of the 50 races were conventional marathon races. Since marathon races are typically held only on weekends, on the other days Karnazes (accompanied by between one and 50 runners) ran the course of a marathon in each state using the help of the race director and staff of each event to officially run the certified course, but on a different day than the "live" event. (For example, as part of the 50/50/50, Karnazes ran the official course of the Boston Marathon, but not the race itself, which is held in mid-April.) Karnazes overcame the endurance and logistical difficulties of this goal and finished the final marathon, the NYC Marathon, on the official race day in 3 hours and 30 seconds. He weighed at the start and at the end. The adventure was the primary subject of film director JB Benna's 2008 film entitled UltraMarathon Man: 50 Marathons, 50 States, 50 Days, which was the first feature film about Karnazes. The film was produced by Journeyfilm and was released in theaters in 2008. A similar project, undertaken by Sam Thompson to raise money for victims of Hurricane Katrina, was finishing as Karnazes began his project. Thompson ran 51 marathons (all 50 states and D.C.) in 50 days. Criticism Karnazes' achievements have been derided among some runners as tainted with hyperbole and that his fame is primarily due to self-promotion in the media, rather than top athletic performances. The president of the American Ultrarunning Association noted that he was "not even in the top 10" of runners. Former elite runner Weldon Johnson said "Dean's biggest accomplishment is not in running, but in marketing." Ultra-marathoner John Morelock defended Karnazes, but also said that Karnazes was "very good, not great. He's not a racer, just a very good performer." Other businesses In 1995, Karnazes founded Energy Well Natural Foods in San Francisco and he remains president of the company, now called Good Health Natural Foods. Karnazes is also a regular columnist for Men's Health. In 2011, Karnazes opened a Frozen-Yogurt shop in San Anselmo, California called U-Top It! Media appearances According to his sponsor, Karnazes has been featured on The Today Show, 60 Minutes (2009), The Late Show with David Letterman, CBS News, CNN, ESPN, The Howard Stern Show, NPR's Morning Edition, Late Night with Conan O'Brien, and the BBC. He has also appeared on the cover of Runners' World, Outside, and Wired magazines,
