The Four-Minute Mile Club

"It's not even just for me. It's for my family too. My dad calls and is like 'Are you still doing it? Are you still training for four minutes?' And I say, 'Yeah, Pa, we're doing it,'" Davis said.

A Good Kind of Hurt

On the track, where Fox yells out times and words of encouragement, the men said their coach's faith helps them believe in themselves.

"It's always been the goal where I've been, like 'I'm going to do this, and do this, and then break four minutes and that's it,'" Butler said. For the three students, running at this level has become a way of life.

"This is what we do. Running is just part of our life. I mean, we went to bed at 9:30 last night because we knew we had to get up and knew it was going to hurt," Davis said.

But it's a good kind of hurt, they said, especially when it comes to reaching their goal. And the men said it's a matter of when, not if. They plan to break four minutes at a track meet at Penn State in January.

As for what that will mean?

"You know, I've asked myself that question since I was a kid. I've practiced interviews in the shower. ... It's just going to mean everything. It's the one goal that I have that I don't know the next step after that," Butler said.

Although there may not be cameras lined up on the day the guys meet their goal, it's a day they say they've all dreamt about for years.

From there, Olympic trials may be next, Davis and Heath both said. Until then, they all face hours of training and hundreds of miles.
