In the spotlight, it’s time for many Olympians to shine on the world stage

The London Olympics promises theater as riveting as anything on stage in the West End, and some of the athletes in leading roles are familiar names.

David Beckham, the British soccer icon with the GQ looks, has been front and center since Great Britain submitted its bid to host the 2012 Summer Games. Although he was left off Great Britain’s Olympic team, expect to see him everywhere.

Usain Bolt, the aptly-named Jamaican sprinter, is back for an encore after his show-stopping performance in Beijing four years ago — gold medals and world records in the 100 meters, 200 meters and sprint relay.

In his way could be countryman and world champion Yohan Blake, American Tyson Gay and Frenchman Christophe LeMaitre, who shrugs off questions of race but is best known for being the first white man to break the 10-second barrier in the 100 meters.

Tennis stars Serena Williams, Novak Djokovic, Roger Federer and Andy Murray (injured Rafael Nadal withdrew), fresh off Wimbledon, will ditch their whites and return to the hallowed grass of the All England Club in their national colors to battle for Olympic gold.

And soccer player Neymar (no last name necessary) will try to lead Brazil to the only major title it has yet to win. In three seasons, the 20-year-old has scored nearly 100 goals for Santos (Pelé’s former club), and Pelé considers him better than Argentine star Lionel Messi.

More than 10,000 athletes from 200 countries will compete in 36 Olympic sports. Most are not famous, but every one of them has a story.

Here are 10 to keep an eye on:

Jessica Ennis, track and field, Great Britain:

The Games have yet to begin and already the photogenic Ennis, 26, has endorsements with Jaguar, Aviva, Olay, adidas, Powerade, Omega and BP. She is pulling in more than $1.5 million a year, making her the highest-paid female athlete in England.

Ennis’ father was born in Jamaica, and her mother was born in England. He is a painter and decorator; she is a social worker.

Neither excelled at sport, but they signed their 11-year-old daughter up at a track club in their hometown of Sheffield, and she proved to be talented at most disciplines.

Ennis won the world heptathlon titles in 2009 and 2010 and was poised to medal at the Beijing Olympics in 2008. A stress fracture in her right foot kept her home. In the past year, she settled for a silver medal at the 2011 world championships behind Russian Tatyana Chernova and silver at the 2012 indoor world championships behind Nataliya Dobrynska of Ukraine.

Oscar Pistorius, track and field, South Africa: Bolt might be the most phenomenal track athlete at these Olympics, but the most inspirational is Pistorius, a double amputee from South Africa who will make history by becoming the first amputee runner to compete in the able-bodied Olympics.

Pistorius runs on carbon-fiber blades and is known as “The Blade Runner.” He has clocked an Olympic qualifying time of 45.30 seconds in the 400 meters and was selected by the South African Olympic committee for the individual event and the 1,600-meter relay team. He also has plans to compete in the Paralympics.

Born without fibulas in either leg, Pistorius had both legs amputated below the knee when he was 11 months old. His disability didn’t keep him from competing in rugby, water polo and tennis in school. As he got older, he focused on running.

Pistorius’ remarkable success in able-bodied races has not come without controversy. Some competitors feel the artificial limbs give him an unfair advantage, and the international track federation ruled as such before the 2008 Beijing Olympics. Pistorius challenged the ruling, and it was overturned later that year by the Court of Arbitration for Sport.

Although he was eligible for the 2008 Olympics, he fell short of the qualifying standard. He won gold medals in the 100, 200 and 400 meters at the Paralympics that summer.

Hiroshi Hoketsu, equestrian, Japan:

Hoketsu qualified for the individual dressage, riding a 15-year-old horse named Whisper. He first competed in the 1964 Games when he was 23. He was 67 when he finished ninth in the team event and 35th as an individual at the Beijing Olympics four years ago. Back home in Japan, they call him “The Hope of Old Men.”

He has an endorsement deal with a health food chain and continues to train twice a day.

Believe it or not, Hoketsu is not the oldest Olympian in history. Swedish shooter Oscar Swahn was 72 when he won a silver medal at the 1920 Olympics in Antwerp.

Aliya Mustafina, gymnastics, Russia, and Larisa Iordache, gymnastics, Romania:

Mustafina won the 2010 all-around world championship at age 15 and was favored to win the 2001 European championship. But she tore the ACL of her left knee on the landing of a difficult vault and was carried off the podium, reminiscent of the Kerri Strug vault injury at the 1996 Atlanta Olympics.

She had surgery and did not compete for eight months. She started training again in December 2011, and though she has struggled in her first few meets, she is considered one of the favorites.

Also watch for Iordache, 15, who has drawn comparisons to Nadia Comaneci, the tiny Romanian who won the 1976 gold. Iordache won the gold in floor exercise and silver in beam at the recent world championships.

Chris Hoy, track cycling, Great Britain:

The Scottish track cyclist won three gold medals in Beijing and was knighted Sir Chris by Queen Elizabeth II in 2009. He is on pace to become Great Britain’s most successful Olympian, as he has collected four golds and a silver. Rowing legend Steve Redgrave holds the national record with five golds and a bronze. Hoy is the first Briton to win three gold medals in a single Olympics since freestyle swimmer Henry Taylor in 1908.

Caster Semenya, track and field, South Africa: Doubts about her gender made life miserable for South African runner Semenya three years ago, but she said she has put it behind her and if she wins a medal, she will dedicate it to Nelson Mandela, who helped her during her tough times.

When Semenya, 19, won the 800-meter world title in 2009, skeptics insisted she was not a woman, and she was forced to undergo testing.

It turned out she did have excessive male genes because of a medical condition, but the international track federation cleared her to compete as a woman.

She won the silver medal at the 2011 world championships and is now coached by Mozambique legend Maria Mutola.

“Life wasn’t easy, but I kept dealing with the situation with help from my family, friends and management,” Semenya said. “[The gender question] is not in my mind anymore.

“For me it’s in the past. I have to focus on the future, and that’s what I’m doing right now.”

Kohei Uchimura, gymnastics, Japan:

Uchimura won the silver at the 2008 Games, and now that China’s Yang Wei has retired, the door is open for the Japanese gymnast to win it all.

Ranomi Kromowidjojo, swimming, Netherlands:

Her name might be new to casual fans, but swimming enthusiasts have known about her for years. She has been competing at the elite level since age 15, swam in her first world championship at 17, and at 18 won an Olympic gold medal in Beijing with the Dutch 400-meter relay team.

Her training was interrupted last year by a bout of meningitis, but she is healthy now, and the natatorium announcer ought to start practicing her name.

Lin Dan, badminton, China:

He is one of the most recognizable athletes in China and a favorite of the paparazzi, especially because he is married to Xie Xingfang, China’s No. 1 women’s badminton player.

The Olympic badminton competition will be held at Wembley Arena, and Lin is favored to win gold again. Let the Lin-sanity references begin.
