Kapaun Mt. Carmel junior Ava Claassen won the Class 5A state cross country championship Saturday, Oct. 31, clocking 16:59.16 at Rim Rock Farm.

The time broke the girls 5K course record of 17:09.77 set by Salina Central's Katelyn Rupe in 2024, according to the Wichita Eagle. Of the 292 girls who competed across three classifications at Rim Rock Farm, nobody finished within 56 seconds of Claassen.

It was the final prize in a fall season unlike anything Kansas high school distance running has seen.

Salina Central senior Kaylie Shultz, who beat Claassen for the 5A title a year ago, finished runner-up in 18:12. Last fall, Shultz won in 17:26 with Claassen 10 seconds back at 17:36. This year, despite more challenging racing conditions, Claassen lowered her time by 37 seconds.

An all-time record at Brown Thrush Park

Claassen's state title capped an undefeated seven-race season. She won five of those races by more than a minute, including three by at least 1:50. Her closest challenger all season finished 41 seconds behind her.

The signature performance came Oct. 3 at Brown Thrush Park in Wichita. Claassen finished in 16:20.74, the fastest 5K ever recorded by a Kansas high school girl. The time shattered the previous all-time state record of 16:32.62 set in 2024 by Ryin Miller of Topeka Seaman.

The Wichita Eagle reported that the performance ranked as the sixth-fastest girls high school cross country 5K time in the country this season, according to MileSplit's national database. Claassen won that race by 1 minute, 50 seconds.

She broke 17 minutes three times this fall. The next-fastest 5K recorded in Kansas this season was 17:24.

A rapid rise

Claassen's trajectory has been steep. As a freshman, she finished 10th in the state 3,200-meter race on the track and failed to qualify for state in the 1,600.

By her sophomore spring, she broke the Kansas all-time girls 3,200-meter record with a 10:01.55 at the Shawnee Mission North Relays, surpassing the previous mark of 10:07.96 set by Molly Born. She then swept the 5A distance titles at the state track meet in Wichita, winning the 3,200 in 10:04.27 and the 1,600 in 4:45.15. Both were classification meet records. She also helped Kapaun win the 3,200 relay in another 5A meet-record performance.

Claassen now owns the Kansas all-time records in both the track 3,200 and cross country 5K, the Rim Rock course record and multiple state championships.

She is still only a junior.

Race strategy at Rim Rock

Kapaun coach Gretchen Bina and Claassen developed a careful strategy for the championship race. Rim Rock's relatively flat opening mile can tempt runners into starting too aggressively before the course turns hilly. Claassen settled into a controlled pace before attacking the hills, where the Eagle reported her improved strength made the biggest difference.

What's next

Claassen has built her reputation competing almost exclusively in Kansas, without regularly testing herself against national competition. That changes Nov. 15 at the Nike Cross Regionals Heartland Championships in Sioux Falls, South Dakota. She hopes to qualify for the Nike Cross Nationals on Dec. 5 in Portland, Oregon.

Bishop Carroll and Kapaun combined for five top-five individual finishes and four top-five team finishes in the 5A races, the Eagle reported. Carroll's girls placed third with 96 points. Andover Central finished fourth with 129 points, followed by Kapaun in fifth at 134.
