Alicia and Helios' baskets against leukemia: "When I train I am accelerating the treatment". Both receive cancer treatment at the La Paz University Hospital in Madrid.

The Accelerator is a non-pharmacological therapy unit created by the Unoentrecienmil Foundation. It is designed to allow the practice of precision physical exercise in children with cancer and promote research in this area. The training is always individualized, agreed upon with the doctors and after a constant re-evaluation to adapt to how the patient is physically.
