Mountain Lakes 100

Mountain Lakes 100

Mountain Lakes 100 is a 100 mile trail race that starts and finishes at Olallie Lake in Oregon and runs along dozens of mountain lakes. The course includes roughly 60 miles on the Pacific Crest Trail and features technical, rocky sections and views of mountain peaks in multiple directions. Aid stations and volunteer support are provided along the route.

Registration for the event is not lottery based and the field capacity is 150. Registration closes on Mon, Aug 31 at 11:59 PM PT.

All entrants must complete a trail work requirement of eight hours between October 1 of the previous year and September 1 of the race year. Runners who do not submit required hours will forfeit their spot. The trail work requirement applies to runners on the wait list as well; organizers have historically moved through the wait list by early September in recent years.

The cancellation policy gives a 50 percent credit toward a future Go Beyond Racing event when a cancellation is made more than 30 days before the race; that credit is valid for 365 days and is not transferable. Cancellations 30 days or less from race day do not receive credit, refund, or transfer.

The event is produced by Go Beyond Racing, an organizer of over three dozen trail races per year; the organizer lists safety measures, donations to beneficiaries, staffed aid stations, volunteer support, and efforts to reduce environmental impact among its race practices.
