The first test (prova) occurred at 7:15pm on Saturday evening. The maximum amount of time any the jockey has had with the horse is about 6 hours. This is the first time they are with the horse on the Palio course.
The crowds are amazing! We stood in the center of the Piazza del Campo so it was difficult to get good photos of the race, especially as the horses outrun my camera’s shutter speed (I’ll need to upgrade to a newer camera!).
