The various Masters Grand Slam legs open their magnificent rings to riders who are less accustomed to such grandeur. In the Invitational, young and amateur riders can compete on the same sand, over the same obstacles, in the same conditions, on the courses built by the same course designer as the best riders in the world! The courses are between 1.15m to 1.30m in height, making it a suitable setting for these riders to make progress, often accompanied by their trainers, some of whom perform in the Longines Masters classes.
