The aim of this paper is to research a) participants' motives for joining races and walks organized for causes, and b) to what extent their decisions to take part are influenced by the way the cause is run and its accountability. A 31-question survey with answers given on the Likert scale (from 1 to 7) was shared online, drawing a response from 150 runners. The results demonstrate that the most significant motives for taking part in these events relate to personal benefit: enjoyment, physical and mental well-being and desire to socialize. Motives of an altruistic nature scored lowest: making a difference and a feeling of obligation. The results also suggested participants give significantly more importance to the information about the cause provided before the event than they do to accountability.
