From a Wall Street Journal online article:
Ms. O’Loughlin participates in a sport called tower running, which involves racing up skyscrapers, towers and stadium stairs. She’s ranked first in her age group nationally and 76th among women globally, according to the Towerrunning World Association. “I never take an elevator up a building unless it’s the only way up,” says Ms. O’Loughlin, who lives in a retirement community in Denton, Texas.
Ms. O’Loughlin runs the 20 floors of a building at Texas Woman’s University in Denton on Mondays and Thursdays. There are 20 steps a floor and she usually runs three to four reps. Leading up to a race, she will increase to five reps, and she descends backward, holding the railing. “It saves your knees,” she says. “I realize I’m 75, not 20.”
When Marsha O’Loughlin goes to Paris this March, she won’t be snapping photos of the Eiffel Tower. She’ll be too busy running up its stairs.
The 75-year-old is one of 131 participants who plan to compete in the 2020 Verticale de la Tour Eiffel, a race up 665 of the tower’s stairs.
