⏵ Course guide · Central Oregon high desert ultra
Run The Rock sends its 50K, 25K, and Half Marathon fields through Smith Rock State Park and the Crooked River National Grasslands near Terrebonne, Oregon, with 5,500 feet of climbing on the 50K and Cascade views stretching from Mt Hood to Mt Bachelor. I will walk you through the terrain and elevation first, then give you a pacing and fueling plan built for exposed high desert climbing. There are free calculators along the way to dial in your own numbers.
These facts come from the official Alpine Running event page and its linked UltraSignup listing. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
Every distance runs through Smith Rock State Park and out into the Crooked River National Grasslands, high desert terrain that trades tree cover for wide-open views. The 50K climbs 5,500 feet and descends the same, the 25K climbs 3,300 feet, and the Half Marathon packs 2,500 feet into 13.1 miles.
The 50K runs 85% single-track with the rest on double track and dirt roads, while the Half Marathon is 90% single-track. Expect the classic Smith Rock combination: technical, rocky footing under the park's famous cliff faces, opening into rolling, exposed grassland stretches in the Crooked River National Grasslands. There is little shade anywhere on this course, so plan your sun protection accordingly.
Run The Rock spreads across two days, the 50K and 25K on Saturday, November 7, and the Half Marathon on Sunday, November 8. That structure makes it easy to run one distance and cheer for a friend racing the other, or to treat the weekend as a mini training camp in genuinely scenic high desert terrain.
The reward for all that climbing is a Cascade Range skyline that stretches from Mt Hood in the north to Mt Bachelor in the south, along with close-up views of Smith Rock's iconic sheer faces, a favorite of rock climbers as well as trail runners. Look up when you get the chance. The terrain earns your attention on the way, but the views are why people keep coming back.
With 5,500 feet of gain and loss packed into the 50K, and no published cutoff to chase, the smart approach is pacing the climbs honestly rather than racing an unknown clock.
A grade-adjusted pace target matters here because the terrain is not simple runnable trail, it is rocky Smith Rock single-track mixed with grassland climbs. Use it to set an honest effort for the ascents so you are not blowing up your legs on the way to the views, especially on the 50K where you climb and descend 5,500 feet over the full distance.
Without a stated cutoff time, build a vert-aware finish prediction using the real elevation numbers, 5,500 feet for the 50K, 3,300 for the 25K, or 2,500 for the Half, so you know what a realistic day looks like before you start rather than guessing on course.
⏵ Free tools to pace this course
Central Oregon's high desert in early November brings cool, dry air and real sun and wind exposure on the open grasslands sections, so plan your fueling and hydration around that climate.
Aim for roughly 60 to 90 grams of carbohydrate per hour. With 5,500 feet of climbing on the 50K likely stretching your time on course well past a flat-ground 50K, plan for a longer day than the mileage alone suggests, and pack enough fuel to cover that extra time.
High desert air is dry, which can mask how much you are actually sweating. Keep sodium in the 300 to 700 mg per liter range and drink on a schedule rather than waiting for thirst, since dry conditions make dehydration easy to underestimate. Sun and wind protection matter as much as fluid here, given how little shade the course offers.

It is a genuinely mountainous 50K by high-desert standards: 5,500 feet of gain and the same in loss, spread across mostly single-track (85%) through Smith Rock State Park and the Crooked River National Grasslands. That works out to roughly 350 feet of vertical change per mile, on rocky, exposed high desert terrain with big views but not much shade. The payoff is the scenery, the iconic rock faces of Smith Rock and a Cascade skyline stretching from Mt Hood to Mt Bachelor, but the climbing is real.
The 50K carries 5,500 feet of elevation gain and 5,500 feet of loss, according to the official course description. The 25K is a shorter, still-substantial 3,300 feet of gain, and the Half Marathon packs 2,500 feet of climbing into just 13.1 miles, a demanding ratio for a half. All three distances draw on the same rugged Smith Rock and Crooked River Grasslands terrain, they just cover different amounts of it.
Early November in Central Oregon's high desert usually means cool mornings, mild afternoons, and low humidity, but temperature swings through the day can be significant and wind is common in the open grasslands sections. Aim for roughly 60 to 90 grams of carbohydrate per hour and sodium in the 300 to 700 mg per liter range, leaning toward the higher end if the day runs warm and dry. Build your numbers with the free ultra fueling calculator before race day, since the specific aid station layout is not published here.
Alpine Running does not publish specific cutoff times for the 50K, 25K, or Half Marathon in the current race-day details. Given the 5,500 feet of gain on the 50K, budget real time for the climbing rather than assuming a flat-course pace, and confirm the current cutoff sheet with the race before you commit to a distance.
Expect classic Central Oregon high desert: rocky, exposed single-track through Smith Rock State Park's famous rock faces, opening into rolling grassland terrain in the Crooked River National Grasslands. The 50K is 85% single-track with the rest on double track and dirt roads, while the Half Marathon runs 90% single-track. Views stretch across the Cascade Range from Mt Hood in the north to Mt Bachelor in the south, but there is little tree cover, so sun and wind exposure are real factors.
The 25K, at 3,300 feet of gain, is a reasonable stretch goal if you have some hill training under your belt, and the Half Marathon is an approachable way to sample this terrain at a shorter distance, even with its own 2,500 feet of climbing. The 50K, with 5,500 feet of gain and loss on exposed high desert single-track, is a solid step up that rewards runners who have already handled real vertical terrain. Whichever distance you choose, train on hills and prepare for sun and wind exposure, not shaded forest cover.
