Two case reports (attached as appendices) have been presented during this workshop. The first case report involved an endurathon staged on a hot, humid day at Fort Bragg, North Carolina. A group of 40 soldiers competed from 9 a.m. to 3 p.m. in the following seven consecutive events: an 8-km run, a 1-h road march while carrying 32 kg of equipment, a 2-h river excursion in a rubber boat, an 8-km run while wearing combat boots and full uniform, an obstacle course, a pistol marksmanship contest, and a 1.6 km team litter carry (68 kg weight). A 10-min rest period was allowed between each event for water consumption; soldiers ate a variety of snacks, but no meals were provided. Eight cases of heat illness (e.g. heat exhaustion, heat cramps, heat prostration) occurred after the fifth event. Prior to the sixth event, a carbohydrate-electrolyte solution was provided for these soldiers and no further heat illness episodes occurred. At 10 p.m., this unit was unexpectedly placed on alert and began several hours of mission preparation.
