Fellow sophomores Rachel Englund and Nikki Shrader, as well as seniors Barkley Castro and Darian Wikel and freshman Alyssa Rittinger join McMillion in the team's top six.
At Hurricane, Coach Jason Henley, who replaced long-time Coach Bill Posey, said he hopes to return to state after last year's third-place showing, but the Redskins will have to replace graduated seniors Emily Schwendiman, Natalie Schwendiman and Baylee Summers.
"We basically just reload," Henley said of fourth-ranked Hurricane. "We had a strong team last year that was basically undefeated through the regular season except for one out-of-state meet, and we won conference and regionals."
Senior Tori Dent returns to lead the team after sitting out the track season. Seniors Ally Lawhon, Krissy Rich, junior Joie Johnston, sophomore Abbie Short and freshmen Anna Gordon and Taylor Walroth will also look to lift the Redskins statebound.
Meanwhile, eighth-ranked Midland will also look to contend with Hurricane and Winfield.
"This team has potential," Knights Coach Chris Parsons said of his 29-member squad. "They're going to have to work hard to get to state. We're in a tough region. You've got Winfield, who's going to be very good this year. Hurricane's always good. Right now, if you're looking on paper, those are the top two teams in our region."
Midland graduated four members from its team that finished fifth at the state championship meet last season. Senior Shelby Nelson, junior Jenna Marsh and sophomore Hannah Morgan return from that squad.
In addition, sophomores Zoey Chapman, Audreanna Lewis and junior Kendell McNeely will be top contributors. Freshmen Katie Riedel and Allison Short represent the No. 1 and No. 2 Cabell County middle school runners from last year. Fellow freshman Lindsey Cummings will also contribute, Parsons said.
Within the region, Huntington, Lincoln County, Logan, Nitro, Point Pleasant, St. Albans and Spring Valley will also compete.
Across the state, Parsons and Henley said defending champ Morgantown and runner-up University, along with Jefferson, will be the teams to beat this season.
Class AAA Region III
Defending regional champ Capital returns with one of the state's top runners in junior Peyton Panger, who placed eighth at last year's state meet.
"Peyton's in good condition," Capital Coach Jared Smith said. "She's had a good summer in training. She seems like she's got more intensity now."
Sophomores Riley Simmerman and Mary Keeton Lane will look to help 10th-ranked Capital remain among regional favorites. Five freshmen will join the three returners.
"It's sort of a rebuilding thing, but with Peyton and those two other girls, I think they're going to be really good," Smith said. "We're hoping for a repeat, but it's going to be tough."
George Washington and Greenbrier East figure to be Capital's top regional competition.
Adrienne Arnold represents the top Patriots returner.
"She's our senior captain, so we're expecting big things out of her," GW Coach Nick Bias said.
Seniors Rowan Maher and Olivia Lim also return in hopes of a regional crown.
Additional teams competing in the region include Oak Hill, Princeton, Ripley, Riverside, Shady Spring, South Charleston and Woodrow Wilson.
