She described the experience as an "indescribable energy" that is hard to explain to others."It chokes me up every year. The first time I was there was actually in 2006. I was in the stands in turn one, and I remember just thinking, like, you can't experience this anywhere else, and you can't explain to anybody what this feeling is. And then standing on the grid for the first time and experiencing it, I was like, don't let it in. Put your blinkers on; don't let it in. You've got a race to run; don't focus on it," she said in the latest episode of the iHeart Radio Podcast, Throttle Therapy."But like the hairs on your arms stand up, and it's this energy, and it's an indescribable energy, and it's so bizarre to me even now, and I love it," she added.Legge first experienced this vulnerable moment in 2006 as a spectator, then on the starting grid, where she had to mentally block out the emotion to stay focused on racing.
