A big change is coming to horse racing's Triple Crown, with the Preakness Stakes moving to three weeks and a day after the Kentucky Derby and being run on Sunday for the first time. No Triple Crown race has ever taken place on a Sunday in the century-plus-old history of the series. Except for 2020 during the pandemic, the Preakness has been on the third Saturday in May, two weeks after the Kentucky Derby, since 1950. The aim is to get more Derby horses to participate in the second leg of the Triple Crown. "The idea of doing it Saturday-Sunday, quite honestly, was to create a weekend celebration and not just have it be a one-day event in the middle of a Triple Crown series."
