Race Information

“The Mac” is one of the oldest ultrarunning races in Oregon. A true old-school gem, it is run primarily in Oregon State University’s McDonald Forest with a short section run on Starker Forest’s “hobbit trails.” Experience the smooth lovingly-maintained singletrack trails along with the “magic of the maze” where time passes but miles do not. The race boasts one of the sweetest finishes of any race, a pine needle-cushioned downhill trail.

The forest is in full bloom in early May; the dogwoods are glowing and the delicate calypso orchids dot the undergrowth. There are scenic views of the Cascades, the Coast Range, and Soap Creek Valley.
