Breeders Crown Open Mare Trot

The Breeders Crown Open Mare Trot is a harness racing event for three-year-old and older Standardbred mare trotters. It is one part of the Breeders Crown annual series of twelve races for both Standardbred trotters and pacers. First run in 1986, it is contested over a distance of one mile. Race organizers have awarded the event to various racetracks across North America.

Historical race events
In 1989, Grades Singing won a record third Open Mare Trot. An international trotting star in top level races, in 1987 she won Sweden's Olympiatravet, Finland's Finlandia-Ajo, and Italy's Gran Premio Lotteria. The following year she returned to Europe where she claimed victory for a second time in Italy's 1988 Gran Premio Lotteria plus that country's Gran Premio delle Nazioni.

In 1990, Peace Corps won her first of two Open Mare Trots, doing it in World Record time. Her 1992 win in the Open Mare Trot made her the only horse in history to win four Breeders Crown races.

From 1996 through 2003 the Open Mare Trot was not run and female horses were left to compete against their male counterparts in the Breeders Crown Open Trot.

Five horses have won the race twice: Peace Corps (1990, 1992), Mystical Sunshine (2006, 2007), Buck I St. Pat (2009, 2010), Emoticon Hanover (2017, 2018), and Manchego (2019, 2020).
