Hall is planning on running the first half in 69:40, while the next group is slated to hit halfway in 71:30. Kellyn Taylor, Stephanie Bruce, Emma Bates, and D'Amato are among the US stars chasing PBs in the desert.
There have only been six races in history in which multiple Americans have broken 2:10 (the record is four guys under 2:10, achieved at the 2012 Olympic Trials). But with seven of the top 12 finishers from the Trials entered on Sunday, we could see as many as half a dozen Americans break the barrier in Arizona.
Let this serve as your official "American record alert." While Ryan refused to use those words, he said he'd like to see Sara go out in 69:40 so we'll let you do the math. "This has been the fittest I've ever seen her. Every buildup she gets better and better," said Ryan.
