The course
A classic mountain ultra
Technical terrain and variable weather. The lollipop course starts and finishes with 10k on the Interurban Trail — smooth running out and back.
The middle 30k is what this race is known for: you climb (5,000 ft), traverse and descend the famous Chuckanut Mountain ridge, exposed to the elements and the beautiful Pacific Northwest terrain.
