Description:
One of the country’s most beautiful 100 mile races starts at Olallie Lake and runs by dozens of mountain lakes and between two or Oregon’s cascade peaks. This race features the best trail running the Pacific Northwest 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 is a very runnable course and makes for a perfect first hundred. It’s also one of the best supported hundreds, with amazing aid stations and volunteers 100% invested in your finish.
