Four Walls and 0.08 Seconds: Steenbergen's 56.18 and the Accounting of a Non-Olympic Event

There is a column in my notebook I have labelled "Walls". Since 2026, when I first called an IM race at the outdoor pool in Mirpur, I have written in it after every medley: which turn lost time, which touch bought it back. Last week a new number entered that column: 56.18. Marrit Steenbergen of the Netherlands lowered her own European Record in the 100m Individual Medley at the World Cup — from 56.26 to 56.18. Eight hundredths of a second.

Read the headline from outside the pool and it is a plain "record broken" line. From the deck, it is something else. The 100 IM has four walls: one start and three turns. In a race shorter than a minute and a half, you leave the water four times. Eight hundredths of a second is roughly the arithmetic of one turn.

Steenbergen is not new. Since Paris she has been discussed in the 200 IM and the 100/200 freestyle. But this event belongs to a different world. The 100 IM is not on the Olympic programme and is not contested at the long-course World Championships. It exists only in the 25m pool — the property of the World Cup and the Short-Course World Championships. Every time in this story, from 55.11 to 56.34, is therefore short-course metres (SCM). It cannot be compared with long-course metres.

The distinction is technical, and it is the most important fact here. In a 50m pool, a 100 IM contains one turn. In a 25m pool it contains three turns plus a start — four walls in all. Short-course records therefore tend to look faster than long-course ones: not a swimmer with extra power, but the arithmetic of a shorter pool and more walls. Anyone who places both pools on the same grid has thrown away half the accounting.

One athlete, however, owns this sky. Gretchen Walsh of the United States holds the world record at 55.11, and the seven fastest performances in history are all hers. Steenbergen's 56.18 is the eighth-fastest ever; her previous 56.26 is ninth. She is the second-fastest performer in history while her best time sits behind seven Walsh swims. That gap — between performer and performance — is the real geography of this event.

Short-course 100 IM is not swimming; it is a game played at the walls. Four walls per 100 metres is a density no other event in the sport offers. Fly to back, back to breast, breast to free: each transition is a separate skill. In short course, the underwater after each wall complicates it further. On the Shitalakshya I learned that a race is a conversation between water and will, and over ten kilometres of river there is not a single wall. The 25m pool is the exact inverse — less water, more walls, and everything reduced to wall-time.

That is why Steenbergen's improvement is not spectacular but is meaningful. At this level, 0.08 seconds is almost never the product of a new technique. It is a cleaner turn, a sharper transition, a better touch. The bad news for analysis is that the source report carries no splits, no turn times, no stroke rate. So no one can claim which wall produced the gain; all we can say is that the gain happened somewhere at a wall, not that the stroke model changed.

The 1.07-second gap between 55.11 and 56.18 is enormous over 100 metres. This is a "best of the rest" performance, not a world-record-class one. It needs saying plainly, because a headline carrying the word "record" invites many readers to assume a global frontier has been touched. It has not. Kate Douglass is the third-fastest performer at 56.34, and Steenbergen is 0.16 seconds ahead of her. There is breathing room — but Douglass is an Olympic-class long-course 200 IM swimmer for whom this short-course event is secondary. That 0.16 seconds is event-specific, not a certificate of overall supremacy.

The competition structure matters no less. The World Cup is a third-tier series, well below the Olympics and the long-course World Championships. Three engines drive it: prize money, world-ranking points, and the "Triple Crown" bonus for winning the same event at all three stops. The source report notes that Steenbergen is chasing multiple Triple Crown wins next week. The narrative is being pushed by the series' incentive design, not by championship stature. A post-Olympic short-course series paints a picture of current form and prize incentive, not of peak preparation.

One further detail deserves attention: the same two swimmers finished first and second in both races — Steenbergen and Roos Vanotterdijk of Belgium. That suggests a stable head-to-head rather than a deep competitive field at this stop. As a confidence signal it is valuable; as evidence of peak performance it is not.

Here is my objection. A European Record in the 100 IM is a real achievement — but in an event with no Olympic door. Anyone reading the news as Steenbergen filling a Paris-shaped hole is mistaken. The skills this event builds — turns, underwaters, IM transitions — feed into her Olympic-programme 200 IM and 200 free only partially, and never decisively. Short-course results should be translated into long course with caution.

My second objection concerns my own country. When we applaud records set in 25m pools abroad, we should remember that Bangladesh does not have a single 25m short-course pool in which a national short-course record culture could stand. The outdoor 50m complex at Mirpur is our only serious facility, and it has stood through sun, rain and fog for four decades. From Mosharraf Hossain in 2026 to the Sagor–Himel relay in 2026, that 37-year gap is not a curiosity; it is an administrative indictment. I took the beat nobody wanted, and it taught me where the real game lives.

And our actual tradition — Brojen Das in the Buriganga, six English Channel crossings in open water — has no turns and no walls. The open-water world where we are strong sits at the opposite pole from this turn-dense event. For one month in 2026, Bangladesh watched swimming, and I learned that a full gallery can make a pool holy. But a full gallery does not teach a turn; a pool, a coach and week after week of practice do. Before being dazzled by a record abroad, we owe ourselves the local sum: a pool so children can learn to turn, and a riverbank training programme so they can learn to survive the water. Roughly 40 children drown every day; moving that number down each season is the point at which swimming becomes infrastructure rather than a sport.

Next week the Triple Crown and the 25m pool will carry the story on. If Steenbergen wins it, that is a victory for the series' design, not the announcement of a new era. And the "Walls" column in my notebook will stay empty — until Bangladesh has a pool where our children learn to turn, and a river programme where they learn to live with the water. The day both columns fill at once, I will be more satisfied as a coach than I ever was as a commentator.
