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.

  • Anything not mention in the "included" section
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.

    October 5, 2026 Very knowledgeable and a great coach
    I enjoyed my swim at Caxias Beach with Pedro. He is very knowledgeable and a great coach. He gave me some good tips. The area was beautiful and the view of the ocean and city were amazing. I recommend if you are a beginner and want some one to help you learn to swim in open water.

    July 24, 2026 I couldn’t have completed the 20km swim without SwimTogether!
    I honestly couldn’t have completed the 20km swim from Lisbon to Cascais without SwimTogether. The entire team is incredibly professional, welcoming, and passionate about open water swimming. The coaches are outstanding and shared so many valuable insider tips about the course, ocean conditions, and race strategy that made a huge difference on race day. Their knowledge, experience, and support gave me so much confidence before the event. If you’re planning to swim in Portugal or prepare for an open water race, I highly recommend SwimTogether. Thank you so much for helping me achieve one of the biggest goals of my life! 🌊🏊🏽‍♂️

    July 21, 2026 Recomendo muito esta experiência!
    Foi uma aula na baía de Cascais com o professor Tudor Florin, que em pouco tempo me ensinou técnicas eficientes, mesmo fora de água. Além disso, tirou fotos e filmes que me enviou no fim. Recomendo muito esta experiência!
