One of the country’s most beautiful 100 mile races starts at Olallie Lake and runs along more than 25 mountain lakes. This race features the best trail running Oregon has to offer – technical and rocky sections, views of mountain peaks in every direction, and 60 miles of luscious sections of the Pacific Crest Trail.
This race is part of the Northwest Mountain Trail Series.

The top finishers will also win a free pair of shoes from Altra.
There are also many raffle prizes from our sponsors. All finishers will receive a cool buckle.
