Greg Kalkwarf is the author of “Was That Thunder? More Than a Boston Marathon Bombing Story.” A Nebraska native who currently lives in Colorado, Kalkwarf has completed 10 marathons, including the 2013 Boston Marathon when two terrorists exploded bombs near the finish line, killing three people and injuring more than 250 others. In a 13-month period leading up to the bombing, Kalkwarf experienced a raging forest fire near his family’s mountain home, the tragic death of a family member, the happy birth of a baby girl, and a crosswalk collision with a taxi cab. His book, available on Amazon, illustrates goal-setting, trying new challenges, determination, self-belief, and overcoming adversity.
