Plenty has changed in the 45 years since the legendary John Henry nipped The Bart in the first and most memorable edition of the Arlington Million. Surviving numerous obstacles, the 1 1/4-mile race remains one of the most prestigious events run on American turf.

Memories of Arlington International Racecourse will be revived on Saturday when the famed racetrack’s premier turf stakes will be contested at Colonial Downs. For fillies and mares, there’s the Beverly D. Stakes, which is named for longtime Arlington owner Richard Duchossois’s wife, Beverly. As usual some of the year’s top turf females will be on hand for another competitive renewal of the 1 3/16-mile stakes.
