 These races are based on those of the same name in the United Kingdom, run at Newmarket in the first weekend in May.Both races have quickly established themselves on the New Zealand calendar, and the 1000 Guineas routinely attracts all of the country's leading fillies and, as a crucial race in the Filly Of The Year series, is regularly taken out by the eventual winner of that title.Among the best recent winners are Katie Lee, Seachange, King's Rose, the brilliant but ill-fated Taatletail and Tycoon Lil.
