Clarence DeMar Marathon

Course highlights

Marathon

The Clarence DeMar Marathon is a tremendously well-organized, welcoming race held during early New England foliage season. The 26.2-mile course is USATF-certified and a Boston qualifier. At the DeMar, we give our runners a world-class experience as we celebrate each and every cross of the finish line.

The Full Marathon begins in Gilsum, N.H. The Half Marathon begins at the Surry Recreational Dam in Surry, N.H. The Super Seniors and Kids’ Marathons begin 1.2 miles from the finish line.

The course then follows the route past Bretwood Golf Course and into Keene. You finish at the historic finish line on Appian Way at Keene State College, just yards from where Clarence DeMar trained college cross-country and track runners.

Half Marathon

So you’re only half-crazy? Then the DeMar Half Marathon is for you! The 13.1-mile course winds through exquisite scenery of early foliage season. All DeMar half-marathoners enjoy a world-class running experience, along with the support and encouragement of 300+ volunteers.

The Half Marathon begins at the Surry Recreational Dam in Surry, N.H. at 8 a.m. in September. From the start line, you follow the route through Surry and into Keene.

Portapotties are available every six miles on the course and at the finish. Staffed water stations are available approximately every 1.5 miles.

You finish at the historic finish line on Appian Way at Keene State College, just steps from where Clarence DeMar trained college cross-country and track runners.
