Follow the unlikely journey of former Major League Baseball player Eric Byrnes from the diamond to the rough trails of the 2016 Western States 100 Mile Endurance Run. Byrnes attempts to become the first former mainstream professional athlete to complete the grueling 100 mile course which navigates 19,000 feet of elevation gain and 23,000 feet of descent across the Sierra Nevada mountain range. Byrnes relies on his crew of family and friends, including former professional cyclist Lance Armstrong, to help him through the arduous process which challenges both his physical and psychological limits.
