10 Race Day Tips for Open Water Swimming Events

By Swimtrek , 21 August, 2026

From spectacular coastlines and island-hopping adventures to open water events across the globe, we’ve helped swimmers of all abilities experience the freedom and excitement of swimming in open water. Along the way, we’ve learned a thing or two about preparing for an open water swim event. Whether you’re a newbie or taking on your next big challenge, here are 10 race-day tips to help you swim confidently and most importantly, enjoy the experience.

1. ARRIVE WITH TIME TO SPARE

Rushing before an open water swim is an easy way to arrive at the start line feeling flustered.

Give yourself plenty of time to register, change, find the start and soak up the atmosphere.

Top tip: Read all of your pre-race information so you know what you need to do on the day and what you can do ahead of race day.

2. GET YOUR WETSUIT ON PROPERLY

A well-fitted wetsuit should allow good freedom of movement around your shoulders rather than feeling as though it’s pulling your arms down.

If you’re wearing a wetsuit (be sure to check your race regulations with regards to this), take time to work it gradually up your legs and body before pulling it over your shoulders.

Top tip: A little lubricant around areas prone to rubbing particularly your neck can also make the swim much more comfortable.

3. WARM UP BEFORE YOUR GET IN

You might not have the opportunity for a swim warm-up, but you can still prepare your body on land.

Gentle arm swings, shoulder movements and a little mobility work will help get you ready.

Top tip: Keep your warm-up dynamic rather than tiring yourself out. Focus on loosening your shoulders, activating your upper body and gently raising your heart rate.


4. ACCLIMATISE BEFORE YOUR RACE

The first moments in open water can feel surprisingly intense, particularly when the water is cooler than expected.

Taking a little time to acclimatise can help your body adjust to the temperature and make the start of your swim feel more comfortable.

Top tip: When you enter, give yourself a moment to settle. Get your face wet, breathe out into the water and establish a comfortable breathing rhythm.

5. START AT YOUR OWN PACE

It’s easy to get swept along by the excitement of an event start. Resist the temptation to sprint away unless that’s genuinely part of your race plan.

Starting slightly easier and building into your pace will usually make for a much more enjoyable swim.

Top tip: If you’re nervous about swimming in a group, positioning yourself towards the side or back can also give you a little more space.

6. SIGHT REGULARLY

Unlike the pool, there’s no black line underneath you to follow.

Look forward regularly to check your direction, using the course buoys and larger landmarks where possible.

Top tip: A quick sight every few strokes can prevent you drifting off course and swimming unnecessary extra distance.

7. TAKE THE BEST LINE FOR YOU

The shortest route isn't always the fastest route.

Currents, tides, wind, waves and other swimmers can all influence the best way around a course. Sometimes following the pack makes sense; at other times, taking a slightly different line can give you clearer water or make better use of the conditions.

Top tip: If it’s busy around a buoy, taking a slightly wider line can sometimes be quicker and considerably calmer than getting caught in a cluster of swimmers all fighting for the same piece of water.


8. USE DRAFTING TO YOUR ADVANTAGE

Swimming behind or alongside another swimmer can reduce the effort needed to maintain your pace.

By positioning yourself in their slipstream, you can reduce resistance and settle into a steady rhythm.

Top tip: If you find someone moving at a similar speed, try settling behind their feet or alongside their hip to make the most of the draft.


Coaching Blog


9. IF YOU FEEL ANXIOUS, SLOW THINGS DOWN

Even experienced swimmers occasionally have moments when open water feels overwhelming.

If this happens, ease your pace and focus on a long, relaxed exhale. Switch to breaststroke if that helps you regain your bearings and rhythm.

Top tip: Know the event's safety procedures and follow the instructions of the safety team if you need assistance.


Coaching Blog


10. REMEMBER TO LOOK AROUND

Times and distances matter, but some of the best open water memories come from simply enjoying where you're swimming.

Whether you’re surrounded by dramatic coastline, clear blue water or fellow swimmers taking on the challenge, remember to soak it all in.

Top tip: Find your rhythm, enjoy the atmosphere and take a moment to appreciate what you're doing.

WHERE WILL YOUR SWIMMING TAKE YOU NEXT?

One of the joys of open water swimming is that there is always another stretch of water to discover.

Your next swim could see you island-hopping in Greece or Turkey, exploring a spectacular coastline like Croatia's Dalmatian Coast, or swimming between the Caribbean islands of Nevis and St Kitts. Or maybe you'd like to prepare for your next swim challenge with one of our Open Water Coaching Camps.

Wherever you swim next, take the confidence and experience you've gained in your swimming event with you.
