Although the New Balance Nationals Indoor meet, along with the NCAA Division 1, 2 and 3 indoor championships were all cancelled as a precautionary measure due to the Coronavirus (COVID-19) pandemic, there were still world-leading efforts in China and South Africa, in addition to several national-leading high school marks in select states. View the choices and vote for the DyeStat Performance of the Week!
