Former gymnast Mark Gibson is no stranger to extreme physical sports.
He has run the length of the Grand Canyon twice; biked across the country from Santa Cruz, California, to Ocean City, New Jersey; and run from Pittsburgh to Philadelphia in 10 days — a feat that required he run the distance of a marathon each day.
But this year, he wanted to do something a little different.
Later this month*, one day after he turns 60, Gibson will ascend the 72 steps at the Philadelphia Museum of Art nearly 900 times. The sum of recreating Rocky Balboa’s famous run over and over will be the equivalent of climbing and descending Mt. Everest, which stands more than 29,000 feet tall
