This is the tentative roster-
For the women's 5 and 10 this is who is listed -
5,000 - Molly Huddle, Amy Hastings (B), Angela Bizzarri (x), Jen Rhines (B).
10,000 - Shalane Flanagan, Kara Goucher, Jennifer Rhines, Desiree Davila.
I think what would make the most sense would be to send Huddle and Rhines in the 5 and Flanagan, Goucher, and Davila in the 10. But for that to work it seems like Hastings would have to drop out of the 5.
