Starting Thursday, all of the hard workouts, the technique toning and the tapering that the swimmers and divers across Colorado have put in will come to fruition. They’ll all be battling for state championships on the individual level and as a team.

Divided into three classifications, several local athletes and teams have a chance to etch their names into the CHSAA’s history books. Class 4A looks to be the most exciting for teams from Boulder and Broomfield counties, with Broomfield, Monarch and Centaurus vying for the team title. Broomfield is fresh off of winning the inaugural Granite Peaks League title against 3A, 4A and 5A teams alike.

Pine Creek dominated 4A last year, winning with 567 points, but Broomfield claimed second with 265 to beat out fourth-place Monarch by just 14.5 points. Pine Creek’s move up to 5A this season opens up a path for the Eagles, Coyotes and Warriors — fifth last year — to take the top spot.

Fairview’s Amelia Mason and Holy Family’s Lorelai Frauenfelder have had spectacular seasons and will be in a prime position to win an individual title or two, maybe more.

The 5A diving competition will begin on Thursday morning at the Veterans Memorial Aquatic Center in Thornton, with 5A swimming finals set for Friday, 4A finals set for Saturday and 3A finals set for Tuesday.

Here’s what the top-10 rankings look like for each event, based on a relay team’s or individual’s best performance of the regular season.
