Sydney Holiday was on fire.
The Broomfield senior cruised through the rounds of the 60, running 7.55, 7.51, and then her masterpiece - a 7.46 for a US No. 6. Her 7.46 victory in the 60 final was a PR of nearly a tenth of a second.
Teagan Zwaanstra took the runner-up spot, running a PR of 7.61.
WATCH: Sydney Holiday Runs 7.46 In The 60 For A US No. 6
Holiday nearly captured the sweep of the sprints - if not for Amarachi Onuoha's big run in the 200. The two went head to head in the 200 final after running identical 25.25s in the prelims. Onuoha taking the W in in the final, however, running a PR of 24.80.
And Onuoha nearly had her 2-2, as she pushed Lily Williams the distance in the 400. Onuoha set a hot early pace, forcing Williams to chase late - something she's proven to be comfortable with.
Williams' patience paid off, however.
The Grandview senior kicked hard, and late, to take the 400 in a state-leading 57.55. Onuoha was a stride or two back in 58.11.
Riley Stewart toed the line for the first time since Nike Cross Nationals in December. The Cherry Creek sophomore ran away with the 800 just off her PR, running 2:16.43.
Moving up in distance...
Sydney Thorvaldson came, saw, and conquered.
The Rawlins High (Wyoming) senior erased the meet record books in the mile and the 2 mile. We'll start with her Friday night 2 mile performance...
Thorvaldson - who finished third at Nike Cross Nationals this past December - soloed a stellar 10:31 2 mile, lapping most of the field. The time is a US No. 3 without any altitude conversion.
Cameron McConnell and Lucca Fulkerson finished second and third, running 11:22 and 11:23.
And Thorvaldson wasn't done.
She doubled back Saturday to dominate a high caliber mile field, running another big-time meet record of 4:53 - a US No. 6 without an altitude conversion.
While Thorvaldson was the big winner in the mile, another big winner was eighth-grader Bethany Michalak, who went head to head with Colorado's best high schoolers and came out on top.
Michalak ran a PR of 5:08 to finish second.
The girl's high jump also lived up to the hype, as Riley Masten and Daniella Munoz went inch for inch. Both went 5-6, while Shayla Padilla took third in 5-4.
Agur Dwol shook up the national rankings in the triple jump. The Mullen sophomore went big - leaping to a US No. 4 of 40-3.75. That's a PR of nearly two feet for Dwol.
In the pole vault Mia Manson continued to be the last woman standing.
The Monarch senior went 12-6 to win the competition by a foot over Lilly Nichols.
The long jump was another hotly contested affair, with Sadie McMullen and Zwaanstra taking this one into the inches.
McMullen prevailed in the finals, leaping over Zwaanstra's 18-7.75 with an 18-8.
