The last several years have been met with increased instances of athlete activism among college athletes. Little research, though, has investigated athlete activism among white college athletes. The present study adopted an interpretive-constructivist approach to conduct semistructured interviews with 12 white college athletes engaging in racial justice activism. Interviews aimed to develop a heightened understanding of the challenges and supports they experienced in their activism. White college athletes cited several challenges to and supports for engaging in racial justice activism. Challenges included resource deficits (e.g., lack of support), intrapersonal concerns (e.g., lack of confidence), and other external threats (e.g., difficulty balancing social justice with preexisting relationships with loved ones). Supports included individual-level support (e.g., advice from others) and institutional-level support (e.g., resources from university administrators). Findings show participants experienced more challenges than supports. Further, some challenges are unique to white athletes including struggles in engaging in racial justice activism with ingroup members (i.e., other white people). Meanwhile, support from universities, mentors, and family members was important to encouraging racial justice activism among the participants. Higher education administrators, sport psychology consultants, and other sport leaders can use this information to empower white college athletes to navigate the challenges associated with engaging in racial justice activism.
