De Coubertin approved the 40-kilometer race (about 25 miles) despite the fact that few athletes alive had ever trained for -- much less competed in -- anything longer than three miles. Thus was born what one writer has called "the most audacious of races."
In 1908, the course began at Windsor Castle and ended 26 miles later at the stadium. Once inside, runners had to complete a partial lap, measured at 385 yards, so as to finish in front of the royal box. (In 1924, the odd and random distance of 26 miles 385 yards became the marathon standard.)
The favorite was Canada's Tom Longboat, an Onondaga Indian who had captured the 1907 Boston Marathon in record time. The U.S. entered seven runners, including a slight Irish American lad named Johnny Hayes. Italy's Dorando Pietri went unheralded; many reporters believed that Pietri was his first name.
Tens of thousands of spectators lined London's roads to cheer on the 55 runners (from 16 nations) sweltering in the afternoon heat. Longboat held the lead at the 17-mile mark, when he suddenly dropped out. Unconfirmed reports indicated that he had ingested strychnine, the performance-enhancer of choice during this era.
Wearing red pantaloons that reached his knees and a white kerchief to shield his dust-covered hair, Pietri took control at the 25-mile mark. But he had reached the edge of human endurance; he collapsed repeatedly, only to be aided to his feet. "He was helped by the officials," says Olympic historian Bill Mallon, "in clear violation of the rules."
A groundbreaking photograph captured Pietri's desperate last effort at the finish, supported by two attendants (one of whom was falsely identified as Sir Arthur Conan Doyle, the creator of Sherlock Holmes). Medical staff carried away Pietri as the Italian flag was hoisted. Meanwhile, Hayes entered the stadium and completed his lap.
The U.S. team lodged a protest. Pietri was disqualified and Hayes awarded the gold medal. Hayes' victory was the last for a U.S. Olympic marathoner until Frank Shorter broke through in 1972.
Hayes was the champ, but Pietri was the hero. The next day, after he was released from the hospital, Queen Alexandra presented him with a silver cup. Photographs of the race's conclusion -- among the first sports-action images ever produced -- appeared in newspapers around the world.
