Nebelhorn was one of the first Hanoverian stallions imported into this country. Nebelhorn finished first out of 33 stallions in his 1981 performance test with scores of 8+ on his gaits and 8.67 on cross country and stadium jumping. He was selected for the State Stud at Celle and stood in Germany from 1982 to 1984. He won USDF (Hanoverian) Gold Medals at Third through Intermediaire I from 1985 to 1988. Nebelhorn also won a USDF Bronze Medal at Grand Prix in 1989 and an Individual Silver Medal at the Olympics Sports Festival in 1986. A versitile sporthorse himself, as well as a versitile producer, Nebelhorn won three hunter show championships at the Santa Barbara National in 1991.
