After all the discussions about crime, poverty, pollution, corruption and the Zika virus, it’s now time to shift our attention to the actual games at the 2016 Summer Olympics in Rio de Janeiro.

More than 11,000 athletes representing more than 200 countries will compete in 42 Olympic sports beginning Friday. In total, there will be 306 events over the course of 19 days between the opening and closing ceremonies.

The number of black athletes from around the globe in the Summer Olympics always dwarfs the number in the Winter Olympics (something about cold weather, snow and ice?), and this year is no exception. When national anthems are played and the winners step onto the medal stand, here are some folks you might see.

Nicola Adams, Great Britain, Boxing

Adams, a flyweight, became the first woman to win an Olympic boxing gold medal when she schooled Chinese great Cancan Ren at the 2012 London Games. Adams is England’s four-time national champ.

Mutaz Barshim, Qatar, High Jump

Barshim won bronze in 2012 but has a taste for gold in Rio. He was dealing with a stress fracture four years ago in London and didn’t receive the green light to compete until 10 days before the Olympics began.

The biggest prize on the free-agent market this summer, Durant is getting used to playing with new NBA teammates Klay Thompson and Draymond Green. He won gold at the 2012 Olympics and was named MVP of the 2010 world championship squad.

The reigning Olympic and world champion broke his world record during the 2015 outdoor season. He’s looking to become the first back-to-back Olympic champion in the decathlon since Britain’s Daley Thompson in 1980 and 1984.

An ankle injury last month killed Felix’s dream of winning gold medals in the 200- and 400-meter when she failed to qualify for the former. But the six-time medalist is a favorite to win the latter (and perhaps with the relay teams).

Shelly-Ann Fraser-Pryce, Jamaica, 100 Meters

Nicknamed “Pocket Rocket” because of her 5-foot height and explosiveness, Fraser-Pryce in 2008 became the first Jamaican woman to win Olympic gold in the 100. In London she became only the third woman to successfully defend the 100-meter title.

Ghirmay Ghebreslassie, Eritrea, Marathon

He was the youngest man, at 19, to win the marathon at the World Championships when he prevailed on a sweltering day in August 2015 as the favored Kenyans struggled with the heat. It was Ghebreslassie’s first career win.

At a meet in May, the Kenyan-born athlete became just the second woman to crack the nine-minute mark, running 8:59.97 to miss the world record by 1.16 seconds. She is among a flow of talented Kenyans who have been recruited by oil-rich Bahrain.

Winner of six of the last seven marathons he has run, Kipchoge missed the world record by 8 seconds in the 2016 London Marathon. His time of 2:03:05 was the third-fastest in marathon history and second-fastest on a record-eligible course.

Simone Biles, U.S., Gymnastics

Biles is a favorite to win gold in the all-around, floor exercise, vault. The 4-foot-8 teenager owns the most world medals in U.S. history, with 14, and the most world championship gold medals of any female gymnast, with 10.

Manrique Larduet, Cuba, Gymnastics

The star of his country’s gymnastics team, Larduet is strongest at floor exercise and the horizontal bar. He will be Cuba’s first gymnast at an Olympics since 2004, now that an anti-defection policy has been eased. 

Simone Manuel, U.S., Swimming

After winning the 400-meter gold at the 2008 Olympics, Merritt was forced to withdraw from the 2012 Olympics because of a hamstring injury. Now the 30-year-old elder statesman is looking for gold in the 200 and 400.

Long-distance runners Yiech Pur Biel, James Nyang Chiengjiek, Anjelina Nadai Lohalith, Rose Nathike Lokonyen and Paulo Amotun Lokoro will compete as part of the Olympics’ first-ever Refugee Team. Record-breaking Nigerian long-distance runner and peace activist Tegla Loroupe “discovered” these five runners when she organized a foot race two years ago outside a South Sudan camp for nearly 200,000 Africans displaced by violence and famine. These five runners make up half of the Olympics’ Refugee Team.

The most decorated sprinter of all time, Bolt has won the 100-, 200- and 4-x-100 meter relay in each of the last two Summer Olympics. An injury at the Olympic trials may have the “world’s fastest man” missing a step, but either way, Bolt says Rio will be his last Olympics.

Yulimar Rojas, Venezuela, Triple Jump

Semenya is one of the Olympics’ most compelling figures, an athlete with intersex conditions—not conforming to standard definitions of male or female—who once was sidelined for 11 months. She won a silver medal at the 2012 Olympics and is a heavy favorite for gold in Rio.

Shields’ gold medal at the 2012 Olympics—when women’s boxing made its debut—was the first by a U.S. boxer since 2004. She was a high school junior fighting women nearly twice her age. Now she’s among the biggest favorites on the Team USA delegation.

Yego wasn’t fast as a child in Kenya, home to some of the world’s best distance runners. So with the help of YouTube videos, he taught himself to throw the javelin and became a world champion. He’s the first Kenyan to win a world title in a field event.

Tony Yoka, France, Boxing

The superheavyweight is described by Sports Illustrated as “fast of hand and foot and moves in the ring more like a heavyweight." Yoka won a gold medal at the World Championships and has every reason to expect the same result in Rio.
