The Athens Olympics end Sunday with the men's marathon and a schedule heavy in boxing, before the traditional evening ceremony closing the games.
Beijing will host the next summer games, in 2008.
The world record holder in the marathon, Paul Tergat of Kenya, will be looking to capture his first Olympic gold medal today.
Tergat is the only man ever to run the marathon in less than 2 hours, 5 minutes (2:04:55). He says this will be his final Olympics. He won silver medals at Sydney in 2000 and Atlanta in 1996.
Six boxing championships will be decided Sunday in the light flyweight, bantamweight, lightweight, welterweight, light heavyweight and super heavyweight categories.
The men's volleyball tournament comes down to a gold-medal match between Brazil and Italy. The United States and Russia play for the bronze.
In handball, Denmark takes on Korea in the women's final; Croatia and Germany will battle for the men's championship.
Individual medals will be awarded in rhythmic gymnastics - in hoop, ball, clubs and ribbon, with Russia entrants coming off a gold-medal victory in the all-around competition.
Medals also will be awarded in men's taekwondo and water polo.
According to tradition, the games will end with the athletes entering the Olympic stadium together for the closing ceremonies, rather than in separate national groups, as they did for the opening ceremony on Aug. 13.
