I am an Ultrarunner

Through inclimate weather, injuries, and even hallucinations, David Johnston just keeps running. As of 2015, Johnston is the Iditarod Trail Invitational record holder for the 350-mile run from Willow to McGrath. He completed the trek in just four days, one hour, and 36 minutes.
