Coaching at a national championship tournament is different to coaching across a competitive season. The team and coaches are away from their regular environment and their normal support mechanisms are distant. While much is known about stressors for coaches in high-performance sport, the current study explored how these were manifested during the intensity of a championship tournament and the coping strategies employed by one coach of a selected, intellectually disabled basketball team. This social phenomenological analysis identified four primary stressors, creating unity and development of trust, management of parents, management of inexperienced coaching/support staff, and crisis management of a critical incident. Coping strategies employed during the tournament included planning, time alone for stress-recovery management and working with a qualified expert to manage a critical incident. The temporariness of the tournament brings unique stressors for the coach and a need to manage these quickly and efficiently, especially for athletes with an intellectual disability. The coach identified that it is unlike any other type of competition, as there is absolute consumption on the tournament and a need to create a rhythm to function effectively. The need for all team members to understand their role and responsibility suggests that a collaborative approach to leadership is essential. Failure to adapt to the tournament circumstances can inhibit chances of success.
