The Top 7 Events At USA U20 Championships To Keep An Eye On

Video: Athing Mu ran 2:01.38 at the Music City Distance Carnival

1. Athing Mu Versus Roisin Willis In The 800m

Field: Athing Mu (Trenton Central, NJ), Roisin Willis (Stevens Point, WI), Alyssa Brewer (Southern California), Victoria Vanriele (Governor Livingston, NJ), Dominique Mustin (North Canyon, AZ), Morgan Foster (Chandler, AZ), Nyjari McNeil (San Diego St.), Marlena Preigh (RISE, CO), Brynne Sumner (Woodstock, GA)

Why: There's a built-in storyline for this one. As Mu was attempting to break 2-minutes in the 800m indoors at New Balance Nationals Outdoor, it was Willis who eventually caught the Trenton Central Track Club star down in the final moments and claimed the title instead ...as a freshman. Things remain compelling after Mu went 2:01.38 at the Music City Distance Carnival -- versus professionals -- and Willis clocked 2:04.86 to win Brooks PR. Mu still has yet to prove she's unbeatable in a more tactical race featuring high school runners, but this will be a good window into the question. Brewer, fresh off her first season with the Trojans, ran 2:04.93 in March, while Vanriele is quietly looming with her 2:05.15 from Brooks PR as well. Expect this race to be tactical on Saturday and Sunday.
