Death Valley, California
By Lucy Nicholson
Park Sukhee, 46, had been running and walking for more than 35 hours when he approached the base of Mount Whitney. His friend handed him a South Korean flag and he broke into a jog and a smile. Running ahead of him to take photos, and realizing I was his only other spectator, I lowered my camera to applaud his achievement.
Park had just run 135 miles (217 km) from the lowest point in the Western Hemisphere, Death Valley, to the trailhead to Mount Whitney, climbing a total of 13,000 feet (4,000m) over the course, in temperatures that blazed to about 120 degrees Fahrenheit (around 49 degrees Celsius).
