Ultra-running legend Helen Klein turned 100 on November 27, 2022. A force of nature, she believes anything is possible if it is within your grasp. Few people have grasped as many accolades as she has. Over the course of her remarkable career, Klein amassed 75 national and world records, completed 90 marathons and 143 ultramarathons; and at age 66, was one of the first athletes to complete the Grand Slam of Ultrarunning which consists of four of the most demanding 100-mile trail races in the United States. At 72, she completed a 145-mile race in the Sahara Desert in Morocco. Just weeks later, she finished the punishing 370-mile Echo-Challenge in Utah. She also holds the marathon world record for women aged 80 and over in 4:31:32, which she set at the 2002 California International Marathon. Five years later she shattered the 85 and over record at the same race.
