At the age of 50, mother of three, Molly Sheridan, puts on a pair of running shoes, soul searching for a way to transition into the second half of her life. Within a few weeks and a trip to the doctor, Molly is told she is too old, too tall, and too un-athletic to begin running. Following her own council and heart's desire, she embarks on her secret dream, to run long distances. This thought provoking, sometimes humorous account follows Molly's journey, beyond motherhood and age barriers, to novice runner, onward to extreme adventure tackling the toughest footraces on the planet and becoming the first American woman to attempt and complete 138 miles in the Himalayas. Molly's message is simple: life begins at 50.
