Olympian Noah Lyles is ready to defend his world champion title tonight

Noah Lyles will be defending his title as the reigning world champion tonight at the World Athletics Championships. The sprinter faced heartbreak in the 2021 Olympics where he took home the bronze medal in the 200m, his signature race. Lyles said this year is completely different. The 25-year-old has also been very open with his mental health challenges and struggles to not be defined by winning or losing.
