Marathon runners know that the 26.2-mile races provide plenty of opportunities for humbling moments. For Don Wright, the first occurs when the horn goes off and he crosses the starting line. For Wright, 70, each race is another step in his battle to ward off multiple myeloma, a cancer that has no cure and often manifests itself through bone or back pain…"The weight-bearing actually helps preserve bone density," said Dr. Martha Lacy, Wright's physician at Mayo who has studied the illness for more than 15 years. "He's got lots of stamina and his attitude is amazing. He is focused on being well. He's quite a guy."
