Welcome to the Runner's World Show, where each week we entertain you, inspire you, and inform you about all things running.

I'm David Willey, editor-in-chief of Runner's World.

This week, we are rebroadcasting one of our favorite episodes from last summer.

Our producer, Sylvia Ryerson's look into how running intersects with driving.

Really, really fast driving.

Thanks for joining us.

Here at Runner's World, we love learning about how running enhances people's lives,

about how being a strong runner can help you be better at just about anything

else. We especially love hearing about the vital role running plays in people's professions,

because some jobs, of course, require physical fitness. But it's not always the obvious occupations

that spring to mind, occupations like race car driver.

Our producer, Sylvia Ryerson, along with web producer Robert Reese, traveled to the Pocono Raceway in Long Pond, Pennsylvania to run and talk with NASCAR drivers and members of their

teams about why it helps to be fit and quick on your feet if you want to go fast on four wheels.

So you guys run together quite a bit?

We have this season because he's been training for his 5K,

so I kind of ran with him a little bit,

but he's been running a lot more than me,

so Trevor's in peak run fitness at the moment. Nice. Landon took it pretty hard on me at Bristol, though. That's why I haven't run with him as much, because I had a little progression run, and he put a hurting on me, so I was like, I didn't enjoy that at all. I think I'll just stick to my aerobic face training and let Landigo hurt himself. It was ridiculous.

That's Robert, running around the infield of the 2.5-mile Pocono Raceway,

known as the tricky triangle, with NASCAR drivers Landon Castle and Trevor Bain.

They're both full-time drivers in the Sprint Cup series, the top division of NASCAR, the best of the best. They're also both runners, part of a new generation of professional drivers who are using

running to give them an edge.
