Through studying an ongoing mainstreaming of parasports within the Swedish sports system, this study contributes with implications for practice, as well as filling the scholarly gap in how community sports clubs are doing inclusion of people with disabilities in the daily sports practice. Through thematic analysis, semi-structured interviews with 18 club representatives were coded. This was followed by analysis with frame factor theory, which makes visible how conditions within–and around–sports clubs shape the doing of inclusion of people with disabilities in the mainstream environment. The results show how various limiting conditions, such as lacking information regarding mainstreaming, create issues in clubs’ doing of inclusion. Leaders’ individual conditions and actions are highlighted as a key feature in this doing, with individual approaches seen to create challenges in what kind of inclusion athletes meet in their daily sports practices, currently and in the future. Lastly, ableist conditions of sports are discussed, and questions are raised regarding if mainstreaming actually is an efficient means for achieving inclusion of people with disabilities.
