The gang is selling lemonade and hot dogs across the street from the big racetrack, where Sammy and Farina's father is a jockey, but since Mary's father owns a horse, she can let the rest of the gang in for free. The kids have so much fun at the track that they decide to mastermind their own races with anything they can find to ride, which turns out to be such noble steeds as a mule, a cow, a horse, two dogs, and a goat. Nothing is overlooked in their kiddie race from the brass band to the betting window (odds up to 1000 to 1). Mary's father even offers a five dollar purse to the winner. The only thing they miss is the willingness of their pets to be ridden, and the race turns into a marathon run with Farina leading the way on his tricycle and winning! Unfortunately, the police come to break up the play, and everyone now has something to be running from instead of toward.
