Traversata a nuoto del Lago di Iseo

Halfway through the distance, you find yourself suspended over the deepest point of the basin, scanning the horizon where the Monte Isola massif rises abruptly from the depths. To your left, the neogothic towers of the Loreto island castle catch the sunlight, a curious structure commissioned by a former Royal Navy captain who transformed a quiet retreat into a fortress-like landmark. Looking upward, the silhouette of the Madonna della Ceriola Sanctuary marks the island's summit, a site of devotion established half a millennium ago that serves as your primary navigational beacon during the final leg of the swim.

Historical currents and legends

As you approach the western shore, you glide over the submerged history of the Brescian territory. This was once a strategic defensive line for the Oldofredi family, who erected strongholds to secure their dominion over these waters. The shoreline carries the legacy of royal visitors like Queen Caterina Cornaro, who sought refuge within the walls of the fortress of Martinengo. Even the air around the lake villages feels steeped in narrative, particularly during the years when the Santa Croce di Carzano festival transforms the waterfront, a tradition born from the memory of an ancient epidemic and a local legend of healing that has persisted for generations.

Race day logistics

The Traversata a nuoto del Lago di Iseo, scheduled for August 30, 2026, requires a measured approach to your pacing. With a 3000m course stretching from the Chiesa San Rocco in Predore to Lungolago Marconi, the event is strictly regulated to ensure safety, with a 90-minute limit that necessitates a consistent stroke. The 48-58 EUR registration fee supports the logistics of a point-to-point crossing, including the ferry transfer to the start, water-based support from dedicated 'Angels', and a numbered buoy that you must wear throughout the effort. Unlike the shorter, more intimate Lago d'Endine, this crossing demands a clear focus on the channel markers as you navigate toward the Iseo shoreline. If you enjoyed this stretch, you might consider the technical challenges found in the nearby Giro Isola Loreto, which offers a different perspective on the castle you pass today. The lake level remains stable thanks to the Sarnico Dam, ensuring a predictable surface for your arrival at the designated boat channel.
