Gretsch, who was born with spina bifida, grew up swimming and competed on her high school’s swim team
She made her Paralympic debut as a winter-sport athlete, winning two gold medals in Nordic skiing at the Paralympic Winter Games PyeongChang 2018
She became involved in triathlon after her sophomore year of college, after she was encouraged to join a local paratriathlon club, Dare2tri, while at a swim practice
She especially loves the positive community aspect of triathlon, as well as being able to race outdoors
She is inspired the most by her fellow teammates because she takes motivation from seeing them work hard in practice every day
The biggest satisfaction she gets out of competing in sports is seeing her own personal growth and having the ability to push herself as hard as she can to get better
She finds satisfaction in competing in both a summer and winter sport because she is always in a racing season, so it forces her to maintain a competitive mindset all year
In 2014, Gretsch was named the USA Triathlon Female Paratriathlete of the Year, and in 2015 she was nominated for an ESPY for Best Female Athlete with a Disability
She became a Paratriathlon Gold Medalist at the 2020 Tokyo Paralympic Games and is a three-time World Paratriathlon World Champion, earning the title in 2014, 2015 and 2016
