The heart of Portugal is one of the regions with the greatest historical and natural heritage and the least explored in Portugal. Since 2017 we have fallen in love with the magical corners of the Castelo de Bode Dam and its unique characteristics for the practice of this sport. That is why we always look forward to returning to the magic of this place.

For this 2023 edition and the National Swimrun Championship, the race course route has been reformulated and once more we will follow the undulating contours of GRZ (Grande Rota do Zêzere) on challenging trails, surrounding the areas of the village of Fontes and do Souto with its incredible breathtaking views over the Castelo de Bode Dam. The finish line will be as in previous years at the Fluvial Beach of Aldeia do Mato.

The warm temperatures in the end summer period are perfect for swimming with water temperatures between 20 and 23 degrees and about 28 degrees in the air. When exposed to the sun, temperatures can become quite hot, so on this demanding route, participants will have to think about their effort management along the route. The dam's fresh water provides less buoyancy, adding an added safety factor as it is a dam.
