Ever since he turned fifty, Mark Gibson challenges himself to do one crazy thing every year. He has run from Pittsburg to Philadelphia and rode a skateboard from Washington, D.C. to Ottawa Canada. Now, at sixty years old, he’s tackling what he calls the Rocky Mountain Everest Challenge. Where he attempts to run the equivalent from sea level to the top of Mt. Everest and then back down to sea level again on the famous Rocky steps at the Philadelphia Art Museum. That’s up and down the stairs 880 times. He’s doing the challenge to raise money for Alex’s Lemonade Stand to help the fight against childhood cancer.
