Are endurance motorcyclists crazy? Iron Butt riders call themselves “the world’s toughest,” so you know there’s more going on here than long hours in the saddle collecting gas receipts. Meet Rick Muhr, an overnight convert to endurance motorcycling. Muhr, a marathon running coach, was a casual sunny day rider until the tragic events of the 2013 Boston Marathon sent him on a healing journey that changed his life forever. When the road inside is even harder than the road ahead, Rick’s story shows us how enduring both makes us stronger… and that sometimes an insanely long ride is the sanest thing you can do.
