Ryleigh Marshall got her start in gymnastics at 18 month sold in a mommy and me class. Once Ryleigh was old enough to take classes on her own, she was invited to pre-team at the age of four. By the age of five, Ryleigh began competing as a level 1 with Reflex Gymnastics.

In the fall of 2018, Ryleigh began training at Orlando Metro Gymnastics and competed level 1 during the fall of 2018. Ryleigh competed level 3 during the 2019-2020 season and finished fourth on vault at the Florida State Championships.

Currently, Ryleigh trains 16 hours per week under coaches Emanual Chiclana and Julimar Torres-Ruiz at Orlando Metro Gymnastics and will compete level 4 during the 2020-2021 season. Soon, Ryleigh hopes to get her back handspring on beam, her layout on floor, and a perfect cast handstand on bars. In the future, Ryleigh's goal is to compete for LSU.
