A 34-year old woman sought nutritional guidance at our clinic after what she described as a recent episode of dehydration. Medical records were obtained, and the following clinical picture emerged. A month earlier, the patient had participated in a half-marathon running event (21 km, 13.1 miles) conducted in extreme heat (33 deg C, 100 deg F). Her training had been limited to 1 to 2 days per week on a treadmill, not exceeding 15 km (9 miles) weekly, in air conditioning. Beginning 3 days before the race, she experienced symptoms of viral illness, including nausea and diarrhea, but ran the race regardless.
