Sean McGorty and Logan Miller went 1-2 to lead Chantilly to the team title and Allie Klimkiewicz powered the girls from Oakton to victory Wednesday at the Virginia AAA Concorde District cross-country championships in Fairfax Station.

McGorty, who has been simply untouchable this season, tied the sixth-fastest time ever at Burke Lake Park. The senior All-Met blasted away from the starting line and finished off the 2.98-mile course in a personal-best 14 minutes 38 seconds. He was a full minute faster than teammate Miller (15:38).

“There’s no pressure from another runner in our district and really no one in our region who’s going to challenge his time, so he felt free to roll the dice and see what comes up,” Chantilly Coach Matt Gilchrist said of McGorty’s breakneck speed.

The odds of Chantilly capturing its first boys’ team title in more than 18 years were far better than just a roll of the dice. The Chargers have been superior to their local competition all season — they are one of the top 15 teams in the country — and on Wednesday they put all five scorers among the top seven to dominate Robinson, Westfield and Oakton.

The girls’ meet wasn’t the blowout affair the boys’ was. Klimkiewicz battled Robinson’s Macey Schweikert all the way to the line and needed a final burst to repeat as district champ by one second in 17:36.

Behind Klimkiewicz, the Cougars won their third straight district title over Robinson by five points. Chantilly and Centreville followed.

The boys from Chantilly hadn’t lost to a local team all season and were the overwhelming favorite headed into Wednesday’s championships. But Gilchrist made sure his team was prepared. The longtime Chargers coach had had good teams in the past that were among the favorites to win titles but they all came up short.

“We don’t take districts lightly; we’ve had our ups and downs over the years,” Gilchrist said. “As a coach, I’m trying to milk this all in because it doesn’t come around very often.”

At the AAA Liberty District championships, also Wednesday at Burke Lake Park, Stone Bridge breezed to the boys’ title and Madison won the girls’.

Madison’s Laura Sullivan won the girls’ individual championship in 19:11. The Warhawks’ Matthew Calem was the boys’ champ in 15:43.
