For about four months last year, Rafa's 100 Free sat at the exact same time. Not a hundredth faster. I was checking her results after every single meet, refreshing pages, comparing splits — getting frustrated for her, honestly more frustrated than she was. Michelle finally told me, "You need to stop looking at the numbers every week. You're going to drive yourself crazy before she does."
She was right. And if you are the parent who quietly checks times on the drive home, this is the article I wish I had read during those months.
Your child has been swimming competitively for a few years now. Early on, the personal bests came almost every meet. Two seconds dropped here, a full second there, sometimes even bigger jumps. It was exciting, addictive even. And then, almost without warning, the times stopped falling.
Weeks pass. Then months. The clock barely moves. Your swimmer is training harder than ever, but the results just are not showing up. You are worried. They are frustrated. And a quiet question starts circling: is something wrong?
The answer, almost always, is no.
Why Plateaus Happen
Swimming improvement follows a predictable curve, and the data confirms it. A large-scale study published in PMC, analyzing 9,956 swimming years of backstroke performance data from 2006 to 2017, found that young swimmers improve by 9-10% per year between ages 8 and 10, around 5% per year between ages 11 and 14, and just 1-2% per year from ages 15 to 18. Between the ages of roughly 8 and 13, kids experience rapid gains. Their bodies are growing, their technique is sharpening, and everything comes together quickly. During this phase, dropping multiple seconds per meet is common, and it feels like progress will never slow down.
But it does. Once a swimmer reaches a certain level of physical and technical maturity, improvements shrink dramatically. Instead of two or three seconds per season, the gains become fractions: one percent here, half a percent there. For older age-group swimmers and high schoolers, improving by one to two percent per year is actually excellent progress, even if it does not feel like it.
According to the same PMC study, female swimmers tend to hit this plateau earlier, often around age 14, as hormonal changes during puberty shift body composition. Male swimmers typically plateau a little later, around age 16, though the timeline varies widely. In both cases, the slowdown is a natural part of athletic development, not a sign that your child has peaked.
Plateaus Can Last Longer Than You Expect
Some plateaus last weeks. Others last months. A few last more than a year. It can be painful to watch, especially when your swimmer is putting in maximum effort and seeing no reward on the scoreboard. But consider this: during a plateau, the body is often making adaptations that are invisible, building aerobic capacity, refining neuromuscular pathways, and developing the strength that will eventually unlock the next breakthrough.
The plateau is not wasted time. It is preparation.
It Is Not a Sign of Failure
This is one of the most important things a parent can internalize. A plateau does not mean your child is not talented. It does not mean the coaching is wrong. It does not mean they should switch clubs, add more hours, or try a different sport. It means they are at the stage where improvement requires patience, consistency, and trust in the process.
Every Olympic champion hit plateaus. Many of the best swimmers in history went through long stretches with little or no improvement before breaking through to the next level. USA Swimming's 2024 demographics report shows that membership retention sits at 66.9% — the lowest since 2019 — with the worst dropout rates among 13-year-old girls and 17-year-old boys. Many of those dropouts happen during a plateau. The difference between those who stay and those who leave was not talent. It was persistence.
What Parents Can Do
Your role during a plateau is not to fix it. It is to help your swimmer get through it with their love of the sport intact.
Shift the focus from times to technique and effort. Ask your child what they worked on in practice, not what their times were. Celebrate the mornings they showed up when they did not feel like it. Recognize the effort it takes to keep going when results are invisible.
Celebrate non-time achievements. Did they lead a warmup? Help a younger teammate? Nail a new turn? Get a compliment from the coach? These milestones matter, and noticing them tells your swimmer that their value is not defined by a number on a scoreboard.
Talk to the coach. Coaches understand plateaus. They see them constantly. A good conversation with the coach can reassure you and may lead to small training adjustments, a new focus on technique, or a change in race strategy that eventually breaks through the stall.
Avoid comparisons. Every swimmer develops on their own timeline. The teammate who is dropping time right now may hit their own plateau next season. Comparing your child's trajectory to someone else's is almost never productive and often harmful.
Be honest about your own frustration. If the plateau is bothering you more than it is bothering your swimmer, that is worth examining. Sometimes the best thing a parent can do is step back and let the athlete own their journey.
The Breakthrough Will Come
Plateaus end. Sometimes they end gradually, with small drops spread over many meets. Sometimes they end explosively, with a massive best time that seems to come out of nowhere. Either way, the work put in during the flat period is what made it possible.
Your swimmer does not need you to fix the plateau. They need you to believe in them while they are in it. That belief, steady and patient, is the most powerful thing you can offer.
