Watch live: 6:15 PM Thursday
What kind of race will this be? If it's a slow one, Watson is the one to beat with her near-undefeated record and 2:00 PR. (Though she did get outkicked in a tight race with Stephanie Jenks in Boston this winter) South African Simonay Weitsz has a 4:22 1500 PR; that converts to 4:42y which outpaces Watson (4:47), Hurta (4:47), McArthur (4:47), and Bowen (4:43 1600). If it's 2:22 or slower at halfway, that opens it up for the Americans.
