A while back I learned the story of Katherine Switzer, the first woman to enter the Boston Marathon, in 1967. She hid in the bushes and started the race in disguise.
When the race director saw what she was doing, he attacked her, trying to rip off her race number.
Now there were a lot of runners who were supportive of her. But still, deep resistance to women's athletics was a powerful force not so long ago, and is still around today.
So when a friend passed along this delightful video of the first woman to finish the absurdly difficult American Ninja Warrior obstacle course, I enjoyed it not just for the pleasure of seeing her do it. What really got to me is all the jockish men in the audience beside themselves rooting for her. Look at their faces.
