Calvaro Z enjoyed an impressive international career with Jos Lansink and later with John and Michael Whitaker. He won team silver at the European Championships in Mannheim, finished ninth individually at the World Equestrian Games in Rome and competed at the Olympic Games in Sydney. Calvaro Z also made a significant impact as a sire. Katchina Mail won team silver with Patrice Delaveau at the World Equestrian Games, while Night Train, Ralvesther, Calvilot, Callas Sitte Z and Boyfriend du Seigneur also competed internationally at 1.60 m level. This imposing son of Caletto I out of a Capitol I dam passed on a powerful canter, exceptional scope, carefulness and courage.
