Background and Study Aim. The achievement theory points to two motivational orientations that represent different views on an individual's perception of success. In sports, these aspects are closely associated with various individual characteristics and athletic achievements. The aim of the study is to determine the relationship between personality traits and aspects of goal orientation among long-distance and mountain runners of both genders. Material and Methods. The study involved 9 women aged 26 to 34 and 13 men aged 26 to 38 who were members of the national long-distance and mountain running teams (medallists at the Polish and European Championships in their disciplines). Among the participants there were graduate students. The Polish adaptation of Costa and McCrae’s NEO Five-Factor Inventory questionnaire was used to examine the level of personality traits. The level of goal orientation dimensions was determined using the Polish adaptation of the Task and Ego Orientation in Sport Questionnaire. Statistical analysis was performed using Statistica 13 software. Results. In the studied group of male athletic competitors, three significant relationships were observed: a negative correlation between ego orientation and both neuroticism and openness to experience; a negative correlation between the overall level of goal orientation and neuroticism. These results are explained by the relationship that occurs between emotional balance and resilience to criticism and the desire to compare oneself to others and the tendency to demonstrate superior skills in front of others. Conclusions. The findings underscore the importance of considering individual characteristics in athletic competition. Emphasis is placed on the necessity of assessing personality traits and goal orientation dimensions among student and competitive long-distance and mountain runners of both genders. Additionally, the significance of these factors in predicting sporting achievement is highlighted, suggesting avenues for further research and practical application.
