The 5-foot-3 junior won the Division AA state meet this past season with a time of 17:31.91, breaking the tape 29.35 seconds ahead of her next-closest competitor and leading the Knights to a fifth-place finish as a team. Castelli, who also earned First Team All-State honors for the O’Gorman girls soccer team this fall, was the only state runner to qualify for a national championship race after her fourth-place finish at the Nike Cross Heartland Regional Championships.
Castelli has maintained a 3.96 GPA in the classroom. She will begin her senior year of high school this fall.
Castelli’s sister, Katie, was the 2020-21 Gatorade State Girls Cross Country Player of the Year. She has volunteered locally at the St. Francis House, which works to lift people out of homelessness. She has also donated her time with Soccer Stars, an adaptive program for children with special needs.
