#15GREECE

THE ‘MAMMA MIA’ EDITION
18-21 SEPTEMBER 2026

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.

Welcome to Greece’s greenest island, Skopelos in the Sporades archipelago - home also to the cult film Mamma Mia! You’ll be singing Abba songs whether you like or not all the way around!

This racecourse takes us around the unspoilt wild coastlines, both exposed and sheltered from a regular strong north wind and of course, passing the famous filming locations like the clifftop island church Agios Ioannis
 
The water temperature is expected to be between 22-26°C

Unique to our Greek venue

  • Swim between film set locations of the Mamma Mia! film! …our 2024 Pioneer event fave spot? the Mamma Mia church finish line.

  • Our main hotel base, Adrina Resort, family owned and run, hosted the film stars…but more importantly we feel, is that its off-grid with own solar electricity, and installed a filtered water supply just for us (no need for the plastic bottles prevalent in Greece!)

  • Warmest water temperatures of all our events by quite a few degrees.

  • At least one island to island crossing planned

  • Statistically the windiest venue too, but also the warmest.

  • Fly via Athens to visit the Acropolis, or direct in to Skiathos the next door island.

  • Optional night swim, weather permitting.

OUR HOST VENUE

When you think of Greece, Skopelos is certainly the type of place that comes to mind, with stunning crystal clear waters and secluded coves, this picturesque venue has so much to offer. We’ll be staying at the family-run waterfront Adrina Hotel in the tiny fishing village of Panormos (originally settled in the 8th century BC), in the heart of the Aegean sea as our swimmers prepare to take on UltraSwim 33.3 surrounded by the tranquil beauty of this unique venue.

WHERE WILL WE SWIM?

This course* is the most remote route in our Epic Adventure Swim Race Series™, with swimming past beaches and through bays that are only accessible by sea - Included in the plan is a channel crossing from the nearby island of Alonissos, and swims on all sides of the island.

SWIMMING CONDITIONS

This is our warmest water event, 22-26C expected most years! Skopelos has wild coastlines both exposed and sheltered from the strong northerly winds and the island's waters can be mirror calm or roughed up by the big north wind that can blow at any time. There is of course always the risk of September storms - be ready for a bit of everything as we aim to circumnavigate as much as possible of this beautiful, undeveloped island. The definition of adventure!

TIME TO CHOOSE!

1. SELECT A SPORTING FORMAT

CLASSIC

33.3

The Classic

The distance of the iconic English Channel spread over a long weekend. This is the ultimate challenge. Push yourself and join the ranks of the 33.3 finishers! By selecting this option you will swim the entire 33.3km distance solo, over 5-7 swims, across 4 days. Any determined open-water swimmer can do this!

BUILD

22.2

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 22.2km BUILD option is often a great starting point. Day 3 will always be less than the full 10km marathon the 33.3ers will tackle.  See HERE an example of the BUILD 22.2 and DISCOVERY 11.1 plan.

DISCOVERY

11.1

An introduction

This option allows you to discover the magic of UltraSwim 33.3 without the pressure. You will swim a short 2-3km distance each day and get to know our event as you build towards the main 33.3km distance. However, our recommendation will always be to enter the the 33.3 CLASSIC and swim what you can each day - you might surprise yourself!

TRAVEL AND LOGISTICS

Fly directly to Skiathos (JSI) from several European cities, with twice-daily 40-minute flights from Athens with SkyExpress and Olympic Air - the most likely way in and out for most swimmers. If you haven’t visited the Acropolis, now is the perfect opportunity! Weather permitting, we'll whisk you by water taxi from Skiathos to the picturesque beach of Hotel Adrina. Alternatively, choose the scenic land and ferry route from various ports north of Athens, as well from Thessalonika to the north - exact timetables published in May. 

Arrival: Land at Skiathos airport ideally in the early morning or by 14:25 latest on the Thursday 17th September.

Departure: Leave from Skiathos airport anytime from 1430 on the 21st September. If you take an earlier flight you may not be able to finish the final swim and become a 33.3er!
