Mountain Lakes 100 : Oregon trail 100 miles
Mountain Lakes 100 is a 100 miles trail race held near Olallie Lake Resort on National Forest land. The course follows large sections of the Pacific Crest Trail between Mt Jefferson and Mt Hood, with rocky and technical single-track, numerous lakes, and mountain-peak views. The course total includes about 11,700 feet of elevation gain and loss; the route ranges from roughly 3,300 feet to 5,700 feet in elevation.
The event is limited to 150 entrants. Registration fees vary by date: $355 (Jan 1–14), $370 (Jan 15–Mar 14), and $390 (Mar 15–Aug 31). There are no transfers to other runners and no refunds; cancellations more than 30 days before the race receive a 50% credit toward a future race, and cancellations 30 days or less before the race receive no credit.
Trail work requirement: all entrants and waitlisters must complete eight hours of trail maintenance sometime after October 1 and by September 1; failure to submit the required form by the deadline results in forfeiture of the race spot.
On-course support is provided at aid stations and by HAM radio; there is very limited internet and cell service along the course so live tracking is not available aside from finish-line results. Awards include prizes for top finishers, age-group and non-binary awards, raffle prizes, and finisher items such as a belt buckle and a pint glass. The race occurs on multi-use trails where horses may be encountered. Visit the organization's website for the most recent information.
