22nd Annual Run Through Time Trail Marathon and Half Marathon

Past Results

There have been several different versions of both the marathon and half marathon courses throughout the years, along with varying course conditions (especially with varying amounts of snow on the marathon course). The original courses were mainly dirt roads/jeep roads, which switched over to more trails in 2011. That being said, below are the five fastest M/F times that have been run in the marathon and half marathon on the trail versions of the courses.
