Oregon's Prettiest & Best Supported 100-Miler

Mountain Lakes 100 is one of the country’s most scenic 100-milers. Starting and finishing at Olallie Lake, and running along dozens of 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. Registration is not a lottery. This race is a Western States 100 qualifer. If you end up on the wait list, know that we have gone through the entire wait list by the beginning of September the last few years. Train like you'll get in and do your trail work.

Capacity: 150

Trail Work Requirement: All runners must complete 8 hours of trail work between October 1 of the previous year and September 1 of the race year. Those who do not submit their hours will forfeit their spot.
