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 Troms Skyrace. Allen was nearly halfway through the 50k race when she fell 150 feet off an exposed ridge, breaking two ribs, fracturing her back, rupturing a ligament in her foot, and breaking both wrists. Beginning with the dramatic story of her accident and rescue, Out and Back- A Runner's Story of Survival and Recovery Against All Odds recounts Allen's fight to return to the life she loves.
