Nobody knows if they’ll open up a significant number of spots in the races. At this point, there have been a few instances of a very small number of bibs trickling onto the registration site, so your best bet is to monitor it as closely as possible.
My pure speculation is that they’ll wait and see if W&D can be held. If it can, they’ll look at how well the precautions they put in place worked and decide if a higher capacity could be managed for Marathon Weekend. That’s when I’d expect to see a larger bib release, if it happens. Signs don’t look good so far, though, with the continued cancellation of fall races.
Good luck!
