Bill has got a ton of miles under his feet working on a project to run a marathon in all of the United States National Parks, and this is a great story to listen to on your next long run! When you press play, you're going to hear us talk about a bunch more, too.

-Running (obviously!) Why he loves it now, the community behind it, and more.

-Giving yourself permission to slow down.

-Different mindset shifts he's experienced at different points of his life.

-How and why his National Park project got started.
