About the race

The water here is still, sheltered from the raw power of the Indian Ocean that churns just a few kilometers away. As you settle into your rhythm, the residential quays of Marina Martinique flank your path, a stark contrast to the rugged coastline that historically supported a small fishing village in the 1850s. This is the heart of the Kool-a-Sun Marina Mile, an annual gathering held every December 30th that strips away the unpredictability of the open sea while maintaining the discipline of a 1600-meter race.

A landscape of currents and history

While the marina offers a contained environment, the surrounding Eastern Cape is defined by the shifting dynamics of the Kabeljous and Seekoei estuaries. These waterways, rich in biodiversity, serve as a sanctuary for over 120 bird species, including the red-knobbed coot. The sense of place here is rooted in the legacy of J.A. Jeffrey, who established the first trading store in 1849, long before the area became a global focal point for wave-riders. You are swimming in an area that transformed from those quiet colonial foundations to the epicenter of the surfing world, a shift accelerated by the 1966 film *The Endless Summer*.

Navigating the local lore

Swimmers at this venue often reflect on the proximity to the coast’s more volatile sections, specifically the Supertubes surf break. The legendary status of these waves—stretching over 300 meters—is intertwined with the local maritime narrative, including the 2015 incident where professional surfer Mick Fanning survived a shark encounter nearby. While the marina’s internal layout keeps your focus on the buoys and your stroke mechanics, the geographic closeness to those famous point breaks and the Seekoei River Nature Reserve adds a layer of intensity to the experience. The event remains a staple for those seeking a controlled, technical course before the year concludes.
