Advocacy in Athletics
C.C. Tellez 2023 Mexico Gay Games Gold Medal
Téllez's advocacy has led to the adoption of nonbinary race inclusion and registration with equal prizes in events such as the Philadelphia Distance Run (PDR). After the groundbreaking PDR nonbinary race inclusion, the Blue Cross Broad Street Run, the Philadelphia Marathon, and all seven World Major Marathons, including Berlin, Boston, Chicago, London, New York, Tokyo and Sydney followed shortly afterward.[16][17][18][19]
The DVLF praised Téllez's transformative efforts, stating:
"C.C. has been instrumental in promoting LGBTQ+ acceptance in running. Her efforts toward non-binary inclusion resulted in races adopting more inclusive policies, including the Philadelphia Distance Run, the first public race to offer non-binary race registrations with equal prizes. Since helping to generate this change, in 2022, the Blue Cross Broad Street Run and the Philadelphia Marathon, along with five of the six World Major Marathons—including Boston and Berlin—have adopted the policy."[21][22]
