Rubio was an American thoroughbred racehorse best remembered as the winner of the 1908 Grand National steeplechase run at Aintree, England.
The horse was bred in Rancho del Paso stud in California in 1898[1] by La Toquera and Star Ruby from the damsire Sir Modred by breeder James Ben Ali Haggin.
As a five-year-old, the horse had broken down so severely that he was put to pulling a trolley bus [2] in Towcester to regain the strength in his legs.
Rubio defeated his better-fancied stable companion, Mattie McGregor, by 10 lengths for trainer William Costello.
When he returned to the stables, he was found to have again broken down and was promptly retired from racing.
