Participants raise at least $1,000 each for the unique opportunity to descend the skyscraper to benefit the nearly 11,000 Special Olympians in Iowa.
"This is such an awesome event for the Special Olympics," Hatfield Clubb said shortly after planting both feet on the ground. "It's a challenge that's unique, big and scary. It's a great opportunity for us to step out and overcome our fears like this to help these athletes who overcome and face challenges every day to compete."
No stranger to climbing and rappelling, Hatfield Clubb was joined by her father, Dolph, who is a noted adventurer in his own right that at one time held the world record for the longest single-rope rappel for his descent of El Capitan in Yosemite National Park.
"We've shared some really special adventures together," she said of her relationship with her father. "So it was great to share this experience for such a great cause."
This is the third year the Iowa Special Olympics has staged the event and the second time Hatfield Clubb has participated.
