Aldeia do Mato Open Water Swimming 2026

About the race

The Aldeia do Mato Open Water Swimming event, famously known as the 'Grande Descida de Castelo de Bode', is much more than a race; it is a pilgrimage for those who love the water. Set within the breathtaking landscape of the Castelo de Bode reservoir in central Portugal, this multi-stage competition invites swimmers to traverse the pristine, winding waters of the Zêzere River. Surrounded by lush, rolling hills and hidden river beaches, the venue provides a serene yet challenging environment that feels miles away from the bustle of modern life.

Now in its 5th edition, the event has cultivated a passionate community, attracting swimmers of all levels from across Portugal and beyond. Whether you are aiming for the full, grueling 50 km circuit or opting to test your mettle in a single, exhilarating stage, the atmosphere is electric. The race is organized by the dedicated team at Clube Swim4fun, who pride themselves on a format that balances professional competition with a deep respect for the natural environment. The camaraderie among participants—who often travel with their own support kayakers—creates a unique, festival-like spirit that defines the weekend.

This is an exceptionally inclusive event that welcomes swimmers aged 14 and above, fostering a supportive environment where athletes are cheered on by locals and fellow competitors alike. The event is a perfect choice for those who want to combine a serious physical challenge with a getaway in the heart of the Santarém region.
