The Alfred G. Vanderbilt Handicap is an American Thoroughbred horse race held annually near the end of July at Saratoga Race Course in Saratoga Springs, New York. A Grade I event open to horses age three and older, it is a six furlong sprint raced on dirt.
A six year old horse can not participate in the event
According to the statement any horse over three is allowed in the event. So a six year old horse should be able to race with the best of them. This makes my statement false. I think the model might have been tripped up by the word six, or maybe how I structured my question tripped it up.
