In this second part of his powerful blog series, Autistic ultrarunner and UESCA-certified coach Ishmael Burdeau shares how embracing his diagnosis transformed not only his understanding of himself but also his entire approach to sport.

His story is a moving reminder that finding the right fit can turn difference into a defining advantage.
