TÜRKİYE AÇIK SU YÜZME YAZ ŞAMPİYONASI VE MİLLİ TAKIM SEÇME YARIŞMALARI

In Turkey, the waters off İçmeler beach host the Türkiye Açık Su Yüzme Yaz Şampiyonası ve Milli Takım Seçme Yarışmaları, an open water swimming championship held in the sea at Marmaris in the province of Muğla. Organized by the Türkiye Yüzme Federasyonu, the championship takes place in June, drawing competitive swimmers to the sheltered coastal basin for an intense multi-day program. Entering the sea from the beach, swimmers face courses marked out over the open bay, testing speed, endurance, and pacing under summer skies. The competition program unfolds over four consecutive race days, structuring distances to test different specialties from sprints to marathon endurance. The schedule stages 7.5 km and 3 km events on the first day, followed by 5 km and 2 km races on the second day.

The third day brings 3 km and 1 km heats, leading to the culminating 10 km marathon contest on the fourth day. Over this sequence of distances, competitors must carefully manage their energy across repetitive loops in the saltwater. Every race follows a marked buoy course where tactical positioning and navigational precision are essential. Competitors are required to round every turn buoy properly to complete their distance; failing to round a buoy results in an immediate red flag and disqualification from the event. For those contesting the grueling 7.5 km and 10 km marathons, feeding is permitted at a dedicated station clearly laid out directly along the race circuit, allowing swimmers to take on essential nutrition without losing their drafting rhythm.

Strict competitive parameters govern each division, giving the championship high stakes as an elite trial. For senior entrants over the age of twenty, participation requires proven credentials: competitors must have completed a previous 10 km national open water championship or contested an 800-meter or 1,500-meter event at the Turkish Swimming Championships within the preceding three seasons. In addition, the event serves as the official qualifying trials for the European Junior Open Water Championships, granting selection berths to the top two finishers in the 5 km for ages 14 to 15, the 7.5 km for ages 16 to 17, and the 10 km for ages 18 to 19. Time limits are strictly enforced across all fields to maintain elite competition standards.

In the 5 km race, swimmers falling more than ten minutes behind the first finisher are ruled out of the time limit, while in the 7.5 km and 10 km events, the cut-off window is set at twenty minutes after the winner touches the finish pad. Younger competitors in the 11, 12, and 13-year-old categories face strict overall cut-off times: 30 minutes for the 1 km, 50 minutes for the 2 km, and 60 minutes for the 3 km contest.

Marmaris National Park: peridotite slopes and marine life

Marmaris National Park is a coastal environment recognized globally as a priority conservation area for marine biodiversity. The marine ecosystem protected within the park supports a diverse population of 35 documented fish species that inhabit these waters.

Marmaris Bay: ancient fleets and the Fake Strait

The bay itself is sheltered by Heaven Island, which is tethered to the mainland by an isthmus known locally as the Fake Strait. Thanks to this geological configuration, the waters of Marmaris Bay form a vast protected haven that historically offered refuge to major naval armadas. Both Persian and Ottoman imperial battle fleets utilized the deep, enclosed bay as a strategic naval staging harbor across different centuries. In 1801, the maritime advantages of this sheltered basin brought another massive fleet to its shores when British forces gathered 200 warships here for a three-month naval landing exercise. During the Hellenistic era, Physcus was fortified with defensive stonework and developed into a major commercial port, exporting local timber, regional marble, and wine across eastern Mediterranean sea lanes to Egypt.

Modern Marmaris bears traces of turbulent seismic history. In 1957, severe earthquakes measuring 7.1 and 7.3 on the magnitude scale devastated the municipality, leveling virtually every modern building in the town while leaving only the historical castle and its immediate ancient structures standing.

Heaven Island: Nimara Cave and ancient Carian shores

On Heaven Island, located roughly five kilometres from the race course at İçmeler, sits Nimara Cave, also known on Bedir Island. Excavations conducted in 2007 revealed that human presence at the cave site stretches back approximately 12,000 years to 12,000 BC. Throughout ancient history, communities utilized the cavern as an enduring sanctuary dedicated to religious worship. Recognized for its historical and environmental value, the cave was officially designated as a protected conservation area in 1999, and its subterranean chambers continue to provide shelter for colonies of trogloxene butterflies. At the loftiest elevation of Heaven Island, stone ruins stand as physical markers of ancient occupation, including fortified city walls, a defensive watchtower, and the foundations of early residential houses.

Farther along the wider peninsula, the ancient Carian settlement of Amos preserves fortified walls, an amphitheatre, and the ruins of a classical temple within the national park territory. Near Bozukkale, the coastal stronghold of ancient Loryma guards the rocky shoreline with a well-preserved fortress featuring nine rectangular stone towers. In Taşlıca, the ancient site of Phoenix showcases intricate terrace farming systems developed to survive amidst karst topography that forced inhabitants to rely on underground water sources. About thirteen kilometres away on Losta Bay within the Bozburun Peninsula lies the ancient town of Hygassos, which formed part of the Rhodian Peraea during the Hellenistic epoch. About fifteen kilometres from the race venue, the ancient Carian settlement of Euthenae sits on the shores of the Ceramicus Sinus.

The site features an imposing walled citadel perched at the summit of a mountain ridge with defensive forts flanking both ends, while the hillside below displays the terraced ruins of the historic town. The Gulf of Gökova is a narrow hundred-kilometre arm of the Aegean Sea stretching between the Bodrum and Datça peninsulas. Guarding the seaward mouth of the gulf stands the Greek island of Kos. Along the northern coast of the gulf once flourished the urban center of ancient Ceramus, while on Sedir Island lies the ancient site of Cedrae, famous for its beach and surviving archaeological ruins. At the far eastern head of the gulf, an alluvial plain remained wild marshland until 1945. Back on the open course at İçmeler, swimmers stroke through crystal sea waters backed by thousands of years of Aegean coastal history.
