UltraSwim 33.3 #15 Greece

Dive into the breathtaking beauty of Greece’s Sporades archipelago with UltraSwim 33.3 #15, set against the backdrop of the enchanting island of Skopelos—made famous by the beloved film "Mamma Mia!" This idyllic destination promises a swim experience unlike any other, where you’ll find yourself serenaded by ABBA tunes as you glide through crystal-clear waters.
Scheduled for 18-21 September 2026, UltraSwim 33.3 #15 offers swimmers the unique opportunity to explore Skopelos’s pristine coastline and iconic filming locations from the movie. The course weaves between wild stretches of open sea and sheltered coves, thanks to the island's prevailing north wind that shapes the swim route.
Water temperatures are expected to be a warm 22–26°C, making this event one of the most comfortable in the UltraSwim series. Swimmers will enjoy an immersive journey through some of Skopelos’s most recognizable spots, including the dramatic clifftop church of Agios Ioannis—an unforgettable landmark captured on film.
For those looking to extend their adventure, additional challenges include island-to-island crossings from Alonissos to Skopelos and a full circumnavigation around the island. These options provide an extra layer of excitement for seasoned swimmers seeking more ambitious routes.
The event’s base is located at the Adrina Resort—a family-owned establishment that played host to "Mamma Mia!" stars during filming. The resort prides itself on being off-grid, powered by solar electricity and offering a filtered water supply specifically designed for UltraSwim participants—eliminating the need for single-use plastic bottles.
While Skopelos presents some of our windiest conditions, its warm waters make it an exhilarating challenge for swimmers looking to push their limits. The resort’s commitment to sustainability ensures that your participation supports eco-friendly practices while you enjoy a memorable swim experience.
Before heading to Skopelos, take the time to explore Athens and marvel at the ancient Acropolis—adding another layer of cultural richness to your journey.
