This article addresses race and ethnicity as social practices among young students at a Danish public sports school and explores how these practices engage with emotional well-being in the institutional context. The study is based on ethnographic fieldwork carried out in two school classes in 2012-2013 using multiple qualitative methods. Taking a phenomenological practice approach, the article addresses how racial (and ethnic) practices affect everyday school life. The analysis shows how a common-sense, habitual background of whiteness positions non-white bodies as different and 'non-belonging', thus shaping experiences of being 'out of place'. These experiences are stressful to students in the study and foster a self-awareness that restrains the body from engaging habitually in the world and that obstructs emotional well-being. The article argues that a reluctance to acknowledge social practices as racial enables everyday racism while blocking the positions available to speak out against ethnic and racial discriminatory experiences.
