Running Out of Excuses

"Wow. So are you running enough these days that you could have done a half-marathon this weekend?'

"Well, yes and no. If I hadn't had the injury I was intending to do it, yes. I am not running that kind of distance right now, no. But truly, you could train for a half-marathon in about eight weeks"

"Really?"

"Yes."

"Ah. But I am wondering. This training to run a half-marathon? Does it entail having to get your butt off the couch? That might get in the way for me."
