The Beacon Rock races are harder than your average trail race courses thanks mostly to the elevation gain and loss for each course, 7500ft for the 50k and 3750ft for the 25k. The route is basically a ~23km “figure eight” with a 0.8 mile out and back from the start/finish area, The Beacon Rock Group Camp Site, to the figure eight. The 50k is two “loops” of the 25k course.
Each loop has a mixture of pavement(0.6mi), single track trail, and wider double track or dirt road. Most of the time the tread is smooth, the grade gradual and you can trust your footing but of course there are exceptions! You’re in the forest most of the time but the views(on a clear day) going up and from the top of Hamilton Mountain of the Columbia River Gorge, Mt Hood, and Mt Adams are spectacular.
