Toshiko d'Elia, the first female in the world to run a sub-three-hour marathon at age 50, took up running at the age of 40 to become a better mountain climber. In 1975, d'Elia started going into Manhattan to race with New York Road Runners, the only races in the area. She made friends with Nina Kuscisk, Fred Lebow, Ted Corbitt, and Kathrine Switzer, and was recruited to run with a female elite team, Atalanta, coached by Bob Glover. She was unstoppable and was given the nickname Seabiscuit after the horse that would never quit. By 1977, she was running 90 miles a week and winning long-distance races as well as sprinting events in 40-years-and-over competition. Despite having open-heart surgery when she was 78, d'Elia kept setting age-group records until December 2014, when she was diagnosed with brain cancer. She passed away peacefully surrounded by family at age 84. NOTE: This interview with Toshi and her daughter Erica was recorded by phone in 2013, a year before she passed away.
