Ultramarathon (UM) running is a rapidly growing sport throughout the world, yet to date it has received little attention in sport psychology literature. To obtain further insight into this sport, the current study examined the training and competition experiences of UM runners. Phenomenological interviews were conducted with 26 participants ranging in age from 32 to 67 years (M = 44.1 yrs, SD = 8.1). Qualitative analysis of the interview data identified meaning units, which were grouped into major themes. A final thematic structure revealed five major themes that characterized the participant’s experience of UM running: preparation and strategy, management, discovery, personal achievement, and community. Taken together, the present results extend previous research on UM running and provide a number of suggestions for sport psychology consultants working with UM runners.
