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 Mordred by breeder, James Ben Ali Haggin and was sent to the United Kingdom as a yearling, having been purchased for 15 guineas.
As a five year old the horse had broken down so badly that he was put to pulling a trolley bus in Towcester to regain the strength in his legs. The regime worked and after two years the horse was put back into training.
At the 1908 Grand National the horse was relatively unconsidered and wassent off at 66/1, ridden by Henry Bletsoe, the son of the horse's former trainer Bernard Bletsoe, going on to defeat his better fancied stable companion Mattie McGregor by 10 lengths for trainer Frederick Withington.
Rubio returned in 1909, falling at the water jump. When he returned to the stables he was found to have again broken down and was promptly retired from racing.
