Early career Slagle began racing at seven years old after her father bought her a
quarter midget. She won the
Dixie Motor Speedway Female Driver of the Year award three times, from 2007 to 2009, where she also won Rookie of the Year in 2007. She won the
Owosso Speedway track championship in 2011, while also winning the "Got Game" award. Slagle moved up to the
Champion Racing Association in 2014, posting her best finish of 14th at
Salem Speedway that year, and would get that same finish the following year at
Springport Mid-Michigan Speedway. She would put her racing career on hold in 2016 after the money for the tour became more expensive. Slagle made her return in 2017, starting 20th and finishing 16th at
Owosso Speedway. Slagle moved south in 2018, questioning if she would ever race in a late model again. She got the opportunity with
Cook-Finley Racing, and would drive part-time late model races in the Southeast Limited Late Model Series, and would drive in the
NASCAR Advance Auto Parts Weekly Series from 2019 to 2020.
