US Olympic Trials start tomorrow at (where else but...) Eugene. They will extend all the way to the 30th. Here are some of my random thoughts, add your own below.
Note - in the marathon, the US could move someone up to take the spot of a different qualified athlete. You can't do that on the track. If you are top 3, but not qualified, you don't go. For most events, this will not be an issue.
10,000 m - This is the even that the above could be an issue. The men's final will be tomorrow night and only Fisher, Young, and Kincaid have the auto-time and Chelimo is in the quota. Mantz or Chelanga could possibly move up enough if they win in a fast enough time. It will likely be hot and
