DES MOINES, Iowa — North Union junior long-distance standout Riley Bauer captured second place in the 3,200-meter run during the Iowa Class 1A state track & field competition on Thursday.

Bauer, who earned a bronze medal in the 2-mile run at the 2016 state meet, crossed the finish line at Drake Stadium in 9:29.85 to claim the silver medal.

Central Lyon junior extraordinaire Gable Sieperda shattered the Class 1A boys 3,200-meter run record by beating Bauer to the wire in a winning time of 9:15.30. Sieparda’s gold-medal time broke the previous Class 1A state mark of 9:18.22 set by Gehlen Catholic’s Paul Barnhart in 1986.

Bauer, who produced his personal-best time in the 3,200 by a staggering 20 seconds, and Sieparda will square off again in Saturday’s 1,600-meter run at 2:15 p.m. in Des Moines. Bauer is the defending Class 1A state champion in the mile.

Bauer will anchor North Union’s distance medley relay team of Blake Crawmer, Derek Thompson and Trent Pedersen at noon today at Drake Stadium. The Warriors’ foursome qualified for state with a time of 3:41.98.

Thompson and teammate Kyarsten Mullen each competed in Thursday’s sprint preliminaries, with neither North Union athlete advancing to the final round.

Mullen just missed advancing in the 100-meter dash, placing 10th — just two spots away from Saturday’s finals. The North Union senior speedster crossed the finish line in 12.95 during Thursday’s prelims.

Sigourney’s Autumn Barthelman posted a first-place time of 12.49 in the open 100, while Meskwaki’s Grace Tahahwah claimed the eighth and last qualifying spot in 12.83.

Tahahwah earlier captured the top spot in the 200-meter prelims with a time of 26.08, while Graettinger-Terril/Ruthven-Ayrshire’s Toni Alesch claimed the final qualifying spot in 26.97.

Mullen, who advanced to state with a time of 27.67, lowered her time by crossing the finish line in 27.4 to net 16th place in Thursday’s 200 prelims.

Meanwhile, Thompson placed 15th in the boys’ 100-meter dash’s prelims on Thursday and will not advance to Saturday’s final.

Lisbon’s Derek Bova won the open 100 prelims in a time of 10.94, while Central Lyon’s Riley Van Wyhe claimed the eighth and final qualifying bid in 11.30.

Mullen will lead off North Union’s 4×100 relay team in today’s 12:40 p.m. race at Drake Stadium. Mullen joined forces with Rory McClelland, Alexis Valvick and Olivia Marlow to post a qualifying time of 53.29.

North Union’s Elliott Hagebock will open today’s Class 1A state competition at 9 a.m. in the high jump. Hagebock reached Des Moines by clearing 5-10.
