Carkeek 12 Hour

The Carkeek 12 Hour event is back in Seattle on October 19, 2024. This event is known for its challenging course with lots of gain and unpredictable fall weather. Whether you're running for 12 hours or 6 hours, take it one step at a time and enjoy the 1.93-mile loop.

Costumes are encouraged and rewarded at this fun event, especially with Halloween around the corner. Bring out your best Halloween costumes and join in the festive spirit. Prizes will be awarded for the best costumes, including for pets in costumes!

Not only is this event a blast, but it's also a fundraiser for trails. All registration fees and donations go towards supporting trail work, education, and advocacy in the Northwest region. Your support helps maintain and improve local trails for everyone to enjoy.
