Possibly the most recognizable of all ultrarunners, Dean Karnazes is a California-based athlete, author and speaker who has recently released A Runner’s High: My Life in Motion, an excellent read full of stories, humor, and reflection. The book discusses the Western States Endurance Run (WSER), a prestigious 100-miler that happens this Saturday, June 26. Dean wrote the foreword for Travis’ 2015 book, The Ultra Mindset. Join Dean and his son, Nicholas, as they talk with Travis and Mace about WSER, international ambassadorial runs, the intersection of family and endurance racing, and more.
