Yeah, I saw that thread.  I love /r/running so I don't speak my mind as much as I want to, but it's just god damn self control.  There are certain runs, that yes, I eat pretty much whatever I want after.  Marathons, and toward the end of marathon training mileage I'll eat more.  But certainly not enough to put on any weight, LOL.  I run with a large group, and it breaks my heart when the slower pace groups will go out and just go hog wild with beer, pizza, and fried shit after like 4-5 miles' worth of speed work or a 10 mile easy run.  And then they go around complaining how slow they are due to their weight.  Well, no shit.  It drives me insane.  I'll say it 1000 times until I'm blue in the face, but you can't outrun a bad diet, but it just doesn't sink in.  Running is not a ticket to making your life an all-you-can-eat buffet.
