Big luck to my big brother who is in town for the St. Louis Marathon!

My boys and I got to go with him to the Expo today when he registered and picked up his gear.
It was really fascinating. I had no idea how…big…running is. It’s an entire industry.
And these folks are hardcore. It’s really cool, actually.
But how do these people do this? How does one run 26.2 miles? How does one train the body to endure it?
I’m thinking I will never know. But I’m awfully proud that my brother does.
