William Byron reaches NASCAR Cup Series championship after fitness and diet changes

William Byron, driver of the No. 24 car for Hendrick Motorsports, is one of four contenders in the NASCAR Cup Series championship this weekend at Phoenix Raceway. His entry into the Championship Four was marked by a rival's penalty that eliminated him from the playoffs. Byron has focused on fitness this season, which he says has improved his performance. He has shifted from a casual approach to a structured workout routine, including running and weightlifting, and has changed his diet, moving away from sugary breakfasts like Pop Tarts. As he prepares for the championship race, Byron emphasizes the importance of mental health and sleep in his routine. He aims to maintain a disciplined diet, especially on race weekends, to enhance his performance on the track.
