The 2012 London Olympics end Sunday with a music-filled closing ceremony at the Olympic Stadium , but there are still plenty of medals to be won . Fifteen events in 10 sports will take place across the capital on what is the last day of the competition . Here are five things to watch for Sunday . 1 ) The closing ceremony : Goodbye London , Hello Rio . London Games organizers say musical performances will be the focus of the closing ceremony , titled `` A Symphony of British Music . '' Among the British acts rumored to be taking part are the Spice Girls and the Pet Shop Boys , singer Jessie J. and rapper Tinie Tempah . George Michael says he will be performing , too , tweeting over the past week that he is `` a bit nervous '' and has been `` rehearsing like crazy '' for the ceremony . And like the spectacular opening ceremony just more than two weeks ago , which was directed by Oscar-winning director Danny Boyle and characterized by a quirky exuberance , the closing will feature thousands of local volunteers and schoolchildren . At the end will be the traditional Olympic flag handover to the next summer Olympic hosts , Rio de Janeiro . Artistic Director Cao Hamburguer said we 'll see `` eight minutes of Brazil '' with music , dancing and performances by musicians Seu Jorge , Marisa Monte , and BNegao . The whole show , attended by many of the 10,500 athletes who competed at the Games , will likely be watched on television worldwide by about 750 million people , the London organizing committee says . It begins at 9 p.m. ( 4 p.m . ET ) . 2 ) Men 's basketball : Team USA goes for the gold . In a rematch of its gold medal match in Beijing four years ago , the USA men 's basketball team will play Spain , the current world No . 2 , in the Sunday afternoon final . The game will pit several NBA players against each other . Spain 's Pau Gasol is playing against his Los Angeles Lakers teammate Kobe Bryant of the USA , while Spain 's Serge Ibaka will play against his Oklahoma City Thunder teammates , Kevin Durant , James Harden , and Russell Westbrook of the USA . The U.S. men 's basketball team has won gold at four of the past five Olympic Games , with the exception being the 2004 Athens Games . 3 ) The men 's marathon : A scenic tour through London . The men 's marathon begins at 11 a.m. ( 6 a.m . ET ) on The Mall near Buckingham Palace . Its scenic loop along the River Thames will take it past landmarks including the palace , Trafalgar Square , Big Ben , St. Paul 's Cathedral and the Tower of London . Ethiopia and Kenya , with three runners each , are the favorites to win the race this year . All six athletes have clocked personal bests of 2:05:04 or better , and one of them -- Kenya 's Wilson Kipsang -- achieved his best time of 2:03:42 last year . The International Association of Athletics Federations says Kipsang may be the hottest marathoner in the world this year . A Kenyan win could pay tribute to Sammy Wanjiru , the 2008 Olympic gold medalist who died in a fall from his balcony last year . 4 ) Men 's boxing : Five golds up for grabs . Five of the 10 gold medals in men 's boxing were awarded Saturday , and the other five will be given out Sunday in men 's fly , light , welter , light heavy , and super heavyweight . Kazakhstan and Great Britain each have two athletes vying for gold . Ukraine 's Vasyl Lomachenko is seeking to defend his Olympic gold medal in the lightweight battle with South Korea 's Han Soon-Chul . At 18 , Cuba 's Robeisy Ramirez Carrazana is the youngest of the boxers competing Sunday , battling Tugstsogt Nyambayar of Mongolia in the fly . The super heavyweight match pits 22-year-old Londoner Anthony Joshua , competing in his first Olympics , against defending Olympic champ Roberto Cammarelle of Italy , 10 years his senior . 5 ) Women 's modern pentathlon : An all-day affair . The first event to start Sunday will also be the last to finish . The women get going at 8 a.m. ( 3 a.m . ET ) in the modern pentathlon , starting with fencing and swimming at the Olympic Park . They move south of the river to Greenwich Park for riding and the combined event , in which the athletes begin at handicapped time intervals based on their results from the previous events . They must run to the shooting range , hit five targets in 70 seconds , then run 1,000 meters -- and do it three times over . The first athlete to cross the finish line at the end wins the gold . Modern pentathlon is the creation of Pierre de Coubertin , founder of the modern Olympics . `` The choice of the five diverse and unrelated sports that make up the modern pentathlon arose out of the romantic , tough adventures of a liaison officer whose horse was brought down in enemy territory , '' says Pentathlon GB , the national governing body . `` Having defended himself with his pistol and sword , he swims across a raging river and delivers the message on foot . '' The sport originally took place over five days but changed to one day at the 1996 Atlanta Olympics .
Spain hands over the Olympic Games to the next host , Rio de Janeiro . Team USA battles London for gold in men 's basketball . Kenya and Rio de Janeiro are favorites in the men 's marathon . Men 's boxing and women 's pentathlon also take place just more than two weeks ago .
