Keira D'Amato had a promising future in running in high school and college, before stepping away for 8-years. When she returned to running, professional trajectory was not on her radar. She found new motivations and identity with running being part of her story, which lead to breaking American Records in the Full and Half Marathon. Her book, "Don't Call It A Comeback," is a great example of how success and fulfillment comes in many paths.
