Description
The Waldo 100K Ultramarathon is a challenging 100K loop-type course starting at Willamette Pass Ski Area (70 miles east of Eugene, Oregon) at elevation 5120', climbing up several mountains including Fuji, The Twins, and Maiden Peak before returning to the ski area. The route is mostly single-track trails with some fairly remote sections and has many incredible views of pristine Waldo Lake. It is not a beginner-level ultra and we recommend coming into the race with experience.

Trail to Zero™
We are pleased to be one of the first races to participate in Ultrasignup's Trail to Zero™ program. A recent statistic from 29 mass participation events in North America between 2014 and 2019 indicates that 98.5% of an event's carbon footprint came from event-related travel by participants. When you register for the lottery you will have the option to contribute one dollar (or more) to the Trail to Zero™ carbon offset program to help account for your travel and support an impactful climate-action project.
