Run For The Hills
18th annual Run for the Hills! Scenic 8k and 30k trail runs through Bald Hill, Fitton Green Natural Area, Greenbelt Land Trust, and Crestmont Land Trust in Corvallis, OR. Plus a 2-mile family-friendly run/walk on the paved path at Bald Hill, and a 1/4-mile run for kids! Great community atmosphere and an excellent first time trail race.
All proceeds go towards the Greenbelt Land Trust. This event has raised over $85,000, which has allowed for new trails to be built, some of which are now used in the race.
Registration required, and fees vary by race. Find more information here.
