Stewart, a senior from Spanish Fork, Utah, ran in the 400-meter preliminary and took eighth in her heat with a time of 53.84. The top two from each heat plus the next best two overall advanced to the final.
"We were hoping Natalie could go after her lifetime best and the school record in the 400 but she just felt a little tight," BYU coach Patrick Shane said. "She went and ran her heart out and she ran a solid race. Natalie was in there with some great competition and represented very well. I’m proud of her."
Brown, a junior from Orem, Utah, took fourth in the second 800-meter heat with a time of 2:04.36. With one heat to go, Brown was in position to qualify but the third-place runner in the final heat edged her time by 0.16 of a second to take the eighth spot in the final. Brown finished ninth overall.
"That was tough on her to be the odd one out but she ran a smooth and even race," Shane said. "She was in a very competitive heat and was in second coming down the home stretch but she got caught at the tape. Kelsey ran her heart out and laid it on the line. She gained a lot of valuable experience that will help her next year when she’s a senior."
