"In her twenties, Alexandra Heminsley spent more time drinking white wine than she did in pursuit of athletic excellence. When she decided to take up running in her thirties, she had high hopes for a blissful runner's high and immediate physical transformation. After eating three slices of toast with honey and spending ninety minutes on iTunes creating the perfect playlist, she hit the streets--and failed miserably. The stories of her first runs turn the common notion that we are all "born to run" on its head--and exposes the truth about starting to run: it can be brutal. Running Like a Girl tells the story of getting beyond the brutal part, how Alexandra makes running a part of her life, and reaps the rewards: not just the obvious things, like weight loss, health, and glowing skin, but self-confidence and immeasurable daily pleasure, along with a new closeness to her father--a marathon runner--and her brother, with whom she ultimately runs her first marathon"--
