About the race

The approach to the start line in Porto Belo is marked by the winding coastal roads that reveal the Emerald Coast, a transition from the inland plateau to a maritime landscape shaped by centuries of history. As you arrive at the beach on the left side of the tourist pier, the view is dominated by the blue expanse that historically welcomed the Azorean settlers who established the Vila de Nova Ericeira in 1817. This heritage remains embedded in the local rhythm, grounding the 100km relay challenge in a narrative of survival and adaptation that feels tangible when you step into the water.

The marine environment

Swimming along this coastline requires an understanding of the aquatic boundaries that define the route. As you transition toward Bombinhas, known since 2013 as the 'Capital of Ecological Diving', the clarity of the water becomes a functional reality for navigating the rocky headlands. The course passes through areas protected by the Arvoredo Biological Marine Reserve, where strict environmental preservation creates a controlled, pristine habitat. You will encounter the steep, rugged geography of the peninsula, where the transition from shallow, sandy bottoms to deep escarpments demands constant focus. The interaction with this environment is facilitated by a support sailboat, providing a mobile base as you progress toward Florianópolis. If you seek shorter distances to test these conditions, the Bombinhas Summer Crossing offers a focused look at the same coastal currents in January.

Race day mechanics

This 100km relay is structured for five-athlete teams, with swimming limited to daylight hours and rest periods aboard the support vessel. The use of wetsuits is permitted, a necessary consideration given the water temperatures that fluctuate significantly throughout the year—ranging from 23°C in late April to as high as 31°C in early March. Because the event relies on maritime logistics, including a high-speed support boat and an onboard lifeguard, the itinerary remains subject to real-time adjustments based on wind and swell. Every kilometer completed is tracked via GPS, ensuring the integrity of the performance as you navigate between the coastal points. The journey concludes back in Porto Belo, where the local marine museums, such as the House of the Man of the Sea, offer a final perspective on the deep-rooted relationship between the local population and the ocean currents you have just traversed.

Things to do nearby

Beyond the race, the region serves as a hub for ecological and maritime activities. Swimmers can explore the coastal biodiversity through guided snorkeling tours in the protected coves of Bombinhas or participate in kayaking excursions along the rocky headlands. For those interested in local heritage, the Marine Aquarium Museum provides a detailed look at the regional ecosystem, while the surrounding trails in the restinga vegetation offer a quiet retreat after the event.
