Mountain Lakes 100

Olallie Lake, OR
How's that for a finish shot?

One of the country’s most beautiful 100 mile races starts and finishes at Olallie Lake. 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. You run past more than two dozen mountain lakes and are surrounded by shocking oranges, reds, and yellows with all the Fall foliage.

You'll be treated like never before at the aid stations. The volunteers are committed to getting you to the finish line. 

There is a pasta feed the night before the race and breakfast is served Sunday morning.
