This study explores grassroots coaches’ (GCs’) perceptions of the content of a one-day coach education workshop, the programme’s applicability, their use of the content, and the perceived barriers to implementing the programme in their coaching practice. One hundred and thirteen GCs completed follow-up questionnaires, while 12 of them were also interviewed. Descriptive statistics and qualitative analyses were conducted. The quantitative results indicate that the GCs were mainly positive about the programme content and found it easy to apply and adapt to. However, few GCs seemed to apply the programme principles to a great extent. The qualitative results illustrate that the GCs reported barriers that seem to relate to programme characteristics, in particular a lack of follow-up; individual factors, such as a lack of time; and organizational factors, like the lack of a shared understanding of the programme with their co-coaches, and lack of support from club officials. Thus, the findings imply that there is a need for an extended focus on organisational factors, especially support by club officials, when implementing coach education content in youth sports. Future recommendations for implementation of coach education workshops for youth grassroots coaches have been suggested, where support for the coaches is a key issue.
