At the age of two, she started eight times and lost once. For this, she was named the
American Champion Two-Year-Old Filly of 1963. This was before the
Eclipse Awards when championships were determined by the
Daily Racing Form,
Turf and Sports Digest magazine, and the Thoroughbred Racing Association. Tosmah was named champion by
Daily Racing Form and
Turf and Sports Digest, while
Castle Forbes took the rival Thoroughbred Racing Association award. When Tosmah was three, she started in fourteen races, winning ten, vying all year with a splendid filly called
Old Hat. 1964 saw her highest earnings, $305,283, and the title of
American Champion Three-Year-Old Filly. She was named
American Champion Female Handicap Horse by
Daily Racing Form. In 1965, at the age of four she won her second
Maskette Handicap (now known as the
Go For Wand Handicap) under 128 pounds, in the process beating the great filly
Affectionately, no. 81 in the
Blood-Horse magazine List of the Top 100 U.S. Racehorses of the 20th Century, in a driving finish. In her final season, Tosmah defeated
Lucky Debonair, the winner of the 1965
Kentucky Derby, in the John B. Campbell Handicap. ==Broodmare==
