Don Kern, race director of next month's Grand Rapids Marathon & Half Marathon, knows a thing or two about putting on a great race -- not only as one of the founders of this October event in GR, but also because he's an avid racer himself, here in the U.S. and abroad. Indeed, this "adventure runner" has run more than 200 marathons in each of 50 states of the U.S. twice, in 25 countries, and at the North Pole. Heather Durocher interviews Don in this episode, talking with him about his extraordinary running accomplishments as well as the upcoming Grand Rapids Marathon & Half Marathon, now in its 12th year. He is also behind the Groundhog Marathon, held each February in Grand Rapids. This race, which debuted in 2013, features a 4.4-mile loop that needs to be completed six times for a full marathon, a nod to the 1993 movie "Groundhog Day." The Grand Rapids Marathon & Half Marathon is set for Sunday, Oct. 18. This episode also includes a special race discount code for listeners.
