McKinney said Hempel ran with the pack in the boys race until just past the one-mile mark.
"He just kind of jumped out and never really looked back," McKinney said.
The Danville coach said both Hempel and sophomore Jamie Grey, who was fourth, ran their best races of the year even though they did not run their lowest times.
Stephan Crown-Weber, the only senior among the Admirals' top six runners, was sixth, less than a second behind Grey.
"I'm proud of Stephan. He's been the guy that's really an-chored our team," McKinney said.
Junior Aaron Fons was ninth for Danville, followed by Jeff Ricker (22nd) and Reid Williams (34th).
Danville's girls were no match for a Trimble team that placed six runners in the top nine places and scored just 18 points. Trimble was coming off a win last weekend in the girls Class A division of the KTCCCA Meet of Champions, a large race usually considered a preview of the state meet.
"I'm proud of our girls," McKinney said. "Racing them on their home course, we knew we had our hands full."
Danville's top six runners finished in three pairs, led by fifth-grader Kaitlin Snapp in fourth place and freshman Molly Pittman in fifth. Diamond Pace and Brittany Baierlein were 10th and 11th, respectively, and Morgan Young and Maddie Meckes were 16th and 17th. Sarah Vonderbrink was 20th.
Both Danville teams will advance to the state meet this Saturday at Lexington, along with one individual qualifier from Burgin, Beverly Harris, who was 23rd.
Class AAA, Region 6
At Somerset, Jordan Wilkinson finished second overall and helped the Lincoln County boys earn the team qualifying spot they couldn't get last year.
Lincoln was two points out of fourth place and the final qualifying spot a year ago, but on Saturday the Patriots finished comfortably in fourth, 57 points ahead of the nearest challenger.
Wilkinson, a freshman, posted a time of 17:49 at General Electric Park to finish just 12 seconds behind Pulaski County's Patrick Jenkins.
Senior Brandon Sanders was 11th and sophomore Nate Todd was 16th for Lincoln.
Lincoln didn't field a full girls team, but two runners qualified individually: senior Brittney House (sixth) and freshman Jesslyn Long (26th).
