The aim of the present study was to investigate the psychological profile of the 2023 Hungarian National Distance Running Team in terms of personality traits, motivational styles, and competitive anxiety and to explore specific psychosocial factors that characterize the athletes’ mental preparation. The 16 international-level competitors were assessed using validated questionnaires in Hungarian (Big Five Inventory, the revised Sport Motivation Scale, and Competitive State Anxiety Inventory-2), and university students competing at professional and semiprofessional levels served as the control group. Results indicated that elite distance runners were primarily intrinsically motivated. Their psychological profile appeared similar to profiles found among athletes in the control group. Significant differences were found in traits, such as openness, conscientiousness, and motivation. Neuroticism was positively associated with athletes’ cognitive and somatic anxiety, with self-confidence providing a protective role. Working with a sports psychologist appeared to have no significant measurable effect on athletes precompetition anxiety. Specific personality traits and motivational structures are essential for elite sporting performance. Further research is needed to better understand and determine the specific components of mental preparation.
