She's the First Athlete Ever to Win a Marathon Grand Slam Outside of her Paralympics and World Championships success, Tatyana — who's long been called "The Beast" because of her ability to climb hills — is an accomplished marathoner. In 2013, she became the first athlete to ever achieve a marathon Grand Slam, winning the wheelchair divisions of the Boston, London, Chicago, and New York marathons in a single year. She went on to complete the Grand Slam in four consecutive years. Image Source: Getty / Elsa / Staff
