Experience the magic of a 29-year trail running tradition through the majestic, moss-draped forests of the Oregon Coast Range at the Mac Forest Trail Run, March 14, 2026. This beloved event, now supporting the Corvallis Trail Series, offers a challenging 15k and an accessible 5k on a classic mix of singletrack trails and logging roads in OSU's McDonald Forest. With 1,450 feet of climbing, the 15k course rewards runners with potential views of the Cascades and the promise of quintessential Pacific Northwest mud.
Proceeds from the cupless race benefit the Oregon Running Foundation, providing vital support to local high school cross-country teams and getting shoes on young runners' feet. With discounted youth entry fees, the event is a fantastic family outing. Register early to secure your commemorative shirt and a spot in this storied spring race that beautifully blends community spirit with the raw beauty of the Willamette Valley's backcountry.
