A Beginner's Guide to Open Water Swimming

So, you've decided to take the plunge and try open water swimming? Whether you're looking to switch up your swimming routine, train for a triathlon, or just enjoy nature in a new way, open water swimming is an exhilarating experience.  

Open water swimming can also offer many benefits; it can help better your mental health, sleep and circulation, as well as increase your metabolism and boost your immune system. 

 But, before you dive in, it's crucial to know the basics, be armed with swim safety tips and know what kit you need. Let’s get you started on the right foot with this open water swimming guide. 

Open Water Swimming Safety Tips 

Staying safe in open water is non-negotiable. Here’s a step-by-step guide to ensure you stay safe before, during, and after your swim: 

Before You Swim 

  • Check the Weather: Always look at the weather forecast. Avoid swimming in storms, high winds, or extreme cold. 
  • Know Your Location: Familiarize yourself with the swimming area. Are there lifeguards? What are the local hazards (like rocks, currents, or marine life)? 
  • Buddy Up: Never swim alone. Having a friend with you can be a literal lifesaver. 
  • Inform Someone: Let someone on shore know where you’re swimming and when you plan to return. 

During Your Swim 

  • Stay Close to Shore: Especially as a beginner, don't venture too far from the shore. 
  • Wear a Tow Float: Also known as a safety buoy, it makes you more visible and provides something to hold onto if you need a rest. Regularly Check In: Communicate with your swimming buddy frequently. 
  • Listen to Your Body: If you feel cold, tired, or unwell, get out of the water immediately. 

After Your Swim 

  • Warm Up: Dry off and get into warm clothes quickly to prevent hypothermia. 
  • Hydrate and Refuel: Drink water and have a snack to replenish your energy. 



Top Tips for Open Water Swimming 

Now that you know how to stay safe, let’s talk technique! 

The main differences between pool swimming and open water swimming are the lack of walls to push off from, not having swim lanes to guide you in the right direction and not being able to touch the bottom. These are all differences that with time, you can learn to adjust to. You can adjust to these differences by practicing the following techniques:    

Relax and Breathe 

Anxiety can make you tense up. Practice deep breathing to stay calm and relaxed, this will make you swim stroke feel more fluid and make your open water swim session more enjoyable. 

Sighting 

As mentioned before, in open water no swim lanes or lane lines are guiding you in the right direction. To be able to guide yourself in the open water, you’ll need to learn how to sight. This just means practicing looking ahead during your swim to find a ‘marker’ in the distance to guide you.  

Most people spot a tree, or a small landmark, and use that as guidance on where to swim to. You can practice this in a pool by focusing on a spot on the wall at the end of the lane you’re in. Another way to train in a pool for open water swimming is to try and swim in a straight line as much as possible. In open water triathlons, you’re bound to veer left or right and bump into other triathletes, so getting this spot on in the pool beforehand is a good idea. If practicing this for the first time in open water, swim close to the shoreline until you’ve got it right and then venture further into the water.   

Treading water   

There are no walls to kick off from in open water. You’ll probably find yourself treading water a lot when in a lake, or the sea, so it’s best to practice treading water in the deep end of the swimming pool.   

Turning   

Often, open water events require participants to turn around a water buoy, sometimes more than once in a race. You can train for this in open water once you’re confident, but it’s a good idea to try this in a pool as well
