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.
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.
Trail Work Requirement
There is a trail work requirement for this race. All runners must complete 8 hours of trail work between October 1 of the previous year and September 1 of the race year. This is a real requirement and those who do not submit their hours will forfeit their spot. Details are on the race website. For those on the wait list, this requirement applies to you too, so don't wait until the last minute.
We feel this requirement is very important and hope that many runners will learn the value of volunteering to maintain trails, and just how much fun it is, as a result. Because of this race, there is over 1,200 hours of trail work completed around the country.
