Rupp hasn't raced since winning the Olympic Marathon Trials in February.
But today, the Eugene Marathon tweeted this:

Gotta figure that the American record is in play. In fact, if Rupp has been building his fall training around this and targeting this race specifically, I would expect it to fall. As a reminder, the AR is 59:43 by Ryan Hall from 2007.
