ABSTRACT This study evaluated the International Society of Biomechanics in Sports (ISBS) women’s mentor circle programme. Forty-eight ISBS women members completed a survey that provided insight into how the circles operated, perceived benefits, and challenges to participation. Most circles met every 6–8 weeks with meetings lasting 1 to 1.5 h. However, some circles did not commence or stopped meeting before the end of the 2 years. For those who actively participated, the circles provided personal and professional benefits, which included developing a supportive network and confidence, and improved work–life balance habits. Furthermore, the programme was found to be a valuable use of their time and strengthened their sense of ISBS as a supportive community, increasing their likelihood of staying an ISBS member. Time zone conflicts, lack of a group leader, and changes in individual work or personal life commitments influenced the continuation of some circles over the 2 years. Some respondents did not participate in the circle, and the main reason was lack of knowledge of the programme. Overall, the programme was considered a worthy initiative, providing a supportive network to assist in advancing women biomechanists. Future programmes should ensure a clear alignment between member’s expectations and the outcomes of circle participation.
