Preston returned to compete in American Ninja Warrior 7 in San Pedro for the special military event. His run was cut in qualifying, but he failed the I-Beam Cross, like many that day. However, he placed 16th overall and advanced to the San Pedro finals.

In the city finals, Preston got his revenge on the I-Beam Cross but he shockingly failed the Salmon Ladder again. This time around, he made the top 15 this time, placing 13th. Because of this, he became the first Olympic athlete in American Ninja Warrior history to compete in the national finals. He looked strong through most of the course on Stage One, but ultimately failed at the final obstacle, the Triple Swing.
