The world’s top athletes will be fighting for medals in London on Monday as the top two finishers in the 200-meter and 4×100-meter freestyle will be separated by a hair.
They will battle for the gold medal in the 4x200m relay, which was won by Usain Bolt and Usain Mir by two lengths.
The defending champions will also be fighting to be the first to clinch the bronze medal in freestyle as well as the first since 1996.
The last time these two men won a gold medal together was in the 1992 London Olympics, when Bolt won the gold with Mir winning bronze in the 100.
The London Games will be the final race before the Winter Games begin in February, and Bolt and Mir will meet for the first time in the finals in February.
Bolt won silver in the men’s 200 meters at the 1992 Tokyo Olympics, but he didn’t win a medal in either event in London.
His silver came at the 1996 Tokyo Olympics in the final.
Mir won bronze in his 100m freestyle relay at the 2002 Sydney Olympics, and won gold in the women’s 200m freestreak at the 2003 London Games.
Both men have had injuries over the years, including an ACL tear in 2009 and a torn ACL in 2016.
“I am very disappointed to lose the gold in London,” Bolt said in a statement.
“We are very close to clinching the silver medal in Beijing and I have been working hard to get back to the podium in London.”
The women’s 4x400m relay team will be split between Bolt and Rio de Janeiro’s Fabio Aru.
Bolt, who was part of the team that won gold at the 2008 London Olympics in which he was injured, said the decision was “difficult” but that he “will never give up.”
“The team has worked so hard to win gold at London,” he said.
“It’s an amazing feeling to have an opportunity to do so.
I am still very much looking forward to Rio.”
Mir, who won gold with Bolt at the 2012 London Olympics and 2012 Tokyo Olympics and won bronze with Bolt in the 2000 and 2004 Beijing Olympics, said he will miss London and the Olympics.
“I will miss all the great events, the great athletes, the support from my teammates, the incredible support from the fans and all the support I have received from all the people who have been there with me throughout this journey,” he wrote in a Facebook post.
“There is no greater feeling than winning gold.”
Bolas silver and a gold in Beijing are the most ever achieved by an African runner, but the rest of the world has had its share of athletes go out on top in recent years.
Bolt has won two golds in London and a silver in Beijing.
Brazil’s Ana Silva, a two-time gold medalist in the 400m and 200m in London, won gold on Sunday in her second world title.
World records in the field of 400m at the 2014 Games in Rio de Janiero were set by South Africa’s Sarah Tewksbury and China’s Guo Shuai.
The South African won the race in 1:01.54.
In the 200 meters, a bronze medalist from Brazil’s Natal province won gold.
A bronze in Rio was the first medal for the world since 1996, when Kenya’s Tymeka Nkomo took gold in 1.05.45.
Another bronze medal was earned by South Korea’s Jae-yong Kim in the 10,000 meters, with a time of 1:05.88.
Nkomo finished second in her final event, the 100m hurdles, behind a Russian woman, but she will not be competing in Rio.
Tewksborough, the Olympic bronze medallist in London in 1988, is still competing in the Olympics in London but is not competing in any of the Olympic track events, including the men.
She is competing in her seventh Olympics, which she won in 2000, the most in any single event in Olympic history.
She has won three Olympic titles in the past 10 years.
Kim, who has also won four gold medals in the events, will be competing for the second time in Rio in her fourth Olympics.
A few of the other athletes who will be vying for gold in Rio include Jamaican sprinter and 800m champion Usain Shah, who will also compete in the relay and the 200m, the 400 meters and the 1,500 meters.
South African sprinter, world record holder and world record-holder Meb Keflezighi will also make his fourth appearance in the Olympic Games.
