    2014 Marathoner, Boston, MA
  • “This is a small race in a gorgeous part of New England. It is extremely well-organized, designed for runners. It is special because of the heritage and the man it honors, the volunteers and organizers LOVE their race, and it features the beauty of New Hampshire.”

    2015 Marathoner, Colorado Springs, CO
  • “As good as a small race gets. Spot-on organization with race day packet pickup and easy logistics. Indoor staging area with plenty of room to stretch and lots of bathrooms. Free parking close to the finish. Medal and shirt are first rate. My new favorite small marathon.”

    2015 Marathoner, Pittsburgh, PA
  • “The first 15-16 miles or so are absolutely beautiful New England countryside. The race is extremely well organized, and most everyone involved with the race was positive and friendly. No crazy crowds or hassles!”
