This list represents a best attempt at capturing all sub 1:46:00 performances for U.S. Women. While the list is not 100% complete from a performance standpoint, it should completely capture all sub 1:46:00 performers. Thanks go to Curt Clausen, Bob Bowman, Ed Parrot, and Jack Mortland as they were the original source of much of the data presented.
