The Hartwig Memorial Trophy is awarded annual to the "Best North American-Bred Young Mare." This award is to reward the young mare that has the best-combined scores from her Studbook Inspection and her Mare Performance Test.
The Hartwig Memorial Trophy is restricted to mares that are three- and four-years-old in a calendar year. The goal is to reward those mares that are performance tested when they are young, and show good innate athletic ability and talent.
