2019 Is The Greatest Year Ever For The Women's 1500 in the US
After I (Rojo) saw an American run 4:06.19 and finish 9th at USAs, I wondered, "Was that the greatest US-only 1500 race ever run? Is this the deepest year for American 1500-meter running in history?"
I did a little research to try to answer those questions and the answer appears to be yes to both. In terms of the actual USATF final, what impressed me about the race was not only the depth -- nine women under the Worlds standard of 4:06.50 -- but also how close the top four were. While Shelby Houlihan won as expected, the 2018 World #1 (or #3, depending on whose ranking you are using) was only 0.54 of a second away from 4th place (Sinclaire Johnson) and failing to make the team.
Track & Field News' archives of past USA results goes back to 1986, and during that span, this year's final was easily the deepest in terms of most sub-4:06.50s in a single race. The .54 margin between first and fourth was also the smallest since 2004, when the gap was just .51.
