The Equinox Marathon is one of the oldest continuously run marathons in the U.S. It has undergone several measurement efforts: from a jones counter to wheel to both high quality and low quality GPS. The issues with this course are many root-filled single track trail sections and a large amount of elevation change. There is local debate about the right way or most accurate way to measure this course as it is undergoing trail reroutes. Looking for advice and opinions on this matter. equinoxmarathon.org can give you info on the event. I can be directly reached at fsbn3@mac.com. Thanks.
