Bigfoot 100k Information

Join us on a 100k exploration of the Cascade Mountains

of Washington State

​Friday, August 10-11, 2018


Registration opens Jan. 1, 2018 at 9am PST. Register here


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. Just like last year, the race will start AND finish at Marble Mountain Sno Park. Please see the Runner's Manual for the most up to date information. ​
