With a secret veil surrounding the first half of the United States Nationals at King Mountain, the competition was held between July 20th and July 26th. Unless you were there, it was a mystery who won this competition until more than a week after the competition had ended. Results of the competition were withheld for some unknown reason and individual tasks results are still not available on the official website.
