Ironstone 100K: Course marking and navigation

Ironstone 100K 'Dirty Little Secret': Course marking and navigation - 43.8 miles of the Ironstone 100K course is blazed orange.

The Ironstone 100K course is a "graduate-level" course and the majority is not flagged! Most of the course is on two longdistance trails, the Mid State Trail and the Standing Stone Trail which are marked with orange blazes. Any time the course deviates from these two trails, the race team will post signage and/or pink confidence ribbon. We highly recommend you study the maps and download the GPX file of the course from our website.
