As promised I am joined by Johanna Gretschel (@jojo_shea) to preview and predict all things USAs, which start tomorrow night on NBC Sports Gold. US titles and World Championship spots are at stake. We give previews and picks for all events from 800m to 10K, discussing each in order of the finals. We start with the 10Ks which both start tomorrow night. Tune in then and then on NBC networks throughout the weekend to catch all of the action.
