Athletes may submit a letter from their physician that identifies the type of impairment and how the impairment impacts the person's ability to run or take part in running events. For athletes with vision impairment, certification of legal blindness or a letter from a vision specialist that includes visual acuity and visual field testing results is sufficient.
