This study explores the role of running in enhancing mental health and motivation in Indonesia using a qualitative phenomenological approach. Given the limited research in the Indonesian context, this study aims to fill an empirical and theoretical gap by examining how running contributes to stress reduction, emotional well-being, and motivation among adults. A total of 20 participants aged 24–40 who had been running regularly for at least three months were selected through purposive sampling. Semi-structured interviews were conducted to collect in-depth data on psychological, motivational, and lifestyle changes resulting from running. Thematic analysis revealed four major themes: improvement of mental health through stress and anxiety reduction, enhancement of emotional balance and mood, increased motivation and self-discipline, and the importance of social support in group running activities. Participants reported feeling mentally clearer, emotionally balanced, and more motivated to sustain their fitness routines. In particular, running in groups provided strong social support and accountability, reinforcing consistency and a sense of belonging. This study contributes to the growing body of knowledge in sports psychology and guidance and counseling by highlighting the therapeutic potential of running to promote mental health and motivation in collectivist cultural settings such as Indonesia. The findings underscore the importance of integrating community-based physical activity programs into mental health promotion efforts. Future studies are recommended to explore the long-term psychological mechanisms and cultural factors that influence participation in running.
