Tunnel Vision Marathon & Half Marathon
The event offers a Marathon and a Half Marathon on a point-to-point course between Snoqualmie Pass and North Bend, Washington.
Distances:
- Marathon
- Half Marathon
Course details
The marathon is point-to-point and drops just over 2,000 feet from start to finish, with an average downhill grade of about 2.2%. The marathon course passes through the Snoqualmie Tunnel. The half marathon covers the second half of the full course, begins at the midpoint of the marathon, and finishes at the same finish line in North Bend. The half does not pass through the tunnel.
Both courses run on trails that are former railroad grades: the Palouse to Cascade Trail and the Snoqualmie Valley Trail. Trail surface is packed gravel; both trail and road shoes are appropriate. The marathon course is USATF Boston certified (WA21010RMB). The half marathon course is also USATF certified. The organizer reports that the marathon course has produced Boston-qualifying performances for a substantial share of finishers on the original course.
