A legend in the making 😳 South Dakota’s Brianna Reilly takes home the win in the New Balance Nationals Indoor middle school girls mile championship, breaking the tape in 4:52.04. That time would’ve been good enough to win the freshman girls section by nearly two seconds. Reilly made a name for herself on the cross country course last fall, as the 8th-grader from Harrisburg finished 9th at NXN. #NBNationals
