The One Hour Classic is Circolo Surf Torbole's most iconic regatta, first organised in 1989. The winner is the windsurfer who manages to sail cross the lake in one direction between the Conca d'Oro and the Casa della Trota the most times in one hour. From 2018, participation is open to both the Fin and Foil categories. Since 2023, the record in both specialities belongs to home champion Bruno Martini.
