Course Description

Each of the six loops of the Groundhog Day Marathon course has about 50 feet of elevation difference between the high and low points. As the description of the course from the race website states, in the event that there is snow on the course, it will not be cleared. Approximately a mile of the course is on crushed limestone (almost 2/10ths of a mile per loop).

Note that the PR Score and Course Score do not take into account if the course is covered with snow or ice.
