Why Your Swimming Pace Feels Wrong: The Psychology of Effort in Water

Why Your Swimming Pace Feels Wrong: The Psychology of Effort in Water

Published on 1 September 2026

When you swap running or cycling for swimming, your body’s built-in speed test stops working properly. You might feel like you are gliding fast, only to look at the clock and see a slow time. Other times, a swim that feels terrible turns out to be your fastest lap of the week.

This happens because your brain learned to measure hard work while living on land. On ground, exercise gives you clear signals. Every step sends a small shock through your feet and legs. You feel gravity pulling you down, and you see the ground moving quickly beneath you. Your brain uses these strong signals to tell you how fast you are going and how hard you are working.

In the water, those familiar signals disappear.

First: water floats your weight. Floating takes away the heavy stomping feeling in your joints. Without those hard bumps, your brain thinks the work is easier than it really is.

Second: water is heavy and thick. Pushing through water is much harder than pushing through air. To swim twice as fast, you have to push eight times harder. If you try twenty percent harder, you might only move a tiny bit faster. Most of your extra energy just gets lost pushing against the water. This makes you feel stuck or slow, even when your muscles are working as hard as possible.

Third: swimming covers your ears and hides your view. Looking at a line on the bottom of the pool does not help you judge speed. Floating through calm water does not feel the same as feeling the wind rush past your face when you run.

Because your brain gets these confusing signals, you cannot trust your feelings to guess your swimming speed. Instead of guessing by feel, rely on simple tools like the pool clock, counting your strokes, or following a set training plan to stay on pace.

Overcoming these tricky water signals is much easier with tailored guidance. At SwimExpert, our experienced instructors work with you individually in dedicated private lessons to break down your stroke mechanics and teach you how to read your pacing accurately. Whether you want to build stamina, improve your technique, or hit specific fitness milestones, our tailored one-to-one swimming instruction gives you the exact tools and feedback needed to reach your personal goals.

Absolutely amazing team have helped our daughter so much with her swimming but also her water confidence is amazing you wouldn’t think it’s the same child who would not even enter the water

Very helpful support staff and very kind of experience with them

Excellent staff with great atmosphere and our kids love it

Arlene teaches my 6 year old and he is so kind and thoughtful. My child has made so much progress and always wants to come to swimming lessons

Friendly staff and environment. Children learn by playing and get confident as reassurance and guidance is constant. Strongly recommend!!!

We had Oscar today as our usual teacher wasn’t here and he was amazing! So good with the kids and really helped push our daughter’s skills further than she has been in a super positive way. Thanks so much Oscar!

Hi, This is Anjali, here... I am delighted to say that Fern, my swim instructor was the most sweet, kind, gentle, patient and truly an amazing coach... I am so lucky to have found her, I commend her work and recommend swim expert to anyone who is a complete beginner, want to learn, or even brush up, I was someone who was especially reluctant but Fern made me feel so comfortable, I cannot put it into words, how much she helped me, I will recommend swim expert and Fern as coach, worth every penny!

We could not be happier with Chester as a swimming teacher for our 5 yr old daughter. She had really helped grow her confidence in the water.

Matthew has been absolutely amazing in helping our 7 year old with his confidence. His swimming has come on incredibly, he's swimming independently and loving it. Swimming is now something he enjoys and wants to do. I couldn't recommend Matthew at SwimExpert enough!

Couldn’t be happier with Chester’s teaching. Both our children have improved so much in such a short time and they really enjoy their lessons. Chester has a great rapport with them. She’s makes it fun, while also being really clear and not giving up until they get the technique just right. Would definitely recommend.
