Jea de Paume is basically Squash with your hands, ouch! Roque is croquet on a hard surface, who knew? Basque Pelota is described as a game involving a bat, a ball, a basket, and a wall. This is said to be the fastest sport in the world. Tandem Cycling, perhaps would not be very exciting. And, I could pass on Rope Climbing. There are always rumors that juggling was once an Olympic sport, however, I think that it is Club Swinging most folks are referring to. This is said to be the precursor to Rhythmic Gymnastics.
And, what kind of sport is that, dancing while twirling ribbons? All I can figure is that some participants of the opening ceremonies one year lobbied to become an official sport. And, yet they discontinued athletic contests such as Basque Pelota and Rackets? Go figure.
