I actually had a difficult time making it through this one, as I've seen the same eyes asking the same question. I couldn't have put it any better than this and I'm happy that Leon Lutz took the time to write it. And thanks to irunfar.com for publishing this. Seriously... to me, this is an astoundingly thoughtful piece.
As a father of two beautiful little boys (and husband to a pretty amazing Mom), I understand the torment in those eyes as you get ready to head out the door. It is hard to need something that appears outright to be so selfish, yet feels so important.
I one day hope that I can teach my boys why I run.
