Much of the research on self-talk in sport has focused on the effects of assigned self-talk (e.g., instructional self-talk, motivational self-talk) on the performance of laboratory tasks and/or tasks of short duration (Hatzigeorgiadis, Zourbanos, Galanis, & Theodorakis, 2011; Tod, Hardy, & Oliver, 2011). The purpose of this study was to explore more fully the self-talk of athletes involved in competition over an extended period of time. Marathon runners (N = 483) were surveyed. The majority (88%) of runners, those who indicated that they use self-talk during marathons, completed open-ended items describing their self-talk while competing. Runners reported using a rich variety of motivational self-talk as well as spiritual self-talk and mantras, types of self-talk less widely studied in the literature. Given the findings of this research, future studies exploring self-talk use during competition in sporting events of long duration seems warranted.
