Legge joined Michael Shank Racing in 2017 to drive an Acura NSX GT3 at the IMSA SportsCar Championship. In the 2019 24 Hours of Daytona Legge raced as part of an all-female team alongside Simona de Silvestro, Christina Nielsen and Ana Beatriz, having placed second in class the previous year. She was placed 15th in their class after Legge brushed a wall and damaged the car's suspension.
