Most Gr 1 wins by a female against males

[Calzone Lord]

Imp's win in the 1899 Suburban Handicap in track record time was probably the first truly great performance where a female scored against males.

Imp made 50 starts in her 3-year-old season -- and more amazingly, she did it over a span of just 7.5 months because her first race was on April 1st and her last on November 15th.

The year she won the Suburban was her five-year-old season...and the Suburban was in a stretch where she raced 21 times in a span of 86 days. Basically, she ran once every four days for almost three full months.

On four different occasions during her career -- Imp raced on back-to-back days. She made 171 starts and raced till the age of 7.
