, and two games won the match. A match could last more than an hour. Every rally therefore carried two meanings at once: winning the point, and keeping the serve. Miss while holding serve and you lost both the point and the initiative.

The 2026 season compressed several major events into a few months. In March, the All England closed with Peter Gade taking the men's singles title. In May, the Sudirman Cup was held in Copenhagen and went to China. Immediately afterwards the individual World Championships opened on Danish soil.

In Southeast Asia the picture was more familiar: Indonesia and Malaysia shared most of the glory, and the 19th SEA Games in Brunei in August 2026 was still their stage. Vietnamese badminton stood outside the medal contenders then, caught between a thin coaching base and a domestic tournament system not yet dense enough to sustain players over the long run.

That distance is what makes the Copenhagen 2026 story worth revisiting. Not to praise the winners, but to understand why the same rules produced three such different kinds of champion.

Sun Jun and the value of not missing

Sun Jun won the men's singles. His game was a direct answer to the arithmetic of the old rules: the side holding serve only had to avoid mistakes to keep control. He cleared high, squeezed the net, and waited for opponents to grow impatient. Every extra rally was one more chance for the other man to miss.

From the outside people called it defence. Look closer and it was arithmetic. When points come only from the serving side, scoring means accepting risk. Sun Jun turned patience into a form of pressure and pushed all the risk onto the man across the net.

The price was paid in the legs. That model demanded near-limitless endurance and footwork that saved every centimetre. In badminton every rally starts with a footstep — athletics taught me to see that. A great defensive player is really a middle-distance runner who happens to hold a racket.

Kim Dong-moon and the lesson from the doubles lane

Kim Dong-moon won two events: men's doubles with Ha Tae-kwon, and mixed doubles with Ra Kyung-min. This is the detail that many 2026 reports noted in a hurry and then dropped, mine included.

The Korean doubles school of the time was built on one very simple principle: do not lift the shuttle. A lifted shuttle gives the opponent time to set up an attack; a flat, driven shuttle takes that time away. Serve short so as not to open up the opponent's strength. Intercept at the net so the rally ends before it becomes an attack.

The understanding between two partners in a pair is like a relay: one fumbled baton and the whole leg collapses. Kim Dong-moon and Ha Tae-kwon did not need the prettiest rallies of the tournament. They only needed not to fumble.

Playing two events at a World Championship is a brutal physical problem. The flat game suits that problem in a very practical way: shorter rallies, shorter games, legs saved for the next match. Versatility and a fast style do not oppose each other. They feed each other.

In the mixed doubles, Ra Kyung-min held the net while Kim Dong-moon covered the back court. That is the classic division of labour in mixed doubles, and the reason it demands two heads that understand each other before it demands two strong arms.

From my own experience watching matches of this period, men's doubles had a noticeably lower average number of shots per point than men's singles: all four players stood close to the net, and nobody wanted to lift.

Camilla Martin and the problem of the stands

Camilla Martin won the women's singles at home, at a time when the women's game was in Chinese hands. It was one of the rare occasions Denmark had a world champion in the women's singles.

Women's singles was played to 11 points then, shorter than the men's game, so the reward for attacking early was much greater. Martin pressed from the first serve, moved to the net, and gave her opponent no room to breathe. She turned the home crowd into a competitive resource.

At the same tournament Ge Fei and Gu Jun still delivered the women's doubles title for China. Chinese badminton's strength lay in its system, not in any single individual.

What the medal table does not say

After every major tournament the same line is repeated: the sport is getting faster. I read the Copenhagen 2026 results the other way. This was a tournament of control. The winners were not the hardest hitters but the players who controlled how often they were forced to take risks.

Sun Jun won by pushing risk to its lowest level. Kim Dong-moon won by taking time away from his opponents. Camilla Martin won by pushing risk onto the other side first. All three played the risk arithmetic; they differed only in which direction they pushed it.

The image of Kim Dong-moon winning twice at a single World Championship is usually told as the story of a superman. I think it is the trace of a transitional moment. Place that image in today's badminton, where a top player rarely dares enter two events at a major because of the schedule and the physical load, and it becomes clearer: 2026 still rewarded versatility, but had already begun to demand specialisation.

That threshold is the real story, and it is not on the medal table. The medal table only records the names of the winners. It does not record that the true value of the tournament lay in the pairs, in the coaching, in the things that must be built before anyone walks out for a final.

A lesson from the running lane

Vietnam in 2026 looked at Copenhagen from a great distance. Geography, though, was not the hardest part. The hardest part was a question about how to build a base: teach a player several events before someone asks them to choose one.

A sports system that splits children away from multi-event training too early saves time in the first few years, then pays for it with a whole generation short of compensating skills. Diversity at the foundation stage, on the other hand, produces players who can improvise when their familiar game is read.

Copenhagen 2026 leaves a task more concrete than finding a champion: build a base wide enough that young players are allowed to try several positions before professional competition forces them to choose. Big sporting events do not need loud voices; they need storytellers in rhythm with the hearts in the stands. And sometimes the most useful lesson sits in the last line of a results sheet we never finished reading.
