DENVER, CO - SEPTEMBER 21: Brie Oakley of Grandview looks like the next great Colorado HS runner gets in practice September 21, 2016 at Grand View high school. She recently ran the best time in the nation for a high schooler this year and she did it at altitude. In the process she broke the record at the Liberty Bell XC meet, one of Colorado's biggest XC meets, taking the record from another superstar runner.
