How do you break your arm running? It's as easy as falling down: You try breaking the impact and the impact breaks you instead.

I tried running it off, like guys claim they did in the olden days. You've heard them: "Yep, finished a marathon with two broken legs." "That's nothing. I did an Iron Man with all my bones broken and organs punctured." "You call that tough? I did an ultra across Antarctica with everything amputated below my neck, hopping on my tongue." After a half-mile I conceded I was a weenie and turned back. I mulled asking the cook at the nearby China Palace Buffet to use his cleaver on my right elbow, but I'd have to explain to him what happened, which involved a humiliation factor. "Would you believe I was passing El Guerrouj when I tripped on his heels?" "No." "I was sprinting for the world record when a lapped Kenyan veered in front of me?" "No." "I was trying to stay upright but couldn't?" "Yup." I walked three miles home, then my wife drove me to the hospital. X- rated x-rays involved radiologists wrenching my throbbing limb like a pretzel. "You broke your elbow," the doctor diagnosed. "Ow," I answered. "We'll splint it." "Yow," I replied. Then the morphine kicked in. The good news: the farce doesn't need a cast. It's just me, with a right arm that can type but not lift a camera, and a body confined to exercise on a stationary bike. "No running?" "Too jarring. It's for your own good," said the doctor. "It's more jarring to not be running." "Your real problem is your brain is broken. We see it in runners all the time." MR
