The track and field medal events at the Tokyo Olympics have produced some of the most memorable moments of the Games.
On Day 12, the United States' Sydney McLaughlin became the latest runner to drop a world-record time. McLaughlin bested her own world record in the women's 400-meter hurdles.
Canada's Andre De Grasse created his own special moment inside the Tokyo Olympic Stadium in Day 12's second track session by besting a trio of Americans to win the men's 200 meters.
De Grasse finished in third place in the men's 100 meters and had a long list of silver and bronze medals at major events before capturing gold on Wednesday morning.
The United States is still on top of the overall medal table with 79 medals. China sits in second place with 70 medals. China still has the edge for the most golds with a 32-25 lead on the Americans.

Sydney McLaughlin Sets World Record In 400-Meter Hurdles
McLaughlin set the world record in the 400-meter hurdles for the second time this summer.
The 21-year-old American dropped a time of 51.46 seconds to defeat fellow American Dalilah Muhammad.
Muhammad was out in front for the first half of the one trip around the track. McLaughlin raced with a steady pace and then surged ahead in the final 100 meters.
McLaughlin's push to the finish line helped her shatter the world record time she set at the United States Olympic Trials in June. McLaughlin's previous world record was set at 51.90 seconds.
The performance came one night after Norway's Karsten Warholm set the men's 400-meter hurdles world record that he previously set before the Olympics.
McLaughlin's gold was the third medal of that color for the United States in track and field. Athing Mu took first in the women's 800 meters, and Valarie Allman won the women's discus.
In total, the United States owns 16 track and field medals, and half of the medals on the men's and women's side are still up for grabs.
If the United States meets its high expectations in track and field, it should push the overall medal haul close to 100.
Andre De Grasse Finally Captures Gold
The Olympic gold medal was the last thing missing from De Grasse's extensive resume.
The Canadian sprinter earned a silver medal behind Usain Bolt in the men's 200 meters in 2016 and was third in the men's 100 meters in Rio de Janeiro and Tokyo.
De Grasse, a former 100 and 200 meters NCAA champion at USC, bested a field of talented Americans on Wednesday morning to add the gold to his medal cabinet.
De Grasse finished in 19.62 seconds. a time that was good enough to set a new Canadian record.
American Kenny Bednarek set a personal best time of 19.68 with his second-place finish, while pre-race favorite Noah Lyles earned a season-best mark of 19.74 to take the bronze.
American teenager Erriyon Knighton took fourth behind the experienced sprinters in a time of 19.93. The first five finishers ran under 20 seconds.
De Grasse's gold was the fourth one earned by Canada in Tokyo. The women's eight rowing team, Maggie McNeil in the women's 100-meter butterfly and weightlifter Maude Charron also topped the podium for Canada.
