The Top of Utah Marathon course starts at Hardware Ranch Wildlife Management Area, and travels down Blacksmith Fork Canyon and on into downtown Logan. The course drops nearly 1100 feet over the 26 miles. Most of the downhill is a manageable 1-2% grade.
Since the marathon course starts above 5500 feet, the elevation may adversely affect runners - especially those not acclimated. For well acclimated runners, it can be a great PR or BQ course.
