Embark on a classic Oregon trail running adventure with the McDonald Forest 50K Trail Run, celebrating its 30th annual event on May 2, 2026, in Corvallis, OR. Known affectionately as "The Mac," this revered race is a true old-school gem, challenging runners with approximately 6,400 to 6,800 feet of elevation gain across a scenic loop course. You'll navigate a captivating mix of single-track trails and logging roads through Oregon State University's McDonald Forest and Starker Forest land, including a return to McCulloch Peak, the highest point in McDonald Forest. Revel in the beauty of the forest in full bloom, with dogwoods glowing and delicate calypso orchids dotting the undergrowth, all while enjoying potential panoramic views of the Cascades, the Coast Range, and Soap Creek Valley.

Runners can anticipate a challenging yet meticulously marked course, guided by orange ribbons, flour, and signs, ensuring a navigable journey through sections like the "magic of the maze" and "hobbit trails." Typical race day conditions in early May offer highs around 66°F and lows around 42°F, with a 13% chance of precipitation, meaning you might encounter some character-building mud. Four well-stocked aid stations will support your efforts, though runners must come prepared with their own water bottle or hydration pack as the race is cupless and distances between aid can be up to 6.6 miles. Drop bag service is available for Aid Station #3 at McCulloch Peak.

Beyond the personal challenge, the McDonald Forest 50K is celebrated for its vibrant community atmosphere and its impactful mission. Proceeds from this event support local high school cross-country/track and ski teams, the Corvallis Mountain Rescue Unit, and the OSU Research Forest. The race culminates in one of the Pacific Northwest's sweetest finishes: a pine needle-cushioned downhill trail leading to a lively post-race party with homemade vegan soup, bread, cookies, drinks, and a bluegrass band. This experience blends natural beauty with a deep sense of camaraderie, making "The Mac" an unforgettable journey for any trail runner.
