  • 2016 Longines Masters' Season II : We Ride The World

    "If equestrian sports are a matter of taste, there is still a consensus that no one can question: the beauty of the horse transcends the sport, and beyond the extraordinary performance of the riders, conveys a feeling of wonder.
    And this is doubtlessly what makes show jumping universal, transcending countries, cultures and populations. Its treasured values do not need rules to exist. They are shared without effort as a testimonial. There is something profoundly captivating in the competition, like a theatrical play that mesmerizes and transports you.
    In a world that is becoming more and more digital, the experience of the live spectacle is a rare and enviable commodity. All over the world sports events gather the crowds and unlock passions, inspired by social networks as symbols of a generation that is eager to share.
    This emotion, this dream, this enchantment that we bring to our «Masters » is our mission at EEM. Each new season of the Longines Masters Series, "Grand Slam Indoor of Show Jumping," across three continents, three cultures, three emblematic cities, Los Angeles, Paris, and Hong Kong, we carry the values of our sport as an antidote to the venoms of our time. A few moments of wonderment in a tormented world."
