The Medford Historical Society & Museum invites you to the talk “Defining Moments” with Dave McGillivray, race director of the B.A.A. Boston Marathon and motivational speaker. Everyone has a story to tell. For McGillivray, a Medford High graduate, it was his strong desire to be an athlete that led him to run across the country in 1978 at age 23. That 80-day trek across the U.S. led to a life of pushing himself both mentally and physically. He addresses audiences with a motivational account that is not about running, but rather about what’s possible if you believe in yourself and your own ability to do the seemingly insurmountable. Come hear Dave translate his extraordinary life journeys and athletic achievements into life lessons that leave each audience wanting more.
