An introduction to Open Water Swimming


Where can I practice open water swimming?

You can open water swim in lakes, the sea and pools all across the world! As a general rule it is best to check water quality and conditions before a swim and don’t go alone.

If you’re considering taking your first step into open water swimming find out what to expect from a swimming holiday.

How to train for open water swimming in a pool?

There is the perception that open water swimming is harder than a pool because of water conditions, clarity and current. It is undoubtedly more interesting swimming outdoors and from A to B than up and down a crowded chlorinated lane so you may find if you are new to open water swimming that you can achieve longer distances easier than in a pool as you are more engaged with your surroundings. There are safety issues to take into account when swimming in the open water, especially swimming in an area with no lifeguards and we would always strongly advise to not go swimming alone. Make sure someone knows where you are, do not enter water you are unfamiliar with and check locally for information about hidden currents or obstacles in the water. You can access our full training program here which you can follow in the pool or open water to prepare yourself for a SwimTrek trip.

Open water swimming can suggest swimming further distances in big bodies of water as opposed to for the exploration of swimming locations.

Wild swimming generally means that you are not guided and of course this poses some risks. SwimTrek guided open water adventures mean not only that you’ll be able to explore safely but the security of guides means you will be able to visit more remote locations.


Before you book a SwimTrek Trip

All non-swimming guests must agree to our non-swimmer agreement and, for safety reasons, are not permitted on the safety vessels that accompany our swimmers.

How should I prepare for my trip?

You can download our comprehensive Training Plan for all the information that you'll need to get the most out of your holiday.

How long to swim a mile?

Many factors depend on how long it takes to swim 1 mile in open water. The fitness and stroke of the swimmer obviously have a large impact as well as the weather and conditions of the water. The average SwimTrek speed is 15-20 minutes per kilometer which works out at around 29 minutes a mile. For most of our SwimTrek trips we ask that swimmers are able to swim 1km (0.6 miles) in 40 minutes to take part in our swimming trips.

A limited number of single supplement rooms are available on most of our trips, however, it’s also possible to book a ‘Roommate Share’ room, which means that we will match you up with a SwimTrekker of the same gender to share a twin room. Please note that single supplements and roommate shares are both subject to availability.

What will my fellow swimmers be like?

As swimming is a low impact, medium intensity activity, it enables a wide variety of ages and experience levels to take part in our trips. Your fellow guests could include young students, retired couples, solo travellers, groups of friends, experienced open water swimmers or those unfamiliar with life outside the pool. Whatever the makeup of your group, you can be sure that you’ll have a mix of fascinating personalities from all around the world who share a common love of swimming and the great outdoors.

Are there any non-swimming activities?

The number of non-swimming activities varies considerably from one trip to the next, so it’s worth taking a look at the ‘Itinerary’ tab of the trip page that you’re interested in to find out more about what’s involved. Many trips include great walks to and from the start/finish point of our swims, while there is usually also time to see some local sites and enjoy the culture and atmosphere of the location when you’re out of the water.

How often do you cancel a departure?

As a tour operator, there may be times where we need to cancel a departure due to a lack of bookings on a particular date, however, this is an extremely rare occurrence and we consistently run more than 97% of our scheduled departures. If we do need to cancel a particular departure, we will advise all affected guests at least eight weeks prior to the trip start date.

When you are on a SwimTrek trip


How far will I swim each day?

Daily swimming distances vary considerably from one trip to the next. The majority of our trips cover an average of 3-6km per day, usually split between one morning swim and one afternoon swim, however, we also have several Short Swims options and introductory trips with shorter daily swim distances. At the other end of the scale, we also have a number of Long Swims trips and Distance Training Camps which include daily swim distances of 7-8km. Please use the filters on our Trip Search page to find the daily swim distance that is just right for you.

Will I be able to swim the distances in the trip itinerary?

While the daily swim distances may be more than you're used to swimming in a single session, there are a couple of reasons why you may surprise yourself with how far you can swim on your trip. Firstly, while many people are used to doing all of their daily swimming in a single session, e.g. before work, during lunchtime or at the end of the day, by breaking up your daily distance into several shorter swims, often with one swim in the morning and another in the afternoon, most people find that they can cover significantly greater distance than what they expected. Secondly, while going up and down a pool can quickly become monotonous and cause you to end your session early, swimming in the open water means that there's always something interesting to look at, both above and below the water. This often means that you cover much more distance without even realising! Finally, the psychological effect of seeing your target destinations ahead of you, combined with the increased buoyancy that you'll experience in the open water, generally means that it's possible to swim greater distances in the open water than what you could manage in the pool. It's also worth mentioning that every swimming group is accompanied by its own support vessel, so if you do need to take a break at any stage throughout your swim, you're more than welcome to jump on the boat for a rest.

How fast do I need to be able to swim?

We often have a wide range of swimming speeds on a particular departure, with our guests covering 1km in the open water in anything from 10-40 minutes. As a guide, guests should be able to swim a minimum of 1km in 40 minutes. One of the great features of a SwimTrek trip is that we cater for this range of swimming speeds on each departure. At the start of your trip, your guides will carry out an acclimatisation swim with all guests, which will then be used to group together swimmers of a similar speed. Generally, there are 2-3 different speed groups per trip, however, this can vary depending on the makeup of the group on each particular departure. By splitting swimmers into smaller speed groups, we are able to ensure that all guests are swimming at an appropriate pace. Each group is also accompanied by a support vessel at all times.

Do I have to complete all of the swims?

No. This is a holiday, after all! If you need to take a break during a swim you are welcome to jump on the support boat at any time. On the trips where we use kayaks rather than main support boats, your guides will be able to advise you about the various options for getting out of the water and walking different sections of the route, where possible.

Which strokes do people swim?

Although the majority of our guests swim front crawl (freestyle), we often have a number of breast-strokers, too. Having different swimming groups means you can swim whatever stroke you want.

What type of support do we have on the swims?

Every swimming group is accompanied by its own support vessel on each swim. On most trips, these vessels usually consist of one main boat and two inflatable boats, however, on some of our lakes and rivers trips where we are unable to use motorised vessels, our guides accompany swimmers in support kayaks. Your support vessels and guides are there to provide safety cover, drinks and snacks, as well as assist with improving your technique over the course of your trip.

Will we see any marine life?

One of the great joys of open water swimming is that it gives you the chance to appreciate the incredible range of wildlife, natural topography and underwater vistas that most people never get the chance to see. The type of marine life that you may encounter on your trip varies considerably from once location to the next. We’ve been known to swim with everything from curious dolphins and inquisitive seals to laid back sea turtles to exotic fish.


Swim gear and what you need to pack


What to wear for open water swimming?

Some open water swimmers will always swim ‘skins’ in open water - this doesn’t mean naked (although maybe sometimes it does) but in a light swim costume such as you would wear in a pool. If you want to be able to stay in cooler water longer or feel more comfortable with some protection then a wetsuit is a good option. Wetsuits come in various sizes and it’s important to get one that fits correctly to work effectively. You should still wear a swimming costume under a wetsuit for open water swimming. If swimming in really warm climates it can be a good idea to wear a rash vest that is a lightweight skin tight top that will protect your skin from harmful UV rays while swimming. Swim shoes can protect you from rocky terrain under and above water - or like us a SwimTrek HQ help you get down to the sea on the rocky Brighton beach!

What should I bring with me on a trip?

For detailed information on what we recommend that you bring with you on a particular trip, please see the ‘Trip Info’ tab of the relevant package page. You can also download the Trip Notes from the ‘Trip Overview’ sidebar of each package page. We will provide you with a SwimTrek swim hat on every trip.

Will I need a wetsuit on the swims?

Every swimmer has a different sensitivity to cold water, which makes it difficult to give a generic answer to this question. 360guide have a fantastic article to help you decide whether you may need to wetsuit or not in certain water temperatures and, if so, which type and thickness might be right for you. Many of the locations we operate in can be remote and it will be hard to find a wetsuit appropriate for swimming. If in doubt, we recommend that you bring a wetsuit with you from home. Throughout a week of swimming, your body will become more susceptible to the cold and you will feel the water affecting you more. We recommend bringing a suit that you have tried and tested and are happy swimming in. If in doubt about whether you should take a wetsuit with you on your trip, we recommend that you follow our theory that “it’s better to have it and not need it than need it and not have it!” My wetsuit hire offer a range of different thickness swimming wetsuits on a 14-day, 28-day or full-season hire basis, meaning that you can get some swims in prior to heading out to location. Use the code ‘swimtrek’ when booking your wetsuit hire in order to receive a special discount.

Which wetsuit for open water swimming

The best wetsuit for open water swimming depends a lot on personal preference, reason for wearing the suit and the conditions of the water in which you are swimming. Almost all wetsuits come in standard sizing by gender - XS, S, M, ML (medium long), L, XL. The best way to find out which is right for you is to try them on. A wetsuit should be tight but able to do up and undo by yourself. Here’s our review of some swimming wetsuits in conjunction with the Open Water Swimming Society.

Can I use a snorkel on the swims?

Whilst snorkels are permitted on our organised trips, swimmers are advised to discuss this with their guides at the welcome meeting. It is incredibly vital that if you choose to wear a snorkel, you continue to listen for instructions or warnings which may be issued by the guides and to maintain sighting at all times.

How to put on a swim cap

A tried and tested method here at SwimTrek HQ is to get a fellow swimmer to help you out by holding the front of the hat while you put any hair on top and pull it over. If you’re swimming solo then first make sure any hair you have is tied up and hold it in a bun on top of your head with one hand. With the other hand stretch the hat from front to back of your head stuffing your hair in as you go. Once the hat is firmly on your head covering your hair you can push any stray wisps under with your fingers. Move the hat around until it is comfortable, strap on your goggles and away you go! If you have trouble getting the hat to stretch or to grip onto your head putting a drop of water into the hat and swishing it around can help.

Can you swim with a fitbit?

No, most styles of a fitbit are described as strictly water resistant, meaning it will withstand a splash of rain but is not designed to be submerged. Lots of general fitness trackers are unsuitable for swimming so we would advise purchasing a specially made swim tracker.


Swimming Technique and Fitness - Answers from SwimTrek guide Ricky!


Will I have a chance to improve my swimming technique?

Many people take part in our trips in order to improve their open water swimming technique. Whether you’re new to the open water or have been out of the pool for your whole life, our guides will work closely with you to get the most out of every stroke that you take.

Is open water swimming good for you?

Swimming is a great exercise for your body and mind. Unlike running or a gym workout, swimming is very kind to your body as it doesn’t put stress on your bones due to the water buoyancy. There has also been much research into the positive effects that open water swimming can have on mental health - being in the water allows you to take a break from the busy pressures of modern life.

Does swimming build muscle?

Swimming can improve fitness and building muscle is a side effect of getting fitter. If your aim is to predominantly work on building muscle then swimming will not be as helpful as other activities. The amount of muscle you are likely to build will depend on the way you swim. A causal swim is unlikely to help you bulk up however high intensity interval training workout in the water will make your muscles stronger. In relation to our SwimTrek trips other than events and coaching trips you are not under pressure to workout or swim anymore than you feel comfortable.

Is swimming cardio?

Swimming does work your cardiovascular system and it does use most of the muscles of the body, working your heart. Once again it depends on the amount of energy you put into your swims. On our trips it is likely that your fitness will improve, especially if you are generally a pool or outdoor swimmer that swims less than 2km a day. Lots of our swimmers come back to their clubs or swim groups and find that they can swim with much more stamina and ease than before their SwimTrek trip.

Is swimming good for toning?

If combined with a healthy lifestyle and you are swimming frequently then it can help you to tone. Depending on your fitness level, body type and the swim workouts that you are achieving will determine how it will change your body.

What muscles does swimming work?

One of the great aspects of swimming is that it works the muscles all over your body. With regards to good technique and what stroke you are doing these will differ. For freestyle we try to work the lats - the larger muscles rather than the smaller muscles in the shoulder, your obliques on your core along the side of your stomach. The leg muscles glutes are worked with kicking. Breastroke swimmers with the wide legs movements work the abductor and adductor thigh muscles.

What to eat before swimming?

Contrary to the popular belief old wives tale that you have to leave an hour after eating to swim or you’ll drown there’s no evidence of this being true however swimming on a full stomach can make you feel sluggish and unwell. However it is best not to try to not eat too much before swimming if your blood is busy digesting then it will affect your session. Don’t think too much about eating before a swim as most swimmers know you’ll be ravenous as soon as you leave the water.
