Boeder continues to be an avid runner and race organizer. He has a PhD in history. After teaching for a number of years in universities in Africa and the United States, he now works for the Us Army at Ft. Bragg, North Carolina. "A well written, quick moving adventure tale which combines both the romance and the gritty realism of ultrarunning; filled with practical knowledge for anyone attempting a trail 100 and excellent for non-runners seeking a glimpse of the ultra world".
