On Wednesday, March 23 at 6 p.m. ET, FS1’s NASCAR Race Hub will present “Boundless: Betty Skelton.” Known as the “First Lady of Firsts,” Skelton raced and flew from NASCAR to NASA, and we’ll meet the team behind this inaugural episode of a series entitled “Left Behind,” telling the stories of trailblazing women in motorsports: Cindy Sisson, the CEO of GSEvents; Pam Miller, FOX and CBS Sports auto racing producer; and Lindsey Mandia, FOX Sports Vice President of Production.
