Kambri Muir crossed the finish line several strides in front of the others, took a deep breath and looked at the scoreboard. 

As her time flashed across the screen, the weight of the moment came over her. She cried out in joy and fell to the ground. 

Months after suffering a serious injury, the Salem Hills senior had broken the state record in the 5A girls 300-meter hurdles with a time of 42.57 seconds at the Utah State track and field championships Saturday. 

“The greatest thing that I could have ever done, and I’m so proud,” Muir said Saturday at the Clarence F. Robinson Track on the campus of Brigham Young University in Provo. “It’s so cool. It hasn’t really even hit yet. I had a really scary fall at the beginning of the season … and here I am. I’m so grateful that I was given this opportunity to come out here and break the record. I’m really proud of myself.”

Muir also won the 100-meter hurdles (15.01) and anchored Salem Hills’ 4×100-meter relay victory, powering the Skyhawks to a 58-point finish, tied with Springville for second place in 5A. 

Other strong Utah Valley girls finishers across the three-day championships were Timpview’s Lily Alder, who swept the 5A 3200-meter, 1600-meter and 800-meter races, and Lone Peak, which placed second in 6A (92.5 points) behind its strong distance team.

It was Muir’s feat that stood out, though, considering what happened at a meet earlier this season. She said she fell over a hurdle, hit her head and was knocked unconscious for approximately 45 minutes, sustaining a serious concussion. 

Her immediate focus was to get better. Muir said she took her recovery seriously, listening to her trainer, following concussion protocols and staying mentally resilient.

“My mindset was I was refired up, and I wanted it more than anything after that moment,” Muir said. “There were so many people doubting me and thinking that I couldn’t do it, so I had to put it out there and put it on the track and show that I could do it.”

Muir returned to the track in April, and picked up where she left off, securing personal bests in both hurdle races that month and again at the BYU Invitational the first weekend in May. 

Saturday morning in the 100-meter hurdles, she had a poor start, forcing her to jump on her non-dominant leg. She won anyway. Just hours later in the 300-meter hurdles, Muir surged ahead of the pack and sustained her pace in what she called a “tough race” to pull out a time no one in 5A or 6A has ever run before. 

The achievement was a prep career in the making, and required hurdling challenges on and off the track. Now she’s etched in the record books. 

“That’s everything that I’ve ever hoped for,” Muir said. “I’ve worked for four years for this, and I finally got it. It’s just an incredible feeling.”

The day was also a memorable one for identical twins Brielle and Zoey Nilsson from Lone Peak, who went first and second in the 6A girls 800-meter run, with Brielle finishing in 2:12.37 seconds and Zoey in 2:13.75 seconds.

Zoey said she told Brielle during their warmup they were going to finish one and two, and then went out and made it happen. It was a fitting conclusion to a successful prep career for the University of Utah-bound seniors.

“It’s honestly been one of the best experiences I’ve ever had,” Brielle said of running with her sister. “We definitely had to learn freshman year how to race together and not against each other, but I honestly can say that ever since then, we’ve never really seen each other as competitors, but we just both want each other to do the best we can.”

Zoey said they have leaned on each other amid physical challenges, such as a stress fracture and a lengthy illness, to get better.

“Seeing her just go get it only inspires me more, and I feel like seeing her come down the home stretch in front of me was only a motivator of, like, let’s go get one and two,” Zoey said.

Brielle also placed second in the 1600-meter (4:58.56) Saturday morning and Zoey was fifth (5:01.44). The duo was happy to contribute to the Knights’ second-place finish.

“Our team is a very distance-oriented, and so we get points in the mile and the 800 … it was just so cool to have so much of our team in the race together,” Brielle  said.
