A total of 23 athletes at the first Youth Olympics in Singapore in 2010 went on win Olympic medals in 2012. Perhaps the most memorable was South African swimmer Chad le Clos, who beat Michael Phelps in the 200m butterfly.
Le Clos, now 22, was far more successful at the Youth Olympics, where he won five medals, including silver in the 200m fly.
“It taught me a lot of lessons that I wouldn’t have learned,” le Clos said. “A lot of people told me when I was younger that I wasn’t going to be a great butterfly swimmer. I shouldn’t even try to compete. Look at me a couple years later.”
Le Clos is in Nanjing, China, as an athlete ambassador this time around.
“To think that I’m an inspiration to young kids out there is a blessing,” he said. “I know what it feels like. I was one of those kids who looked up to many people.”
Le Clos relives his victory over Phelps in the above clip, but he did not go up against Phelps at the Pan Pacific Championships last week. South Africa did not send its best swimmers to the event after they took part in the Commonwealth Games. Le Clos won seven medals at Commonwealths.
“I needed some time out from competing after the Commonwealths, not have the stress of competing all the time,” Le Clos said, according to SwimSwam.
Youth Olympians reunited for first time in 12 years
Olympic triathlon champion Gwen Jorgensen is pregnant and will not compete this year.
“Just kind of take this year a little bit easier,” Jorgensen said in a video posted on Facebook on Thursday.
The baby is due Aug. 3, according to Jorgensen’s social media.
Jorgensen, 30, became the first U.S. Olympic triathlon champion in Rio after going in as the heavy favorite. She has said for months that she planned to take time off to have a baby before returning to defend her Olympic title at Tokyo 2020.
Swiss Nicola Spirig, the 2012 Olympic gold medalist and 2016 silver medalist, is reportedly expecting a child in May.
In Jorgensen and Spirig’s absences, the top triathletes going into the season are defending world champion Flora Duffy of Bermuda, U.S. Olympians Katie Zaferes and Sarah True and Britons Vicky Holland and Helen Jenkins.
Jorgensen’s last competition was the New York City Marathon on Nov. 6, when she finished 14th in her first running race longer than 10 miles.
The World Triathlon Series kicks off in Abu Dhabi the first weekend of March.

The PyeongChang Winter Olympics, the first Winter Games in South Korea, are a little more than one year away.
A number of U.S. stars are establishing themselves in this winter sports season as medal contenders.
NBC Sports takes a look at some of those names to watch, as the U.S. looks to return to the top of the medal standings.
Russia earned the most medals at home in Sochi in 2014 with 33 medals, with the U.S. coming in second with 28. Those standings could change if Russian results are stripped due to its ongoing doping scandal.
The U.S. has never topped the total medal standings at a Winter Olympics outside of North America. It led the way at Lake Placid 1932 and Vancouver 2010.
