Jack returns to Covenant this year as one of five sophomore runners for the Scots this season. Prior to Covenant, Jack ran for Castle Hills First Baptist School where he was named to the Academic All-Conference team in his senior season.

His parents are Joel and Jan Williams. He has one younger sister, Julie. When he is not running, Jack enjoys watching anime, reading, and climbing trees (and reading in them). One of his favorite Bible verses is Ecclesiastes 11:13 which says, "Let us hear the end of the matter: Fear God and keep His commandments for this is the whole duty of man."

Jack is majoring in French and minoring in History. After graduation, he would like to do some form of government work, such as working for the Department of the Air Force or the State Department.
