American sprinters Sydney McLaughlin and Dalilah Muhammad finished 1-2 in the 400-meter hurdles at the Tokyo Olympics on Wednesday.

McLaughlin came from behind to run down Muhammad after the very last hurdle. She clocked in at 51.46 – breaking a world record. Muhammad finished with a 51.58, which also broke the original world record but finished behind the 21-year-old New Jersey native.

Muhammad had defied the odds coming into the Olympics. She battled coronavirus twice and suffered a hamstring injury but is still managing to leave Tokyo with a medal.

"It definitely was a journey just filled with so many ups and downs. So just thankful to God for getting me to this point. … Just so thankful, so thankful to end on a silver medal for the USA," she said.

It is McLaughlin’s first Olympic gold medal. She had won gold in the 2019 World Championships in the 4x400-meter relay and a silver in the same competition in the 400-meter hurdles.
