Sara Hall is the definition of a mother-runner. She’s the only athlete to snag 10 U.S. Championship titles across distances from the mile all the way to the marathon, and she’s currently training for the California International Marathon to go after another. When she’s not chasing PRs, she’s raising four daughters and planning a tour for her new book For The Love of the Grind coming this spring, a candid look at how she’s navigated record-breaking running while balancing life as a mom.
