Katherine Legge is no stranger to endurance events, having raced in the 24 Hours of Le Mans, 12 Hours of Sebring, and Rolex 24. Her experience will be crucial in tackling the Indy-Charlotte double.
Legge's unique challenge comes from switching between IndyCar and NASCAR, two vastly different sports with distinct gear changes and racing styles.
Only five drivers have attempted the double since its inception in 1974, with Tony Stewart holding the record for completing all 1,100 miles.
The historic Indy 500 was always held on Memorial Day until 1974, when it was moved to a fixed date. This allowed some drivers to compete in both events before.
Legge is not only the first woman to attempt the double but also one of the oldest drivers to do so at age 45.
She has sought advice from Kyle Larson and Kurt Busch, who have successfully completed the double in previous years.
Legge's preparation involves watching videos of previous Indy 500s and Coca-Cola 600s, studying data, and focusing on building muscle.
The logistics of her attempt are being handled by a team while Legge focuses on physical and mental preparation.
With only five drivers having succeeded since 1974, Legge faces an unprecedented challenge in the world of motorsports.
The Indy-Charlotte double is a grueling test of endurance, requiring mental toughness as much as physical strength.
