#10MONTENEGRO
THE ‘FJORDS TO THE SEA’ EDITION
3-6 OCTOBER 2025
Step out of your comfort zone with UltraSwim 33.3
33.3km (English Channel distance) spread over 4 days, 6 swims.
Welcome to your next big challenge.
UltraSwim 33.3 #10Montenegro is the original Epic Adventure Swim Race™. The founding event of our series, we will return for a fourth time in 2025 for the iconic ‘Fjords to the Sea’ Edition.
Swimmers can look forward to the challenge of a country to country channel crossing from Croatia to Montenegro, swimming through an abandoned submarine pen, around a old fortress island and of course the famous Blue Cave (pictured above, startline of the marathon 10km swim if the sometimes choppy Adriatic coastline weather permits).
Step out of your comfort zone with us and discover the true meaning of epic adventure swim race™!
THE VENUE
One of the smaller countries of the Balkans, Montenegro offers both wild mountains and deep fjords, as well as a rugged Adriatic coastline, which in turn produces a variety of conditions - perfect for an Epic Adventure Swim Race™! Montenegro was our founding event back in 2022 and remains on the UltraSwim 33.3 calendar due to its appeal to swimmers. We stay near the entrance to the Bay of Kotor and enjoy the services of our brilliant partners at the Lazure Hotel & Marina in Herceg Novi.
THE COURSE
This course* around the Lustica peninsula offers a few particularities - including a start line inside a giant ‘blue’ cave, a full loop of an old fortress island as an untimed section, and a race mark inside an abandoned submarine base from the Yugoslavia era. The course layout itself is of course point-to-point with the majority of starts and finishes in the water.
*This course is indicative and by no means final
SWIMMING CONDITIONS
At the end of the summer season, shorter days and variable weather, #10Montenegro can present a variety of conditions. Expect anything from summer-like afternoon heat with flat calm waters, to stormy conditions we will safely navigate together. The combination of the wild Adriatic coast and protected fjord areas gives us a few options in case of windy conditions and rough seas - but certainly don’t expect flat calm every day. Difficult to predict currents have added some challenges in our previous editions - but hasn’t stopped even the slower swimmers from nailing their 33.3 challenge and earning their Finisher droplets!
The water temperature is expected between 20-22°C with occasional small patches around 15-18°C (as isolated cold springs popup). These conditions are suitable for both skins and wetsuits.
TRAVEL AND LOGISTICS
Arrive in stunning Dubrovnik, Croatia, by scheduling your flight to land no later than 14:00 on Thursday, October 2nd. We'll provide seamless land transfers to your destination. Alternatively, opt for a direct flight to Tivat, Montenegro, with arrival no later than 15:00, where we transfer you by boat straight from the airport if needed and with no border to cross! You can always extend your stay to explore historic Dubrovnik, and the rugged beauty of the Black Mountains, or the enchanting fjords of Kotor Bay.
Departure flights as early as 16:00 on Monday 6th offer flexibility for planning if you need to rush home!
“I was blown away by the calibre of this event and I’ve done plenty. The pre race comms, course , location, hotels., logistics and event delivery team were 1st class. Course distances were ideal. Course was perfectly marked and the event organisation was flawless, despite challenging weather conditions. Wide range of abilities from racers to those just wanting to complete. Whatever your standard, everyone was treated the same and encouraged and supported. Other participants were great and I made a lot of friends. I’ll do another without any hesitation. It hits the sweet spot between being really challenging but achievable. This is THE newcomer event in the swim space and it nails it. I expect this to be grow and be massively popular. Highly recommended!”
