Welcome to the Timberjack Ultramarathon and trail carnival. More details will come as we work through the permits and get everything set. Observant visitors to this site will notice the event date has changed; that was to provide more daylight for runners. We don't anticipate any more changes.

Experience the Trail Running Capital of North America! Ponderosa and lodgepole pines line the course as you roll along ancient volcanoes and the Deschutes River valley. Start and finish along the Cascade Lakes Scenic Byway in the shadow of the majestic Mount Bachelor.

A portion of the proceeds from this event will be donated to charity; both to local Bend efforts as well as to the National Parks Foundation.


The 100k course features 6500+ ft of elevation gain. The 30k features 2000+ ft of elevation gain over a single-loop course. Both courses start and finish at the Wanoga Sno Park and pass the Deschutes River valley. 

The course is a championship caliber, three-lap loop course in a contained, family-friendly package.

We also have a single-loop course mapped out for the future that's even tougher and more beautiful. Why have two courses? Eventually the lap course will be a backup in the event of inclement weather. But for now, we'll enjoy it as the main event. Which is good for you if you end up having to drop down mid-race.

CUTOFF for the 100k will be midnight (18 hours). There will be a mid-race cutoff at Wanoga at 24.7 and 43.5 miles based on projected finish pace (approx 17:00/mi pace) at 1:00pm and 6:20pm.
