Olympic 2016 Results: Tracking Sunday's Medal Count for Each Country

Michael Phelps fittingly completed his 2016 Rio Olympic Games, and likely his career, with a gold medal.

It was the 23rd gold and 28th total medal of his incomparable run through international swimming competition.

"Getting off the bus, walking into the pool tonight, I almost felt myself starting to cry," Phelps said, per NBC's Rachel Lutz. "Last warm-up. Last time putting on a suit. Last time walking out in front of thousands of people representing my country. It’s insane."

As Phelps waves goodbye to the Olympics, the track and field stars are ready to say hello. On Sunday, gold will be awarded in the men's 100-meter and 400-meter sprints, as well as the women's triple jump.

Hardware in gymnastics, wrestling, sailing and more will be handed out in Rio. To stay up to speed with all the action, follow the live-updating medal count below:

History in the Women's Marathon

Jemima Sumgong became the first woman in Kenyan history to win the Olympic marathon with a time of 2:24:04. Bahrain's Eunice Jepkirui Kirwa and Ethiopia's Mare Dibaba won the silver and bronze, respectively.

The BBC shared a photo of Sumgong as she approached the finish line:

Americans were represented well in this race. Team USA's Jenny Simpson tweeted a photo of Shalane Flanagan, Desiree Linden and Amy Cragg, who finished sixth, seventh and ninth, respectively:

"It's not what I dream of," Flanagan said of her sixth-place finish to NBC's Lewis Johnson. "I ran as hard as I could. ... I did everything I could."

Action All Over Rio

Later on Sunday, Jamaica's Usain Bolt will compete in the semifinals of the men's 100-meter sprint around 8 p.m. ET. If he advances, he'll run the finals about an hour later.

A gold for Bolt in the 100 would be historic, per Victor Mather of The New York Times:

"

Usain Bolt has not lost an Olympic race since 2008, dominating the 100 and the 200, while also powering the 4x100 relay with Jamaica in Beijing, and then again in London. Tonight, he’ll try to become the first man to win the 100-meter dash three straight times. Standing in his way are a bunch of young speedsters and one familiar rival: the American Justin Gatlin.

"

In gymnastics, rising star Simone Biles will be back on the mats for a routine in the the vault finals. Her teammates, Gabby Douglas and Madison Kocian, will be in the finals for the uneven bars.

Back on the track, Team USA's LaShawn Merritt hopes to take down defending Olympic champion Kirani James in the men's 400-meter dash.
