The state meet, at National Trail Raceway in Hebron, which is east of Columbus, ends the 2013 season, is Saturday.
Howell, in Division I and Miller, Division III, are running as individuals.
Howell is scheduled to run in the last race at 3 p.m. Miller is slated in the first race at 11 a.m.
Howell, who ran broke his own school record with a 15:50.48 in the regional Saturday at Tiffin, is making his first state appearance. He is also the first Norwalk runner to qualify to state in Division I in cross country.
“I felt like all my hard work had paid off,’’ Howell said. “I was ranked from 10th to 20th going in, so I was on the bubble. I knew coming in I could make it out. I’ve been hanging around 16:20 all year, but knew I could go faster.’’
Howell finished second in the Northern Ohio League tournament, fifth at district and fourth at regional.
“The entire season he’s been averaging in the 16:20s at most meets,’’ Truckers coach Drew Karnehm said. “He’s had it in him; we were just waiting for that break out race. You could see the confidence growing.”
Howell started running cross country as a freshman.
“He has that natural ability to run long distances,’’ Karnehm said. “He put in more mileage. He worked out with CrossFit in the offseason. With this being his senior year and him wanting to run at the next level that drove his focus more.’’
Howell teamed with Zach Tanzillo, Caden Foos and Jared Lee to qualify for state in the 3200 meter relay last spring in track and field.
Howell is on the starting line with Pickerington North’s Zach Zimmerman, Watkins Memorial’s Andrew Jordan and Rocky River’s Justin Reynolds.
Tiffin Columbian runners Brandon Gibson and Tyler Lewis, from the Northern Ohio League, are also near Howell.
“We’re staying with the same game plan,’’ Karhnem said of Howell. “We want him to stay healthy. We’ll check out the course. A lot of the competitor he has run against.’’
Howell is looking for all-Ohio honors.
“I want to be in the Top-25 and top-16 makes the podium,’’ he said.
Lancaster’s Adam Wise ran a 15:52.68 to earn the 25th spot in last season’s Division I race.
Miller is making her second state appearance in the last three years.
She earned all-Ohio honors as a freshman, running a 19:17.90 to finish 14th overall in Division III.
This season, Miller won the FC (19.50) and District 1 (20.15.59) races.
She placed ninth overall in the regional race at 20:10.09.
“Amanda has been on fire for the last month during her speed workouts,’’ Western coach Brad Perkins said. “The way she has been running and working it was just getting her to believe that she was going to be Columbus bound.”
She is with Cincinnati Mariemont’s Jennifer Saxton and Covington’s Anna Dunn and Carly Shell in the starting line assignment.
