This past June, 72-year-old Wally Hesseltine ran the Western States 100-Mile Endurance Run. He was set to be the race’s oldest finisher ever since its start in 1974. “Thirty Hours,” a 12-minute documentary directed by Alex Massey, showcases Hesseltine’s┬átraining leading up to the race, the race day itself and his unforgettable finish as he stumbled onto the Placer High School track with 400 meters to run and 2 minutes left on the clock.
