Tunnel Marathons

Celebrating 10 Years Running

Welcome to Tunnel Marathons! To our participants in the past years of Light at the End of the Tunnel Marathon and especially to our volunteers, we want to extend a big Thank You! We are gonna do it big this year with 3 races, all on the same fast Boston-qualifying course.

This is a unique course you WON'T find anywhere else. Set in the beautiful North Bend and Snoqualmie area, it features a jaw-dropping 2-mile tunnel cut right through rigid landscape eventually opening to a sprawling Pacific Northwest paradise.


We offer 3 races on the same fast, Boston Qualifier course.
Each race now has a runner limit of 800, with entries costing $95.

The June 11th race has sold out!

Registered volunteers who help out with the race earn a reserved place in our other marathon! Find out how to volunteer and get the right to register for a sold out race!
