Tunnel Vision Marathon

Tunnel Vision Marathon & Half Marathon

• Marathon
• Half Marathon

The Tunnel Vision events are point to point races on trails near Snoqualmie Pass and North Bend, Washington. The marathon route begins at Snoqualmie Pass, passes through the Snoqualmie Tunnel, and finishes in North Bend. The marathon course follows the Palouse to Cascade Trail and includes a net loss of just over 2,000 feet at an approximate consistent grade of 2.2 percent. The organizer describes the low starting elevation and steady downhill grade as factors that produce fast times. The marathon is USATF Boston certified under course code WA21010RMB; the organizer reports a high Boston Qualifier rate on the original Tunnel course and mentions placement in top 10 lists for BQ potential.

The Tunnel Vision Half Marathon starts at the halfway point of the full marathon and finishes at the same finish line. The half offers a net drop of about 1,100 feet and follows packed gravel trail surfaces that are former railroad corridors on the Palouse to Cascade and Snoqualmie Valley trails. The half course is USATF certified. For 2026 the organizer has paused registration while working with permitting agencies because storm damage has affected sections of the Palouse to Cascade Trail; an alternate course and the timing for permit approval are under discussion with state parks.
