Vayrann
Vayrann (foaled 7 April 1978) was an Irish-bred, French-trained Thoroughbred racehorse and sire. As a three-year-old in 1981 he won four of his six races including the Prix Jean de Chaudenay, Prix du Prince d'Orange and Champion Stakes. His victory in the latter race was only confirmed at the end of a protracted and controversial process after he failed a post-race drug test. He was injured on his second appearance in 1982 and was retired to stud, where he had moderate success as a sire of winners.
