Who are the main characters in 'Heart of Champions A True Story'?
Without having read the story, it's difficult to determine the main characters precisely. However, given the title, it could be about a team of individuals who are at the center of a remarkable journey. They could be players on a sports team, each with their own backstories and dreams. There might be a key leader among them, perhaps a coach or a veteran player who instills the 'heart of champions' in the rest of the group. Or it could be about an individual athlete who has a support system of friends, family, and trainers that play important roles in their story of achieving great things with their 'heart of champions'.
I'm not sure as I don't know the details of the story. But they could be athletes, coaches, or anyone involved in a competitive pursuit.
