2026 Race Dates (registration will open on February 1, 2026) June 7th, August 9th, and September 13th, 2026

Dear Runners, Many of you may be aware that Washington State has recently experienced several major storms that have caused widespread and devastating damage across the region. Our hearts go out to all those who have been affected. We were recently informed that due to severe storm damage to multiple sections of our race course, we will not be permitted to use the original course for the 2026 Tunnel Marathons. This was not an easy update to receive or to share, as we know how meaningful this course is to so many of you. Please know that we are actively working with our permitting agencies to develop an alternative route for the Light at the End of the Tunnel Marathon & Half Marathon, Tunnel Vision Marathon & Half Marathon, and Tunnel Light Marathon & Half Marathon. Our goal is to continue offering you a safe, scenic, and memorable race experience. Registration will be temporarily paused while we finalize details with the appropriate agencies. We are hopeful to have an approved alternate course and registration ready to open on February 1, 2026. We truly appreciate your patience, understanding, and continued support as we diligently work through these unforeseen challenges. Your trust means everything to us, and we remain committed to supporting your running journeys every step of the way. Please stay tuned for further updates. We look forward to sharing more details soon and to welcoming you back for another incredible Tunnel Marathon experience. With gratitude, Kristal Sager Race Director, Tunnel Marathon Team
