#MILOS, GREECE
THE ‘APHRODITE’ EDITION
29 MAY - 1 JUNE 2026
A incredible opportunity to snap up one of three "wild card” spaces for a once in a life time opportunity to join our Pioneers’ Founders event in Milos, Greece.
As returning swimmers and special invitees, you are at the heart of shaping the future of the UltraSwim 33.3 series. Our pioneering events open up exciting new venues, help refine our courses, experience new accommodation choices and evolve our logistics—all in an intimate setting of a maximum 20 swimmers, reminiscent of our very first #1Montenegro in 2022.
You’ll experience the event alongside the founders and core team, with more time to connect, share stories and be part of the journey.
While smaller events may come with fewer options, they offer invaluable depth, access and community. Safety standards remain uncompromising, the ULTRA+ experience retains its essence, and yes—post-swim massages are included for everyone!
Join us to help build what comes next, and be part of UltraSwim 33.3 at its most personal, purposeful, and inspiring.

OUR HOST VENUE
Milos is best known as the "Island of Colours" in the Cyclades, famous for its otherworldly, volcanic landscapes, especially the moon-like white rock scenery of Sarakiniko Beach. It is renowned for having more beaches than any other Cycladic island, unique, colourful fishing villages like Klima and as the location where the Venus de Milo statue (Aphrodite) was discovered.
WHERE WILL WE SWIM?
The course takes us around the dramatic landscapes of the volcanic island of Milos in the Cyclades islands of Greece. From coloured rock to lunar landscapes, brilliant blue bays and impressive offshore rock formations, this venue is a wonderful blend of traditional Greek hospitality, wild nature and incredible swimscapes.

TRAVEL AND LOGISTICS
Travel and Logistics
Fly to Milos Airport (MLO) from Athens with regular short domestic flights operated by Sky Express and Olympic Air — the most straightforward route for most swimmers travelling to Milos. International travellers can connect easily via Athens, and if you haven’t yet explored the iconic Acropolis of Athens, this is the perfect excuse to extend your trip!
Alternatively, you can travel by high-speed ferry from the Port of Piraeus, with several daily sailings to Milos (journey time approximately 2.5–4 hours depending on service) or fly to neighbouring Santorini or Mykonos islands and take a ferry to Milos. See our Travelbook for more details.
Arrival:
Arrive into Milos Airport (MLO) ideally in the morning, or no later than 16:00 on Thursday 28 May, 2026 to allow time for transfers and event registration.
Departure:
Book return flights from Milos from 1400 onwards on 1 June 2026. Earlier departures may mean missing the final swim — and the chance to officially become a 33.3er!
