Are you going to travel to Lisbon, Cascais or Sintra and want to continue your training?

In this swimming session we will take you to swim in the Ironman Cascais swimming course.

With historic houses, palaces and fortresses from past times, Cascais is one of the most beautiful places designed for a triathlon.

We'll meet at Praia da Duquesa, where we'll start our swim session.

Then we will swim along the protected Cascais Bay, in a course of rare scenic beauty.

According to your swimming level we can adapt the swimming distance.

We will finish the training session on the beach to take a fresh water bath, from where you can make the transition to the cycling or running segment.

Are the swim sessions individual or in a group?

We offer both options! You can book a personalized 1-on-1 session for focused coaching or join one of our group swims to train with other athletes. Please specify your preference in the checkout page.

Where is the meeting point for the 1h-Swim?

We meet directly on the beach. Our primary location is Praia da Duquesa in Cascais. However, as we are strictly dependent on sea and weather conditions, the location may change to any beach between Oeiras and Cascais.

How will I know the exact meeting location?

After your booking is confirmed, a WhatsApp group will be created with your designated Swim Guide or Swim Coach. This group serves as a direct line of communication to clarify any doubts and to receive the exact GPS coordinates or a pin of where to meet on the sand.

Are there changing rooms or lockers available?

No, there are no official changing rooms or lockers at our meeting points. We recommend arriving with your swimsuit already on. You can usually store your personal belongings in the coach's car, with another swimmer, or ask a local beach café to keep them for you.

Can I shower after the swim?

While there are no indoor facilities, most of the beaches we use have public outdoor showers where you can rinse off the salt water after your session.

Can I rent equipment if I don't have my own?

Yes! We provide wetsuit and safety buoy rentals. Please inform us in advance if you need equipment so we can ensure your size is available for the session.

Is a safety buoy mandatory?

For safety and visibility in open water, the use of a tow-float (safety buoy) is mandatory. If you do not own one, you can rent one from us.

What happens if the sea conditions are bad?

Safety is our top priority. If conditions at the primary beach are unsafe, we will attempt to move the session to a more sheltered spot nearby. If the weather makes swimming impossible, we will contact you to reschedule the session.

What should I bring besides my swim gear?

We highly recommend bringing a towel or a "changing robe," a warm change of clothes, and water. Since we change outdoors, a waterproof bag to keep your dry clothes protected on the sand is also a great idea.

What is the minimum swimming level required for the 1h-Swim?

To ensure you get the most out of this 1h-swim, you should be able to swim at least 200 meters of continuous freestyle. Our sessions are designed to be challenging but scalable for different paces.

What is the cancellation policy for the 1-Swim?

We accept cancellations and provide a full refund or rescheduling options if you notify us at least 24 hours before the start of the session. Cancellations made with less than 24 hours' notice are not eligible for a refund.

What equipment should I bring?

In addition to your swimsuit, goggles, and swim cap, make sure you bring your wetsuit and tow-float (safety buoy).

Will I get individual feedback on my stroke?

Yes, if you book a private swim! The 60-minute sea session is highly interactive. Our coaches move along the beach to provide real-time corrections.

Is there a minimum age requirement?

Our standard swims are designed for adults (18+). However, contact us if you have a teen swimmer interested in joining.

What happens if I can't attend a session I booked?

Please refer to our cancellation policy on the checkout page.

How can I book?

Bookings are made online through our website, with instant email confirmation. We recommend booking in advance as group sizes are small.

How does payment work?

Payment is made in full at a single time.

How many spots can I book at once?

You may book all available spots for yourself and your friends, subject to availability.

    By Romy Lazzara Abril 6, 2026 Highly recommend 🙌
    Highly recommend 🙌 I started private lessons to gain more confidence & learn more about swimming in the open water - my coach Tudor was amazing - very patient, and gave me great tips and advice on technique. I’m feeling a lot more confident & comfortable after 3 lessons and will continue!

    By Maureen Callahan Outubro 13, 2025 Committed to getting me in the water to swim!
    Swim together was incredible! I What’s app them to see if I could do an OWS prior to the Ironman. Andre promptly got back to me to help me set something up. He stayed engaged, back and forth, to see if I could get a 1:1 coach swim. When that didn’t work out he stayed with it and connected me to an intermediate swim group on Sunday. The coach was very helpful and he guided me in uncharted waters (for me). I have connected with OWS groups in many places, Swim Together represented their name in so many ways. Thank you.

    By Kalinka Faria Junho 10, 2023 SwimTogether is the best company of open water swimming
    SwimTogether is the best company of open water swimming. I'm lucky to be Portuguese and the privilege to swim with them twice a week in Cascais. I started two years ago. I already swam in Madeira island in 2022 and Algarve's coast for a week, this year. We swam in amazing and beautiful places which we could never imagine. We always swim safely, with expert guides. I recommend this experience to all the open water swimmers 🙂
