According to National Federation Rule, head-coverings may be worn if there is a medical/religious reason. Knowing that there is no benefit to an athlete to wear one, does an athlete have to get some kind of note from a doctor, rabbi, or imam to do so? If a note is required, where in the rulebook is it? I had an athlete at a meet yesterday get told they were being let in the race just this one time, but next week she won't be able to run without a note from her religious leader.
