The weather in the northwest in September is usually fairly stable with cool, clear days. The temperatures can drop to the 30’s during the nighttime. However, as with any mountain race, the weather can be unpredictable so pack accordingly and check the weather before you leave.
There are multiple campgrounds near the start/finish – Olallie Meadows, Lower Lake, Camp Ten, Paul Dennis and Peninsula. Click here for campground details and here for a map. In addition, the following hotels are located within one hour of the start.
Double check these direction 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 west 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, but suitable for all vehicles.
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, but suitable for all vehicles. 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 love volunteers and our racers do to! 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 with the heart.
