The Two-Beat Kick For Triathletes

Efficiency, rhythm, and better pacing in the swim

In this post, I wanted to talk about our leg kick. Specifically, I want to talk about a two-beat leg kick (two kicks to every two arm-stroke cycle).

It’s a really efficient and effective way to swim triathlon swims and long distance swim challenges.

But what is it and why should we try it?

This was prompted by a question from a swimmer who came to our recent two-hour Aquatics Centre swim session in the 50m pool – a fast swimmer, who wanted to swim more efficiently. 

A two-beat kick is the ‘simplest’ freestyle kicking pattern: one kick per arm stroke.

As your right arm is entering the water, your left leg kicks once.

As your left arm enters, your right leg kicks once.

(You can think of it differently. As you right arm starts the pull, the right leg kicks. As the left arm starts the pull, the left leg kicks).

So instead of lots of continuous kicking, you’re just doing two well-timed kicks per full stroke cycle (one per side).

The purpose isn’t to generate propulsion – it’s to support rotation, maintain balance, and keep the stroke connected and efficient.

Because, if I’m honest, most triathletes aren’t very good at kicking.

The kick is often too big, from the knees, poorly timed – and ends up creating more drag than propulsion.

So, in my experience, more kicking doesn’t mean more speed. In many cases, it’s the opposite: more effort, higher heart rate, and little (or no) improvement in pace.

That’s where the two-beat kick comes in.

Instead of trying to generate speed from the legs, it focuses on efficiency, timing, and connection. If done well, it becomes your most efficient “default gear.” Over long distances, it allows you to swim well without constantly spending energy through the legs.

• Efficiency over over-kicking. Strip things back to what you actually need – no wasted movement, no unnecessary effort.

• Better body position. A small, well-timed kick keeps you balanced and aligned, reducing drag without burning energy.

• Rhythm and connection. It links the upper and lower body so the stroke feels like one coordinated movement, not two separate systems.

• Deliberate timing. The legs aren’t just doing something in the background, or something random, they’re synced to the stroke, reinforcing good technique.

• Lower heart rate. Big, constant kicking drives effort up quickly. A two-beat kick keeps things calmer, helping breathing stay controlled.

• More sustainable swimming. You avoid that early spike in effort that can leave you hanging on later in the swim.

• Better pacing control. With effort under control, you can settle into a steady, manageable intensity – and hold it.

All sounds great doesn’t it? But how do we do it? 

A good way to start building a two-beat kick is to focus on just one side. Use your breathing as the anchor. As you finish the breath and rotate back into the water, add a single, well-timed kick. Don’t worry about what the legs are doing the rest of the time – let them be loose. The goal is simply to connect that one kick to the rotation. Once that starts to feel natural, you can begin to mirror it on the other side and build it into a full rhythm.

So, what do you think? Are you going to try it?
