One of the country’s most beautiful 100-mile races starts at Olallie Lake and runs past more than 25 mountain lakes between Mt. Jefferson and Mt. Hood. 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 2019 race is a lottery. You can enter the lottery between February 1-7, 2019. We will draw 170 names on Feb 8th. Those not selected in the lottery are put on the wait list. Registration for the wait list reopens on February 9th.
Optional shirt is available for purchase during registration. Shirts are available until August 25.
Please note that there are no transfers to other runners. If you need to cancel your registration and it’s more than 30 days prior to the race, you will receive a 50% credit toward a future Go Beyond Racing race. If your cancellation is 30 days or less from race day, there is no credit, no refund, or no transfer. See our cancellation policy for details.
As trail runners, we benefit from the work of those who built and maintain the trails where we run. Many of the organizations and groups who do this work have little and shrinking budgets and rely heavily on volunteers. We strongly believe that all of us should give back by volunteering to do trail work on a regular basis.
For the 2019 Mountain Lakes 100 race, all racers must complete a total of eight (8) hours of trail work. The trail work doesn’t need to be done before registering; just sometime after January 1, 2019 and before September 1, 2019. The required form is signed by the trail work site manager and emailed before the deadline. Entrants without the required trail work will forfeit their spot on September 2nd and someone from the wait list is invited to take their place. We define trail work as maintenance of existing trails and development of new. The trails can be anywhere in the world. More details on the requirement are in this post.
The top three male and female finishers will receive prizes from our sponsors. There are also many raffle prizes. All finishers will receive a belt buckle and a finisher pint glass. Those who finish under 24-hours earn a special buckle.
The all-you-can-eat breakfast (mmm, bacon) is free for all volunteers, racers and up to three of their crew. Families and friends can purchase a meal for $5. We hope everyone stays and enjoys the fun!
The weather in the northwest in September is usually fairly stable with cool, clear days. The temperatures can drop to the 30s during the nighttime. However, as with any mountain race, the weather can be unpredictable so pack accordingly and check the weather before you leave.
Detroit Lake is one hour of the start and has several lodging options, including:
Government Camp is about 1.75 hours from the start and has lodging also.
Wonderland Expeditions rents fully-outfitted 4x4s and SUVs with popup campers and rooftop tents.
Double check these directions to what Google Maps gives you. Google Maps may tell you to turn onto Forest Road #4220 from Hwy 46. Do not take this as it is a much slower and bumpier option for high-clearance vehicles. The below are the best routes.
From Portland The best route from Portland is through Estacada on Highway 224. From I-205/224 (Clackamas), take Hwy 224 east for approximately 43 miles. Continue on Highway 46 for approximately 21 miles to Forest Service Road 4690. Turn left and continue for approximately 8 miles to Forest Service Road 4220. Turn right and drive approximately 5 miles to Olallie Lake Resort. The road is paved until the last 10 miles, where the road turns to gravel and is slow-going and rough in spots. Passenger cars can certainly make this, but high clearance vehicles like trucks and SUVs are better.
From Salem The best route from the Salem area is through Detroit to Forest Highway 46. Turn left just as you pass over the bridge into Detroit. Follow Highway 46 for approximately 21 miles to Forest Service Road 4690. Turn right and continue for approximately 8 miles to Forest Service Road 4220. Turn right and drive approximately 5 miles to Olallie Lake Resort.The road is paved until the last 10 miles, where the road turns to gravel and is slow-going and rough in spots. Passenger cars can certainly make this, but high clearance vehicles like trucks and SUVs are better. It is about an hour drive from Detroit to the start. NOTE: Map programs will not display this route during the winter as the road is closed while it is snowed in.
Parking at Olallie Lake Resort is tight and we need to be considerate of other visitors and forest users. There are three places to park:
We HIGHLY ENCOURAGE CARPOOLING!
If you are interested in carpooling, you can post here to find or give a ride. This is a Google spreadsheet that is viewable to anyone with the link, so only post what you want public. Carpooling earns you a Carpool Coaster too!
We love volunteers and our racers do too! To make this race a success we need almost 100 people to help at bib pickups, race start and finish, aid stations, and on the trail. You can sign up for the assignment you’d like on Ultrasignup. Click on the green Volunteer button.
This race is called Mountain Lakes 100 because… it is in the mountains. It is remote. There is no internet or cell service. There are no stores or gas stations nearby. Many of the roads are not paved and some are rough. There are no showers. Please come prepared with this in mind. In fact, consider this a nice weekend away from the city in all senses. The start/finish is at 5,000 feet elevation and the high point on the course is at 5,700 feet.
We do have a few rules that apply to all Go Beyond Racing races. Be sure you are familiar with them.
