Nevada Mareno of Leesville Road High School rose to fame last indoor track season when she out-kicked Ryen Frazier for the New Balance Nationals Indoor mile title. After her first summer of serious training, the junior -- who was a consistent 18-minute 5K runner one year ago -- has developed into a national title contender.
