In 2017, world-class ultrarunner Hillary Allen was at the top of her sport--and it felt like she was running on top of the world as she competed in Norway's Tromso Skyrace. Allen was nearly halfway through the 50-kilometer race when she fell 150 feet off an exposed ridge, fracturing her back and breaking multiple ribs, both feet, and both of her lower arms. Beginning with the dramatic story of her accident and rescue, Out and Back: A Runner's Story of Survival Against All Odds recounts Allen's fight to return to the life she loves. With vulnerability that reveals remarkable strength and introspection that yields wisdom, Allen shares the story of her recovery both physically and mentally, and hard-earned knowledge that the path forward is not always linear, that healing takes time, and that the process of rediscovery is ongoing as she learns what it takes to survive--and thrive. Out and Back is an inspiration to anyone who knows what it means to reclaim and rebuild your life, one day and one step at a time.
