Allie has the #2 seed time with 9:31. Gen Lalonde from canada has run 9:29 this year in Shanghai DL.
Lalonde is probably the favorite as her 3 steeples this year were all between 9:29 and 9:34. 4:08 1500m PB
Ostrander hasn't competed internationally besides at Pre this year. Likely has a higher ceiling but she's been competing basically all year and will not be peaking.
not to ignore anybody else, the US has Marisa Howard with a 9:30 PB, 9:36 SB. Caseta from ARG has run 9:25 but only 9:40 this year. Lastly, Regan Yee from CAN has run 9:35 this year but got dusted by Lalonde at their natl champs.
