The Tunnel Marathon & Half Marathon is engineered for speed — an ideal opportunity to set a Personal Record, earn a Boston Qualification (marathon), or run your first race. From the moment you enter the historic Snoqualmie Tunnel to the final miles surrounded by mountain views, waterfalls, and crisp Washington air, the Tunnel Marathons are as breathtaking as they are fast.

2026 Course Update: Due to severe storm damage, the 2026 event will follow an alternate, fully permitted route. The 2026 course will remain fast and scenic, featuring approximately 1,000 feet of net elevation drop (marathon & Half). Both races will be USATF-certified, and the marathon is a Boston Qualifier.

Built for Speed:

• Approximately 1,000 feet of net downhill
• Smooth, packed gravel surface (road or light trail shoes work well)

Registration Includes:

• Professional chip timing
• Custom race bib
• Finisher’s shirt and medal
• Post-race food and festivities
• Shuttle transportation back to Hyak Sno-Park

Shuttle & Finish: After finishing at Garcia Trailhead, runners will enjoy a scenic one-mile walk down Forest Service Road 9020 to the shuttle buses. Shuttles return participants to Hyak for celebration and refreshments.
