Tunnel Marathons: Tunnel Light

September 21, 2025 @ 7:00 am - 12:00 pm PDT

|Recurring Event (See all)

An event every year that begins at 7:00 am on day third of September, repeating until September 21, 2025

  • « Appletree Marathon | Half Marathon | Sunset 5K
  • Seattle Running Club Sunday Trail Run »

The Tunnel Marathon races offer one of the fastest courses in the country. This point to point course delivers excellent times thanks to the consistent downhill grade and low starting elevation. It is the perfect race to set a Personal Record and snag a Boston Qualification on a single course.

Run through a dark tunnel lit by your best running mates, gawk at the mountains and waterfalls, take in the sweet Washington air and let your legs go. The speed of the course comes from a loss of just over 2,000′ of elevation at a consistent grade.

The Tunnel course is in the top 10 for a Boston Qualifier per Runners World and Race Raves! This USATF Boston Certified course (WA 08031 MW) has helped over 30% of our runners snag a Boston Qualifier on the ORIGINAL Tunnel course. Founded by Washington residents and offered since 2007, you can be sure you’re in good hands. It’s been a favorite among racers and why runners continue to come back for more!
