Every October, the stunning island of Santorini transforms into a haven for athletes and adventure seekers from around the world. The Santorini Experience 2026 invites participants to challenge themselves amidst the breathtaking landscapes of Greece's most famous volcanic island.
From trail running to open-water swimming, this event is more than just a competition—it's an opportunity to experience Santorini's unique geography in a way that goes beyond ordinary sightseeing.
"Santorini Experience is not simply a race weekend. It is a chance to move through Santorini’s villages, admire the Aegean from the caldera edge and experience the volcanic environment in a way that ordinary sightseeing cannot match."
