Belen sprinter Sophia Cox places top 25 at nationals
Sophia Cox took top 25 in the 400 at nationals after qualifying through USATF’s regional ladder, backed by a fundraiser that had reached $3,300.
Belen sprinter Sophia Cox finished in the top 25 in the 400 meters at the USATF National Junior Olympic Track & Field Championships in Norwalk, California. She raced in the 17-18 female age group at Falcon Stadium at Cerritos College, a venue in the Norwalk area that hosted the national meet.
Cox did not get there by invitation alone. USA Track & Field’s youth championship path runs through Association Championships and then Regional Championships, with only the top five from regionals advancing to nationals. That made Cox’s finish a marker of how far she had already moved through a crowded qualifying ladder before reaching California.
The Belen High School sprinter brought a strong résumé into the meet. Cox is a two-time New Mexico state champion in the Class 4A 400 meters, and her personal best is 55.92 seconds, a mark she posted in May. New Mexico Activities Association results also show her 400-meter prelim time at 55.95 and her finals time at 55.92, evidence that her speed held up when the pressure rose at the state level.
Local track pages have long treated Cox as one of Belen’s fastest emerging runners. Jags Elite listed her as the No. 1 freshman in Class 4A in the 100 and 200 meters and No. 2 in the 400 at Belen High School, a sign that her range was already drawing attention well before she reached nationals. A Valencia County News-Bulletin post on May 17, 2025 also identified Cox as a standout Belen athlete, and the Belen girls’ strong showing at the 2025 NMAA state meet added to the backdrop around her national appearance.
The trip also carried a real financial lift. A fundraiser titled Sophia and Tommy Cox: Local Pride at USATF Championships had raised $3,300 toward a $5,000 goal, underscoring the cost of taking a Valley athlete from Belen to a championship in California. For younger runners in Valencia County, Cox’s path shows what a national result can look like from a small local program: fast state-meet times, a club pipeline, and enough family and community backing to get through the qualifying rounds and onto the national stage.
