I know this is a stretch, but a guy who goes 3:50 & 7:30 indoors and is now in 26:3X shape certainly is ready for a phenomenal 5000, or will be in a few weeks. He's a class ahead of other americans who have done 12:55-12:56, probably at least ready for 12:45-12:48 right now.
By the end of summer, could he be attacking 12:40? That's right at the door.
Other than becoming a new father, and that is a factor, he seems ready to get there!
