Oregon's Prettiest & Best Supported 100-Miler
NOTE: Much of the early portion of the course, around the Olallie Lake area, was burned in 2020 fires. We won't know if we can use that section of the course, but are anticipating having to use the alternate course again in 2022. The race would start and finish at the Historic Clackamas Ranger Station instead of Olallie Lake. This is the location of the big crew aid station on the normal course and also where we put on the Mt. Hood 50 races.
Mountain Lakes 100 is of the country’s most scenic 100-milers. Starting and finishing at Olallie Lake, and running along more than 25 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. The aid stations and support on the course is outstanding. You'll be greeted by experienced volunteers who are as focused on getting you to the finish as can be.
This race is a Western States 100 and Ultra-Trail du Mont-Blanc® qualifer
