OUR HOST VENUE
Montenegro was our founding event back in 2022 and remains on the UltraSwim 33.3 calendar due to its appeal to swimmers. We base the event near the entrance to the Bay of Kotor and enjoy the services of our brilliant partners at the Lazure Hotel & Marina in Meljine, near to Herceg Novi. This gives us access directly to calmer fjord waters, and very quickly we can be out on the wild Adriatic coast too. Montenegro remains a relatively unspoilt and undiscovered gem of Europe with plenty of scope for continuing your adventure holiday after your swim.
WHERE WILL WE SWIM?
There will be a 7km and 10km point to point swim…
SWIMMING CONDITIONS?
At the end of the summer season, as autumn begins to settle in, the Costa Brava offers a mix of conditions that can vary from day to day. Expect anything from warm, sunny afternoons with calm, clear waters to cooler, windier periods that can create choppier seas. The rugged coastline, with its mix of open stretches and sheltered coves, gives us flexibility to adapt routes depending on the conditions.
Winds such as the Tramontane can occasionally pick up and add an extra challenge, and while currents are generally mild, they can still be unpredictable at times. That said, these elements are all part of the adventure and haven’t stopped swimmers of all levels from successfully completing their challenge and earning their Finisher droplets.
The water temperature is expected to be between 19–22°C. These conditions are suitable for both skins and wetsuits, depending on your preference.

TIME TO CHOOSE!
1. SELECT A SPORTING FORMAT
33.3/2 BUILD
BUILD your distance
This is the perfect build-up to the iconic 33.3km distance. Many swimmers have doubts (despite often being more than capable) so the 33.3/2 BUILD option is often a great starting point. Swims are almost always less than 5km, as you aim for a 'half' Channel total distance. This is a non-competitive format, no rankings or podiums should be expected. See HERE an example of previous event plans.2. CHOOSE YOUR PACKAGE

“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!”
