IS ULTRASWIM 33.3 FOR ME?

Appealing to who, you?

  • Experienced open water swimmer looking for a new challenge, more than just a one-day event

  • English Channel hopefuls wanting to test themselves on the same distance but spread over 4 days

  • Swim-runners unable to run!

  • Pool swimmers looking to widen their horizons to open-water… 10km race swimmers fed up with laps around buoys!

  • Triathletes wanting to extend their swimming distances, or no longer able to train for all 3 sports!

  • Competitive swimmer or not, but want to experience some adventure swimming with a group of like-minded people from all over the world

  • Coach or Club looking to run a group challenge/event without the hassle of organising it!

“This event isn’t for everyone, but everyone can do it”

Mark Turner, Founder of UltraSwim 33.3

You don’t have to be an elite swimmer to be a winner at UltraSwim 33.3 - any determined competent swimmer, with the right preparation, can succeed and join the exclusive list of 33.3’ers! 


Every finisher is a winner, and even if you don’t make all the finish lines, you’ll be enormously respected for what you’ve achieved, regardless. 


The fastest swimmers are often the loudest too, so it's easy to get put off by the Strava or Facebook chat about the distances shared, the times achieved, the pace the faster swimmers are nailing… but UltraSwim 33.3 attracts and supports in equal measure a full range of swimmer profiles. 


At our events we’ve seen every kind of swimmer - from ex-pro/elites at one end of the spectrum, to those at the start of their open water swimming experience at the other - and everything in between! 


We understand everyone is at different points in their swimming journey and our team is here to help. If you’ve got the ambition, we’ve got your back. Remember, you can contact our team at any time. 


In the meantime, why not take a look at some of our swimmer’s previous concerns below, and our team’s responses. 

“I don’t want to spend too much” 

We understand that events can be a luxury, that’s why we’ve curated three different packages, based on financial flexibility. Choose between our ULTRA, ULTRA+ and ULTRA++ packages to decide which is best for you.

“I can’t take too much time off” 

We understand time is also a luxury when it comes to taking part in events. That’s why each of our events promises to be over a long weekend, allowing participants to get back to their day-to-day lives as soon as possible (just feeling awesome!) 

“I don’t want to leave my family” 

You don’t have to! In 2023 we successfully set up our F3 package for Friends, Family and Fans. For an additional fee, you can add your family onto your trip where they can enjoy lazy mornings, boat trips, join the lunches, be there for you on the finish line and much more! 

“I’m not sure I’ll make it” 

If we had a penny for every time we heard this and then proceeded to see all the happy faces on our finish line… as long as you meet the criteria, there is absolutely no reason you won’t make it to the finish lines. Our team of coaches are here for you, and there’s always incredible amounts of encouragement among the swimmers at each event. We’ve got your back but you also have each others! Don’t let doubt stop you. 

“I’m worried I wont’ have enough time to train”

Like all challenges, making time to train is important. That’s why we have an expert support team available to you, through our coaching team at Envol, to our nutricion partners Precision Fuel & Hydration. We can also put you in touch with fellow 33’ers from your area so you can push each other and train together. 

“What about wildlife such as jellyfish and sharks” 

Whilst there can’t be any guarantees, in three separate events (each across five days) only one jellyfish has been spotted once! No one taking part has ever had an incident, however this is mother nature and we are out in the wild! Generally the situation on the eastern side of the Adriatic Mediterranean is different to that of the west so the risk is a lot lower.
