|TRA American Champion Older Male Horse|
Leading sire in North America (1981)
Nodouble (1965–1990) was an American Thoroughbred racehorse and sire. In a career that lasted from 1967 to 1970, he won eleven races and was twice voted American Champion Older Male Horse by the Thoroughbred Racing Association.
Bred by oilman Gene Goff’s Verna Lea Farms in Fayetteville, Arkansas, he was out of the mare Abla-Jay. Damsire Double Jay was the 1946 American Champion Two-Year-Old Colt and a four-time Leading broodmare sire in North America. Nodouble's Australian-bred sire, Noholme, was the 1959 Australian Horse of the Year who took nearly a full second off the race record in winning the prestigious Cox Plate. Noholme was purchased in July 1960 by Gene Goff and brought to the United States where he raced until being retired to stud. Nodouble was trained by Bert Sonnier.
At age two, Nodouble was competitive in stakes races for his age group but did not record a significant win. As a three-year-old, he began to blossom into a consistently good runner. Nodouble had not been nominated for the 1968 U.S. Triple Crown series, but after he won the Arkansas Derby  owner Goff paid a supplementary fee to enter the colt in the second leg, the Preakness Stakes. Nodouble finished third behind winner Forward Pass and went on that year to win the first of two straight editions of the Hawthorne Gold Cup Handicap and to defeat the great Damascus in the Michigan Mile And One-Eighth Handicap.
Racing at ages four and five, Nodouble was named American Champion Older Male Horse by the Thoroughbred Racing Association in both years. The rival Daily Racing Form award went to Arts and Letters in 1969 and Fort Marcy in 1970. His major wins included the richest race in California, the 1969 Santa Anita Handicap, after earlier winning the Strub Stakes but being disqualified to second place. In addition, he ran second to Arts and Letters in the 1969 Woodward Stakes, Jockey Club Gold Cup and Metropolitan Handicap. Racing in California in 1970, Nodouble won the San Pasqual Handicap. In New York, he won the 1970 Brooklyn and Metropolitan Handicaps.
At the end of October 1970, Gene Goff retired Nodouble. In 1971, he began his first year at stud in California. After initially being unsuccessful both there and in Kentucky, Nodouble was moved to Florida to stand. He met immediate success while standing at Lasater Farm in Ocala, and by 1981 his progeny made him that year's Leading sire in North America. Some of Nodouble's prominent offspring includes:
- Double Discount (b. 1973) - set world record for 1¼ miles on turf
- No Class (b. 1974) - Canadian Horse Racing Hall of Fame, dam of eight foals of which seven raced. She produced six stakes winners, including four Canadian Champions
- Overskate (b. 1975) - Canadian Horse Racing Hall of Fame inductee who was voted a record nine Sovereign Awards
- Mairzy Doates (b. 1975) - filly who won Matchmaker Handicap (1981), New York Handicap (1981), Japan Cup (1981)
Nodouble died in 1990 having sired 91 stakes race winners and was the broodmare sire of 89 stakes race winners.
