Some people set a goal to run a marathon. Gary Saxton set a goal to run a marathon after he turned 50. Not only did he run one marathon (or longer) after age 50, but he ended up running 100 of them! Some people say they don't have time to train. Gary is an inspiration; he underwent major back surgery and had a heart attack while accomplishing his goal. His book: 100 Marathons After 50 has valuable life and running lessons for everyone.
