​​Bigfoot 100k Information

July 22-23, 2017

Join us on a 100k exploration of the Cascade Mountains of Washington

Welcome to the Bigfoot 100k!

Registration opens Jan. 1, 2017 at 9am PST. Register here


Day of race registration will be available! Plan to register either Friday, July 21 from 3pm to 7pm or Saturday morning from 5:45am-6:45am. Please bring cash or check as we will not be able to process cards on site.


The Bigfoot 100k begins at Marble Mountain Sno Park and runs around Mt. St. Helens and into the Mount Margaret Backcountry. The course showcases some of the most stunning views of the area including the desolation zone of Mt. St. Helens, hanging lakes, lava fields, long mountaintop ridge lines with stunning forest, mountain and lake views. You might even see a Bigfoot or two… it’s been known to happen in these parts.

The race has 5 aid stations (including the finish line), averaging approximately 13.6 miles between stations. Runners will be timed from
the start to the moment they cross the finish line. The race will be well marked and the aid stations well stocked, but it does require a certain amount of self sufficiency with one leg being 18.5 miles long. There are plenty of streams to get water from and trail runners will enjoy the solitude and beauty of a race course that is truly unique, non-repetitive and wild. Please note that the 2017 course has been modified due to road closure of Road 99. The race will now start AND finish at Marble Mountain Sno Park. Please see the Runner's Manual for the most up to date information. ​

ENTRY REQUIREMENTS: No entry requirements. We recommend that runners consider that this is a tough
100k race that requires runners to be fairly self sufficient and prepared for the weather. Aid stations average 13.6 miles apart. We will have fun and well stocked aid stations. One aid station will be minimal - it's an 8 mile hike in (see Runner's Manual). We take food seriously and will offer a large variety of options at the full aid stations.
