Anastasia Gorbenko's 52.11: A Beautiful Underwater Song That Only Plays True in a 25-Yard Pool

My old stopwatch clicked to 52.11. On the CSL Match 1 livestream, Anastasia Gorbenko had just touched the wall after four lengths in a 25-yard pool. I pressed again. Still 52.11. A third time. Same number. Then the phrase “third-fastest performance all-time” swept across swimming forums faster than she could clear the water.

I sat still for ten seconds. What stopped me was not the time. It was the label attached to it.

Eleven years of holding a microphone and a stopwatch taught me one reflex: whenever someone brands a swim “all-time,” the first question is how long the pool was.

Three pool systems, three different worlds

The College Swimming League races in short-course yards, or SCY. The pool is 25 yards, roughly 22.86 metres. This is the traditional standard of American collegiate swimming.

The other two systems are short-course metres (SCM, a 25-metre pool) and long-course metres (LCM, a 50-metre pool — the Olympic and World Championship format). Only SCM and LCM are ratified by World Aquatics for record purposes. SCY sits outside that system, and this is not a trivial administrative footnote.

The technical consequence is bigger than it looks. A 100-yard race covers just 91.44 metres — nearly nine metres shorter than the 100-metre equivalent, with more turns packed in. SCY times are therefore systematically faster than SCM and LCM marks. Placing 52.11 next to a long-course number and declaring a winner is wrong from the first premise.

Gorbenko is not an overnight phenomenon. She is an Israeli swimmer training inside the American collegiate system, and she already owns a bronze medal in the 100 IM from the 2026 short-course-metres European Championships. The technical foundation was already there. Her training model is a classic hybrid: the Israeli national system supplies international racing craft, while the US collegiate environment supplies volume and depth of competition.

What deserves attention is the speed of conversion from a 25-metre pool to a 25-yard pool.

The gap between 25 metres and 25 yards is wider than it looks

Any swimmer who has raced both short-course metres and short-course yards knows the strange sensation of touching the wall earlier than expected. A 25-yard pool is nearly 2.2 metres shorter per length. Across a 100, that is four lengths and almost nine metres of difference.

I once stood at the wall counting the breathing rhythm of young swimmers as they moved from a metre pool to a yard pool during a friendly session. The first sensation is always the same: breathlessness, because the rhythm is compressed and the arms turn over sooner than the body clock allows.

In the 100 individual medley, the short-course race runs butterfly, backstroke, breaststroke, freestyle — one length per stroke. That means each stroke lasts only 22.86 metres. Over such a short distance, raw swimming speed is not decided by speed alone but by three other things: the start, the underwater phase after each turn, and the quality of the turn itself.

More precisely, the decisive segment of a short-course 100 IM is usually the breaststroke length and the breast-to-freestyle transition. That is where rhythm breaks hardest, where time bleeds most, and where swimmers with strong turning mechanics separate from the field. Three turns in a 100-yard race are three chances to gain and three chances to lose.

Pressing data does not lie, but it whispers the name of a star still half asleep. Here, the data most needed is the split sheet. And the split sheet is missing from the source report.

No start reaction time. No per-length splits. No stroke rate or distance per stroke. Which means any claim that “she swam it technically perfectly” is speculation. I will not write that.

What I can verify lies elsewhere.

First, adaptation speed. The report states this was her first time swimming the event. But she already owns a short-course-metres 100 IM background with a European medal. Those two facts fit together in only one way: “first time” here means first time in short-course yards, not first time in the 100 IM as a career event. Read it the second way and the information contradicts itself.

That distinction matters because it changes the meaning of the result entirely. A swimmer racing a 100 IM for the first time ever and landing a top-three all-time mark is a miracle story. A swimmer who has won a European medal in a 25-metre pool, converts to a 25-yard pool, and immediately reaches that level is a technical story: turning and underwater skill transferred almost intact.

I lean toward the second story, and it is far more interesting. It says something about modern swimming: in short course, what travels between measurement systems is not raw speed but wall craft.

Second, the cluster effect. On the same night, Bella Sims swam 52.69 for sixth all-time. Caroline Larsen swam 53.05 for tenth. Three top-ten marks in a single session.

Based on my experience tracking meets, a cluster of elite performances in one night usually comes from one of two sources: a fast pool combined with a rested state, or a historical list so thin it gets rewritten constantly. In the case of the short-course-yards 100 IM, both are true, and they amplify each other.

A night with three top-ten swims is not just one swimmer’s night. It is a signal about the event’s overall level.

The “third all-time” label stands on sand

The 100 IM is not an officially scored event at the NCAA Championships. As a result, the all-time list for this distance is assembled manually across meets rather than managed as a standardised federation table.

Add the fact that SCY carries no World Aquatics ratification, and “third all-time” becomes a community title, not an official record. It has media value. It has no regulatory value.

Three concrete consequences follow.

One, the two performances faster than 52.11 are never named in the source. Readers have no way to measure the gap to the top. A ranking without a named leader cannot be used for positioning — only for impression.

Two, there is no split data. Pacing, turn efficiency, and the breast-to-free transition cannot be assessed. Half of any technical analysis is therefore locked.

Three, the historical sample for this event is too thin for the label to hold firm. One meet can shift the order by several places. A number that unstable is not a landmark.

So what actually deserves attention here?

Not the time. It is the arrival of a league built on head-to-head team scoring, where internationally credentialed swimmers agree to race mid-season in the collegiate calendar. The report references a “jackpot one point” mechanic — a scoring rule in which a swimmer who beats an opponent by a set margin steals that opponent’s points. That mechanic is tied to the International Swimming League, which has ceased operations.

An ISL-style team league reviving inside American collegiate swimming is a bigger industry signal than any single time. It shows organisers trying to repackage swimming as entertainment, where every swim carries points, direct duels, and team drama.

As someone who has swum and written across multiple sports, I see this as the part worth watching long term. A league can produce one fast number in one night. A league model can change how an entire generation of young swimmers schedules its season.

Every sport is its own universe, and I am lucky to travel as a wanderer between those orbits.

The real test sits in a 50-metre pool

Gorbenko’s real test is not in the yard pool. It comes the next time she steps onto a 50-metre start block. If her turning and underwater foundation transfers to long course, we will know whether 52.11 reflects global class or simply the gift of a shorter pool.

For the CSL, the existential question is whether the model survives several seasons. The ISL once had stars, television and money — then it folded. A league’s quality is not decided at Match 1.

I run like an athlete and jump between sports like an adrenaline addict. And I will keep pressing the stopwatch at every wall touch, even when the label arrives before the result.
