American Suunto athlete Liz Canty has become the poster-child of grit. Her path to ultrarunning is unique: Her background is in rugby as she played collegiately at the University of Massachusetts.

Needless to say, Liz is no stranger to hard work and dedication. After pacing a friend during an ultramarathon, she decided it was something she would like to try. She has since embraced the sport of ultrarunning, and since 2015 has powered through three 100-mile ultramarathons. Her short time in ultrarunning has already changed her life and taught her lifelong lessons.

“I’m realizing that the most I learn after each long-distance race is how to be a kinder and more flexible person. I bring too much of my Type A personality to these events and have to keep improving my ability to compromise, goal-set on the fly, and most of all, smile,” says Liz.
