10 Steps to Championship-Winning Relay Starts
What if I told you the fastest swimmer in your relay…isn’t the one in the water? It’s the one on the block.
Relay starts can WIN or LOSE races—and most swimmers don’t train them enough. A great relay start isn’t just a dive. It’s timing, momentum, and trust between teammates. When all three line up, you’re gaining free speed before you even take your first stroke.
Why Relay Starts Matter More Than You Think
Here’s the deal…
A relay start is often 0.2–0.4 seconds faster than a flat start. That might not sound like much, but at a championship meet, that’s the difference between touching first or missing the podium entirely.
The problem? Most swimmers rely on instinct instead of training. They guess their timing, they rush the dive, or they forget that the entire movement starts BEFORE they even leave the block.
Understanding the Main Types of Swim Relay Starts
Before we break down technique, you need to understand your options.
The step forward relay start is the most commonly used. It’s controlled, repeatable, and gives swimmers a strong balance between power and timing. You start with one foot forward and the other on the wedge, then step the wedge foot forward into the takeoff.
The step over relay start is more aggressive. Swimmers generate more forward momentum by stepping through the movement instead of just into it. This can be done with one foot or both feet moving forward, depending on the athlete’s style and confidence.
Then there’s the two-footed start at the front of the block. This version is simpler and often used by swimmers who want consistency. It doesn’t create as much forward momentum, but it can be very reliable under pressure.
Step Forward Relay Start: The Foundation of Great Timing
Let’s walk through this the way we teach it on deck.
Everything begins with the follow through. Your arms extend forward, and you track the swimmer coming into the wall. This isn’t just for show—this is your timing system. You’re reading their speed, their stroke rhythm, and how they’re approaching the finish.
As they hit their final stroke, you move into the step forward and arm swing. This is where most swimmers either gain speed…or lose it. As your back foot steps forward, your arms should swing back and then load up. That backward swing is critical. It builds momentum so that when your arms fire forward, your whole body follows.
From there, you move into the entry phase. Both feet are now aligned, your knees are bent, and your body is ready to explode forward. Your arms snap into a streamline as you leave the block, setting up a clean and powerful entry into the water. A clean entry is critical in swim relay starts—your entire body should enter through one point to maintain the speed you created on the block. Top swimmers typically enter the water at about a 30-degree angle to balance distance and speed.

Creating Momentum (Where Most Swimmers Go Wrong)
Let’s be honest—most swimming relay starts look a little flat.
That usually comes down to one thing: lack of momentum.
Momentum isn’t just about pushing hard. It’s about sequencing. Your arms and legs have to work together. When the arms swing back and then drive forward, they pull your center of mass with them. At the same time, your legs need to step and push aggressively, not softly.
The best relay starts feel like a chain reaction. The arms load, the legs drive, and the body launches forward in one continuous motion. When that timing clicks, the start feels almost effortless—but incredibly fast.
Timing Off the “T” — But Reading the Swimmer
Most swimmers are taught to use the “T” at the bottom of the pool as a visual cue—and yes, it helps. But here’s the nuance most people miss…
You’re not just reacting to the wall. You’re reacting to the swimmer.
As they approach the T, you prepare. But your actual movement should match their speed. A swimmer charging into the wall will require an earlier trigger. Someone fading into the finish forces you to delay slightly.
That’s why great relay starters aren’t just watching—they’re reading the race in real time.
The Incoming Swimmer’s Role (This Is a Team Skill)
Relay starts don’t happen in isolation.
If the incoming swimmer glides into the wall, everything falls apart. Timing gets thrown off, momentum disappears, and the outgoing swimmer is left guessing.
A strong relay exchange requires the incoming swimmer to maintain speed all the way through the finish. No hesitation. No coasting. Just a committed, aggressive touch.
When both swimmers are in sync, the exchange feels seamless—like the race never stopped.
Relay Start DQ Rules (Don’t Get Burned)
Now let’s talk about the part no one wants to think about—disqualifications.
In relay starts, your feet must remain in contact with the block until the incoming swimmer touches the wall. If you leave early, even by a fraction, your team is disqualified.
At the elite level, swimmers are aiming for reaction times somewhere around 0.05 to 0.20 seconds. That’s the sweet spot where you’re maximizing speed without risking a DQ. Once you start getting too close to zero, you’re gambling.
And here’s the reality—most DQs happen not because swimmers are too aggressive, but because they’re guessing instead of timing.
Watch this example from an age group meet—this is EXACTLY where things can go wrong (and right):
The excitement of a meet can make it tempting to jump early—but a DQ isn’t worth it. Use that adrenaline, don’t let it use you.
Coaches — this is where you build discipline.
Swimmers — this is where you earn trust on your relay.
Step Over Starts and Two-Footed Options
As swimmers become more advanced, many start experimenting with step over relay starts. These can create more forward momentum and lead to faster entries—but they also require sharper timing and better coordination.
Here’s an important detail most swimmers overlook…
Step over relay starts can only be performed on blocks with wedges. That wedge allows you to generate the forward drive needed for the movement. Without it, the technique loses its effectiveness.
Key Steps for Fast and Legal Swim Relay Starts
To bring everything together, here are the key steps every swimmer should master for fast, clean, and consistent swimming relay starts:
| Step | Key Focus | What It Means |
|---|---|---|
| 1 | Understand the importance | Small time gains can decide races |
| 2 | Choose your start style | Step forward, step over, or two-footed based on consistency |
| 3 | Track the incoming swimmer | Read speed, rhythm, and distance to the wall |
| 4 | Use your arms for timing | Establish rhythm before initiating movement |
| 5 | Load momentum | Use the arm swing to create power before takeoff |
| 6 | Connect arms and legs | Create one smooth, explosive movement |
| 7 | Time off the swimmer | React to speed, not just wall position |
| 8 | Read the finish | Adjust timing based on how the swimmer approaches |
| 9 | Execute as a team | Both swimmers must stay aggressive and in sync |
| 10 | Stay fast and legal | Keep feet on the block until the touch to avoid DQ |
The Bottom Line
Relay starts are one of the easiest ways to gain free speed in a race. Get your timing right, build real momentum, and trust your teammate—and you give your relay an immediate advantage before the race even unfolds.
Next time you’re at the pool, keep it simple. Focus on your arm swing, pay attention to how and when you move, and watch the swimmer—not the wall. The more you train your timing, the more natural and automatic your relay starts will become.
