The race starts at the Hyak trailhead on the Palouse to Cascades Trail east of the Snoqualmie Pass. After half a mile, runners enter a pitch black tunnel for 2.4 miles.  So a light source or headlamp is highly recommended. Once you are about 50 yards into the tunnel, you can see a pinpoint of light which is the “Light at the End of the Tunnel” over 2 miles away.

Racers continue for 5 more miles through forested slopes to the Cedar Falls Trailhead at Rattlesnake Lake.  The course then continues on the Snoqualmie Valley Trail through a second-growth forest.  Finally, the finish is at a gravel parking lot along North Bend Way 2.4 miles SE of downtown North Bend.

The course has mainly packed gravel on an old railway. Many runners enjoy wearing trail shoes and running gaiters.
