This week track and field athletes from all over the world are gathering to compete in the World Championships, an event second only to the Olympics in its level of prestige. Two of the competitors, South African Caster Semenya and Indian Dutee Chand, will represent their countries while on a quest for gold and glory that started last summer in Rio.
