Abstract:	Lincoln is a 50-year old runner who, over the past five years, has completed five one-half marathons and four marathons. He regularly runs six to seven days a week, totaling 30 to 50 miles per week. For his fiftieth birthday Lincoln decided to participate in the Silver Rush 50-mile run. This 50-mile out-and-back run started at an elevation of 10,000 feet in Leadville, Colorado, and ascended 7,400 feet over four peaks, with the highest pass at 12,200 feet. During the run and after the run Lincoln encounters significant musculoskeletal problems, resulting in hospitalization and treatment. This PBL problem introduces students to exercise- induced skeletal muscle pathophysiology and the resulting disturbances in homeostasis.
