2018 Winner: Athing Mu, Trenton, New Jersey, 2:06.59
Armory Record: Samantha Watson, Henrietta, New York, 2:01.78
National Record: Sabrina Southerland, Queens, New York, 2:03.59
Analysis: After setting the new American Record time of 1:23.57 in the 600m earlier this season at the USATF Indoor Track & Field Championships, Mu became the clear favorite in this race. Her time in the 800m of 2:03.98 ranks US No. 1. If Athing were to have an off day, the next closest athlete to be able to claim the title would be Wisconsin's Roisin Willis. Willis, who is just a freshman, threw down the third fastest time of the year at the MileSplit / SPIRE Scholastic Showcase. She could be a dark horse as she's only raced the 800m twice this year and dropped three seconds from 2:09.57 to 2:06.91.
