Early Life & Education
Kai Beckstrand was born on November 11, 2005, in St. George, Utah, a scenic desert city in the southwestern corner of the state known for its red rock landscapes and outdoor recreation culture. He grew up in a large, athletic family where physical fitness was not just a priority but a way of life.
His journey into ninja warrior competition began almost by accident. When Kai was seven years old, one of his siblings requested an American Ninja Warrior-themed birthday party. His father, Brian Beckstrand, began building homemade obstacles in their backyard to make the party special. What started as a fun family project quickly evolved into a full-blown training facility. At its peak, the Beckstrand backyard contained between 40 and 50 scaled obstacles modeled after those seen on the show.
Kai attended local schools in St. George and later became a certified firefighter and EMT, following in the footsteps of his father, who serves with the St. George Fire Department. His education in emergency medicine has given him a disciplined, safety-first mindset that complements his high-risk athletic career.
Career Journey
The Backyard Origins and The Grip (2012–2017)
The Beckstrand family’s backyard operation eventually outgrew its space, leading Brian and Holly Beckstrand to open The Grip, a 13,000-square-foot ninja training facility in St. George. The gym became a hub for the local ninja community and the training ground for what would become one of the most formidable families in the sport. Kai spent his childhood and early teenage years refining his technique on professional-grade obstacles alongside his siblings.
American Ninja Warrior Junior and Child Prodigy Status (2018–2019)
At just 12 years old, Kai made his television debut on the inaugural season of American Ninja Warrior Junior in the 11–12 age division. He dominated the competition from the opening episode, winning his seeding round, knockout round, and final showdown races to advance to the semifinals.
In the finals, he defeated Ella McRitchie and then Tate Allen in the championship race, becoming the first-ever 11–12 division champion and taking home $15,000. His performance was defined by a maturity and speed rarely seen in someone so young.
He returned for American Ninja Warrior Junior 2 in 2019, now competing in the 13–14 division. He once again advanced to the finals but fell on the Crazy Cliffhanger, finishing in fourth place overall and earning $2,500.
Rookie Sensation on American Ninja Warrior (2021)
Kai made his adult American Ninja Warrior debut in Season 13 at age 15—the minimum age for competitors. Running after his father Brian in the fifth qualifying episode, he not only completed the course but posted the fastest time of the night at 1 minute 36.83 seconds. The father-son duo became the first in the show’s history to both hit qualifying buzzers in the same season.
In the semifinals, Kai punched his ticket to the Las Vegas National Finals, where he cleared Stage One with 17.71 seconds remaining. His rookie season ended on Stage Two at the Striding Steps, but he had already announced himself as a future star.
The Heartbreak and the Mega Wall (2023)
After sitting out Season 14, Kai returned for Season 15 in 2023 at age 17. He once again blazed through qualifying in under a minute, earning a shot at the newly raised 18.5-foot Mega Wall. He conquered it on his first attempt, becoming the first ninja of the night to claim the $10,000 prize.
In the semifinals, he posted the fastest time and advanced to the Safety Pass race, where he lost a nail-biter to Kaden Lebsack. At the National Finals, however, disaster struck: he failed the Jumping Spider on Stage One after going too fast into the chute, causing his right foot to land ahead of his left. The fall was one of the biggest shocks of the season.
Redemption and Stage Four (2024)
Season 16 in 2024 was Kai’s coming-out party as an elite contender. Competing alongside his brother Luke and mother Holly, he once again posted the fastest qualifying time (1:06.03) and cleared the Mega Wall for a second consecutive season, this time winning $20,000.
In the semifinals, he set a blistering 36-second course completion—an all-time record—and won the Safety Pass race against Kaden Lebsack, advancing to Vegas with a safety net. He got his revenge on the Jumping Spider, cleared Stage One with 43 seconds to spare, and dominated Stage Two with the fastest time of the night. On Stage Three, he became the first competitor shown in the broadcast to clear the entire stage, making it to Stage Four.
On Stage Four, he timed out around the 70-foot mark of the rope climb, reaching the buzzer in just under 50 seconds. He finished fifth overall for the season—his best result yet and proof that a championship was within reach.
The Championship Season (2025)
Season 17 was Kai’s coronation. In the fifth qualifying episode, he once again conquered the Mega Wall—his third straight season doing so—and won another $10,000. In the semifinals, he cleared the course with the second-fastest time behind only his brother Luke.
At the National Finals, the new racing format played to his strengths. He won his first race against Jessie Graff, his second against Donovan Metoyer, and his third against Isabella Folsom. In the knockout rounds, he defeated Folsom again, then David Bergstrom-Wright in the Round of 16.
The most emotionally charged race came in the Round of 8 against his own brother Luke. After a close call on the Floating Monkey Bars, Kai caught up at the Kickboards and won after linking his moves on the Falling Shelves. He then defeated Isaiah Thomas to reach the finals, where he faced Noah Meunier. When Meunier failed on the Falling Shelves, Kai hit the championship buzzer and collapsed to the stage in tears.
At 19, he became the American Ninja Warrior Season 17 champion, taking home $250,000 and becoming the first Utahn to win the show in a decade—since Isaac Caldiero in 2015.
Defending the Title (2026)
As of 2026, Kai is competing on American Ninja Warrior Season 18 alongside his father Brian, brother Luke, and sister Baylee.
