Brett Sims (ブレッド・スイムス) (Greenville, South Carolina, 14 April 1986) was the runner-up of the first American preliminary competition, the American Ninja Challenge. Because of this, he qualified to compete in SASUKE 19. There, he made it to the Jumping Spider but fell as many did that day.
He was invited back to compete in the following tournament, SASUKE 20 as well. There, he got farther, despite competing with an injured foot. However, due to his injury he struggled on the Spider Walk portion of the Jumping Spider, and he timed out on the Soritatsu Kabe.
Sims entered into the American Ninja Challenge 4 but his entry video did not make it into the top 3.
He also competed in the American Ninja Warrior trials. He had a brisk early pace, becoming the first person of the day to clear the Spider Jump. However, he shockingly failed the Pipe Slider when on the second jolt, the bar became uneven and the right side slipped off the tracks, ending his run.

He then came back for American Ninja Warrior 6 in Miami and for the first time, he beat the qualifying course, finishing with the 12th fastest time.
In the Miami finals Course, he went out on the Dancing Stones after slipping on one of them, ultimately missing his chance at making it to Vegas.
American Ninja Warrior 8
He also competed in Season 8 clearing Atlanta qualifiers. He was later one of the few competitors to finish the city finals course, making it his first time to make it to Las Vegas. He ultimately timed out at Warped Wall in stage 1 after several failed attempts to get up the wall.
American Ninja Warrior 9
He missed out on ANW3, 5, and 7. However, Sims has confirmed on running American Ninja Warrior 9 after his performance last year, making it his first time aside from the first season to compete on an odd-numbered season. His run was cut in qualifying, but he finished the Daytona course with the 7th fastest time. His run in the city finals was digested but it was shown that he failed the Salmon Ladder, despite using the cross grip, not making it back to the national finals.
Additionally, Sims also participated in the obstacle-design challenge this season, and was one of the challenge winners, designing the ninth obstacle of the Kansas City finals, known as the Iron Maiden.
Sims returned to the sport in American Ninja Warrior 10 in Miami. He was one of only 11 to complete the qualifying course, placing fourth. Sims had made a bet with training partner Ryan Stratis, stating that whoever fails the course has to shave off his beard. Fortunately, neither of them needed to, as both finished the course.
His city finals run was digested but it was shown that he got revenge on the Salmon Ladder, and managed to clear the whole course and placed 2nd overall. Because he and Ryan Stratis completed the course, the bet continued in Stage 1 of the national finals.
Eventually, Sims failed the Double Dipper on Stage 1. He lost the bet to Stratis, who made it to Jeep Run before failing. During broadcast, he was shown getting his beard shaved after both of their runs in Vegas.
It is also notable the Sims had ran the course in Miami on his birthday. The taping of the Miami course took place on April 14, taking place during Sims' 32nd birthday.
- Sims is one of two obstacle-design winners in American Ninja Warrior 9 to also compete on the course, along with Kevin Carbone. Unlike Carbone, however, Sims is the only one to have competed beforehand. Both him and Carbone coincidentally competed in Daytona Beach on the same season.
- Sims is the third competitor whose birthday occurred while running the course, after Natalie Strasser in ANW 4's course and Daniel Gil in ANW8's Oklahoma City qualifiers
