This study investigated factors influencing regular group indoor cycling (GIC) participation in a sample of Black (71%) and White (29%) adults. Seventeen regular GIC participants (≥1 day/week for ≥3 consecutive months) completed surveys that examined motivations for GIC participation. Treatment Self-Regulation Questionnaire (TSRQ), Preference for and Tolerance of Intensity of Exercise Questionnaire (PRETIE-Q), and open-ended survey questions were used. TSRQ showed autonomous motivation was significantly higher than controlled (p \u3c.001) and amotivation (p \u3c .001), with no significant difference between controlled and amotivation (p = .08). There was no significant interaction between motivation and race. There were no significant differences between race groups for PRETIE-Q. Five themes emerged as reasons for GIC participation: music, physical health, social support, studio atmosphere, and enjoyment/fun. Racial differences surfaced in the themes. More research is needed to understand the role of cultural relevance as it relates to exercise motivation and regular exercise participation. This could inform strategies for promoting regular exercise in various populations
