Manhattan —

Angela Murdock calls herself a “track head” – someone whose life revolves around track and field. She’s been one since age 5, when she started running in potato sack races at her Catholic elementary school. As a teenager, she helped Brooklyn’s Bishop Loughlin High School win several city championships, and earned an athletic scholarship to Mount Mary College.

After college, Murdock became a track mom – shuttling her daughters to meets, setting up hurdles and timing events. But she eventually found herself reaching for the starter’s pistol.

Now Murdock, who spends up to 40 hours at the Armory Track in Washington Heights during the indoor season, has six guns. She’s started national elite and college races that have yielded four world records.

But being a starter official isn’t her main gig.

Murdock works as vice president for accounting at a hospital during the week, while caring for her husband and five daughters. Sometimes she gets tired, but she always finds the strength to offer a loud and clear, “On your marks, get set – go!”
