The race that can give us real insight into the race for the US team for Budapest is a very interesting looking women's 5000m:
Katelyn Tuohy, Emily Infeld, Josette Andrews, Whittni Orton-Morgan, Elly Henes, Allie Buchalski, with Laura Galvan and Jess Judd for Mexico and GB. Only thing missing is Monson, Cranny, and Schweizer then you've got the a US final caliber field. Given this is sponsored by ON I'm hoping Monson gets added soon since these are just early entries.
