Locals know it as their daily escape, and visitors will be floored that such a vast wilderness lives right inside city limits.
This is Portland’s only 50K, and it’s paired with a hilly, green-saturated half marathon that will test your legs and lift your spirit. With every climb and descent, you’ll feel part of the trail community that makes these races unforgettable.
