Short Course and Long Course: The Gap Vietnamese Swimming Must Re-Measure After Rio 2026

In August 2026 I was seventeen, sitting on the edge of the Nha Trang city pool after an afternoon session, my phone propped sideways on the tiles to watch the women's 100m breaststroke final at the Rio Olympics. Lilly King touched first, Yulia Efimova behind her amid jeers from the stands. I clicked my stopwatch out of reflex, then realised something so silly I had to laugh: the event I loved most, the 50m breaststroke, does not exist at the Olympic Games.

That is true of every Olympics, not just Rio. The Olympic programme has exactly one 50m event, and it is the 50m freestyle. Breaststroke, backstroke and butterfly all begin at 100m. Which means a swimmer can be the fastest human on the planet over 50m breaststroke, break the continental record several times, and still never get a lane at the biggest meet of all. That gap followed me all summer, and it became the first question I carried into the job: which ruler are we using to measure sport?

2026 gave Vietnamese sport more to talk about than any year before it. On 6 August, Hoàng Xuân Vinh shot 202.5 points in the men's 10m air pistol final, beating Brazil's Felipe Almeida Wu by exactly 0.4 points to win the first Olympic gold medal in Vietnamese sporting history. Four days later he added silver in the 50m pistol. The whole country turned its eyes to Rio, and for the first time Vietnamese people were allowed to believe they could stand on the top step of an Olympic podium.

In the pool, Nguyễn Thị Ánh Viên entered the Games at 19, her second Olympics. She swam several events at once: individual medley, butterfly, backstroke. The season closed without a medal. But there was a technical question Vietnamese media barely asked that year: which pool is Ánh Viên strongest in, and does that pool have an Olympic lane?

In December 2026 the World Short Course Championships closed the season in Windsor, Canada. It is where records fall constantly, and also where one particular misunderstanding breeds most easily: taking a short-course mark, placing it beside a long-course mark, and calling the result a breakthrough.

A 25m pool and a 50m pool are two different events wearing one name.

In a long-course pool the 50m breaststroke is a single length. There is no turn. The swimmer leaves the block, performs the underwater pullout, and swims straight to the far wall. In a short-course pool the same distance includes one extra turn and one extra underwater phase. In breaststroke the pullout consists of one dolphin kick, one arm pull and one leg kick, all of which must stay inside the rulebook. A second dolphin kick means disqualification.

At world level each turn plus pullout is worth several tenths of a second. In a 30-second race, several tenths of a second is a whole sky. So when a swimmer goes 29.5 in short course and 30.0 in long course, that distance belongs to geometry, to the number of turns she is given.

The women's long-course 50m breaststroke world record has stood at 29.48 seconds since 2026, set by Rūta Meilutytė at the World Championships in Barcelona. For years afterwards it did not move, while the short-course record over the same distance fell far more often. The reason is not that later athletes are better than earlier ones. The reason is that a 25m pool gives them one more turn to exploit the push off the wall.

The consequence is that World Aquatics ratifies and stores short-course and long-course records as two separate sets. Anyone working with data assumes that as standard. General readers do not, because nobody writes 25m pool or 50m pool into a headline.

Next comes the performance-curve trap, which I consider the most common professional error in Vietnamese sports journalism.

The precision of a 50m swim is about one hundredth of a second. If a swimmer takes half a second off her own time within a year, that is a large jump, worth recording and also worth checking. The first thing a writer must do is not build a headline, but reopen every mark and ask: how many metres long was the pool for this swim?

If you cannot answer that, you are stitching two different datasets into one straight line and calling it progress. I have clicked my stopwatch through a great many swims, and the lesson repeats itself exactly: data do not lie, but the person presenting the data can.

The most underrated part of a 50m race sits in the very first second.

The reaction time off the block for an elite swimmer falls between roughly 0.6 and 0.7 seconds. In a 30-second race, a 0.1-second difference at the start equals one third of the gap between two final slots. After years of rewatching footage, I notice that fans remember the final time but rarely remember the reaction. Coaches remember, which is why short-course training plans often devote an entire session to counting dolphin-kick rhythm after a turn.

Then comes the error of reading a continental record as global dominance.

A continental record is a real milestone, but it speaks about one continent only. Modern Asian women's breaststroke still absorbs pressure from European and American swimmers at world meets. Placing a continental record beside a world record without stating the distance between them makes readers think the global crown has changed hands.

The most interesting thing about the 50m breaststroke, 50m backstroke and 50m butterfly sits outside the pool: they have no Olympic lane.

This is a structural feature, not a complaint. An entire career can reach world class over 50m and never touch the biggest medal. For Vietnamese swimming it becomes a very concrete investment problem: the 50m is the shortest road to a continental medal and, at the same time, a dead end for Olympic ambition. Those two goals need two different kinds of preparation, two different training cycles and two different ways of reading a time.

In the women's breaststroke, the Asian map has two clear poles: China and Japan.

China has depth in the sprint group, with several swimmers competing for places. Japan has a durable layer of veteran swimmers: Satomi Suzuki won an Olympic medal in breaststroke and stayed near the top of the continent for years afterwards. Vietnam sits behind both in the breaststroke lanes, and that gap cannot be closed with slogans.

From that angle the strategic choice is not about trying harder but about picking the right distance: the 100m breaststroke has an Olympic lane, the 50m breaststroke does not. A country with few investment slots should know which door it is buying a ticket for.

With Ánh Viên, the better question than did she win a medal is which pool her best time belongs to. Tracking every one of her swims in 2026, I noted each mark and reminded myself not to merge them into a single curve. Hearing the stands roar, I know I am writing with sweat, not only with ink. But the writer's sweat cannot substitute for checking the numbers, and that is the part I have to do myself.

The contrarian view: a short-course record is no smaller than a long-course record. It is the record of a different event.

The error lies in the comparison, not in the plaque. When someone calls a short-course mark not quite the real thing, they are using the standards of one event to grade another. A swimmer who takes a continental record in a 25m pool has fully mastered turns, pullouts and breathing rhythm inside a window shorter than a television advert.

At the same time, the fact that 50m events have no Olympic lane does not make them meaningless. It makes them functionally different. The 50m is the laboratory of pure speed: the start, the reaction off the block, the pullout, the stroke rate. All of it also decides the 100m. Dropping the 50m because it carries no Olympic medal means dropping the very speed gauge of the 100m.

I run like an athlete, I jump between sports like an adrenaline addict. And the more I jump, the more I see one thing: no event is a minor event. There are only events that people have filed in the wrong drawer.

What I want to do next year

In 2026 I want to build a small table for Vietnamese swimming: one line per national record, stating the distance, the pool length, the date it was set and one final column, does this event have an Olympic lane. No software, no money, just a pen willing to cross-check a few sources before writing.

Every sport is its own universe, and I am lucky to be a traveller among those orbits. But a traveller has to remember which planet she is standing on, 25m or 50m, before telling anyone about the journey.
