Peter Sagal on his unexpected journey to repeat marathoner

You don’t have to wait (wait) for Saturday to listen to Peter Sagal!

Sagal, the host of NPR’s news quiz Wait Wait ... Don’t Tell Me!, has been a regular columnist for Runner's World magazine (where we first met him, actually) and just released a book, The Incomplete Book of Running.

But if you’re not a runner, don’t just click off this page!

Sagal didn’t expect himself to be a runner, let alone a marathoner, years ago, he told All Things Considered’s Ari Shapiro.

Yet here he is now, expounding on the sport in an interview you can listen to below or that you can preview on NPR’s website.
