With the 2024 Olympics in Paris, a lot of attention has been put on elite sports. Elite sports concern a limited set of top athletes from around the globe who have been training for many years, from nutrition to mental preparation, to achieve the best possible performance during the competition. Many researchers ---including the co-authors of this paper --- have been involved in helping athletes reach their best level of performance by carrying out research in close collaboration with Olympic federations, analysts, and coaches. This led to a deeper understanding of needs, applying or developing new data capturing, analysis and presentation methods. However, this work remained only in the perimeter of high-performance sports while the benefits of the work can reach beyond elite sports to casual activities, health, or recovery. In this workshop paper, we discuss some of the challenges we envision and face when applying what we know about supporting elite sports. We end with specific questions we would like to discuss in the workshop.
