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, clearing the Quintuple Steps, Rope Swing, and Rolling Barrel with ease. He even became 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 again tried in American Ninja Warrior 2, but failed the Cross Bridge. Sims returned in American Ninja Warrior 4, but he failed on the Swing Circle like many that day. He then came back for American Ninja Warrior 6 in Miami and for the first time in his ANW history he beat the course with the 12th fastest time. In the Miami Finals Course, he went out on the Dancing Stones after slipping on one of them and missed his chance at making it to Vegas. He's popular for wearing american shorts when competing. 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.

He missed 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.

His training is based on Parkour and Freerunning, disciplines which are really complete on all aspects.In Youtube, loads of videos were uploaded about his practice of Parkour, those videos allowed him to obtain popularity from all over the United States.


  • 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.
  • Coincidentally, both him and Carbone competed in the Daytona Beach finals.
