Deception Pass Trail Races

Deception Pass Trail Races run over two days near Oak Harbor, Washington, on December 12 and 13, 2026. The 50K (about 31 miles) goes first, on Saturday, and the 25K (about 15.5 miles) follows on Sunday. Both courses head through dense forest, run alongside lakes and ponds, and cross several bridges. Canicross is allowed, so you can race with your dog.

This is trail running in the Pacific Northwest in December, and time on feet counts for far more here than pace per mile: build toward back-to-back weekend runs on trails, and practice eating and drinking on the move if the 50K is your target. The 25K works well as a first long trail race, or as a step up for a road runner who wants to see what an ultra-length day would ask.
