Cumano reached the pinnacle of his career with Jos Lansink at the 2006 World Equestrian Games in Aachen, where he became individual world champion after the famous Final Four. A year later, he won individual silver at the European Championships in Mannheim. He also won the Calgary Grand Prix and competed at the Olympic Games in Athens and Hong Kong. Cumano sired relatively few offspring, but their quality was outstanding. Noblesse des Tess won team bronze and finished fourth individually at the London Olympic Games, while Camille Z also competed successfully at 1.60 m level. Cumano stands for exceptional scope, carefulness and championship calibre.
