There’s something electric about the start of an ocean swim. The buzz on the sand, the sound of the horn, the surge of bodies hitting the water all at once. It’s exciting, chaotic, and if you get it right, it can set up your entire race.

Get it wrong, and you can find yourself stuck in the washing machine, swallowing water, and chasing feet from the very first stroke.

Whether it’s a beach start, deep water start, or rolling entry, mastering your start is one of the simplest ways to swim smarter, not harder.

Beach starts: Speed, timing & dolphin dives

Beach starts are where things get real, fast. You’re sprinting, navigating waves, and trying to find clean water before settling into your stroke.

Nail your entry

Don’t just charge blindly into the water. Watch the sets before the start and pick your moment. A well-timed entry can save you energy and keep you out of trouble.

Dolphin dives done properly

Dolphin dives aren’t just for show; they’re one of the fastest ways to get through shallow water.

• Dive forward, not up
• Keep it low and streamlined
• Use your arms to pull through the water
• Transition to swimming just before it gets too deep

Done well, dolphin diving gives you a huge advantage over swimmers who are wading or stumbling.

Timing waves vs charging blindly

Running straight into a breaking wave will stop you dead. Instead:

• Dive under oncoming waves
• Or pause half a second to let a wave pass
• Then accelerate through the gap

Smart swimmers read the ocean. Fast swimmers respect it.

Deep water starts: Position is everything

Deep water starts remove the chaos of the beach, but replace it with something just as important: positioning.

Find Your Line

Before the start:

• Line yourself up with the first buoy
• Use landmarks behind it (headlands, buildings)
• Avoid starting too wide unless you want clear water

Position for clean water

If you’re confident and quick, start closer to the front and centre.

If you prefer space, start slightly to the side or a row back.

There’s no prize for getting boxed in early.

Always a strong first 200m

The first 200-300m is important. It’s your chance to:

• Establish your position
• Find good feet
• Avoid getting stuck in slower traffic

This doesn’t mean sprinting flat-out, but it does mean being assertive.

Rolling Starts: Controlled chaos

Rolling starts are becoming more common, sending swimmers off in small waves rather than one big pack. It’s calmer, but still tactical.

Start smart, not fast

You don’t need to sprint like a beach start, but you do need to:

• Settle quickly into your rhythm
• Avoid drifting into slower swimmers ahead
• Stay aware of faster swimmers behind

Use the gaps

Rolling starts often create natural gaps:

• Swim into space early
• Find clear water instead of congestion
• Build momentum without contact

Stay mentally switched on

Because the start is less chaotic, it’s easy to switch off. Don’t. Positioning still matters, and so does your first few minutes of swimming.

Avoiding the washing machine

No matter the start type, the biggest mistake swimmers make is getting caught in the chaos.

How to stay out of trouble

• Pick your position wisely, not too aggressive, not too passive
• Keep your stroke strong and consistent; hesitation causes collisions
• Lift your head when needed, awareness beats panic
• Commit to your line; second-guessing leads to zig-zagging

If you do get caught in the washing machine

• Stay calm
• Widen your stroke slightly for space
• Focus on exhaling and resetting your rhythm

It always settles. The key is not letting it rattle you.

Bringing it all together

A great ocean start isn’t about going the hardest. It’s about going the smartest.

It’s reading the conditions before you hit the water.

It’s executing the right skills, whether that’s dolphin diving, positioning, or pacing.

And it’s putting yourself in the best possible spot to swim your race, not someone else’s.

Because in open water, the first few minutes don’t just start your race… they shape it.
