“The boys and girls ran really well,” Butte High coach Guy Wadas said. “There were several personal and season bests. The most impressive aspect of the race was how well the kids battled and actually raced the competition. It was nice watching the young guys and girls run tough after a hard opening mile. I think today will give them a lot of confidence.”
The Bulldogs will host the Butte Invitational next Thursday at Fairmont Hot Springs.
