61 | Tish Hamilton

If Tish Hamilton is being honest, she doesn't consider herself a pioneer in women's running. She looks at titans of the sport like Kathrine Switzer and activists like Alison Mariella Desir—"They're legit," Hamilton says. But Hamilton's work in the sport—as the first female executive editor of Runner's World magazine—is nothing to sneeze at. Hamilton calls the marriage of her two passions—running and journalism—a privilege. She helped usher in the second running boom, one driven largely by women, one step behind the helm of the go-to magazine for runners. The mission was to broaden the coverage of the sport—from elites to weekend warriors doing incredible work—and with that, bring in a more varied audience, including women.
