Writings indicate that the ancient Olympic Games were founded by Heracles, a son of Zeus, and the first documentation of the Olympic Games date back to 776 BC. Coroebus was the first documented Olympic champion. He won in the 210-yard run event. Coroebus ran naked in the event. The first modern-day Olympics took place in Athens in 1896, and saw 14 nations compete. The first Winter Olympics took place in 1924. In early Olympic Games competition, both the Summer and Winter Games were held every four years, and both competed in the same year, all even-numbered years. In 1994, the Olympics split, and saw the Winter Olympics compete, then the Summer Olympics compete in 1996. Each Olympic Games is now competing every four years, with a two-year offset.
