⏵ Course guide · Central Oregon volcano race
Bachelor Ascent sends four separate races, a 50K, a 28K, a 16K, and a straight-up Vertical Ascent 5K, all the way to the 9,000 foot summit of Mt. Bachelor above Bend, Oregon. I will walk you through the climb and the four-distance format first, then give you a pacing and fueling plan built for volcanic alpine terrain and mountain weather. There are free calculators along the way to dial in your own numbers.
These facts come from the official Daybreak Racing event page. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
All four Bachelor Ascent races, from the 50K down to the Vertical Ascent 5K, climb to the 9,000 foot summit of Mt. Bachelor. There is no easy distance here, only a shorter or longer approach to the same climb.
The race is staged entirely at Mt. Bachelor's West Village area within the Deschutes National Forest. Expect rugged volcanic alpine terrain and real mountain hospitality, a celebration of the peak rather than a fast, groomed course.
Starts are staggered through the morning: 50K at 8:00 AM, 28K at 8:30 AM, 16K at 9:00 AM, and the Vertical Ascent 5K at 9:30 AM. Every distance climbs to the same 9,000 foot summit, so the shorter races are essentially a more direct route up the mountain rather than an easier objective.
Daybreak does not publish a total elevation gain number here, only that the course reaches 9,000 feet. Above mid-mountain elevations, conditions can turn harsh or change rapidly regardless of what the forecast looks like at the Bend trailhead, so treat the mountain, not the mileage, as the variable that decides your day.
With no published elevation gain figure, pace by effort and the cutoffs rather than a target vert-per-mile number that does not exist yet.
Every distance here ends at 9,000 feet, so the closer you get to the top, the thinner the air and the steeper the effort likely becomes. A grade-adjusted pace target keeps you from burning your legs on the lower slopes only to fade on the actual summit approach.
The 50K, 28K, and 16K all finish by 5:00 PM regardless of their staggered starts, giving you 9, 8.5, and 8 hours respectively. Check your pace against that shared finish time early, since a slow start on any of the three eats directly into your buffer at the same clock time as everyone else.

September in Central Oregon is usually mild at trailhead elevation, but a 9,000 foot summit finish adds real altitude exposure most runners are not training for day to day.
Aim for roughly 60 to 90 grams of carbohydrate per hour on the 50K and 28K, and sodium in the 300 to 700 mg per liter range. Appetite can suppress at altitude even when your effort stays high, so lean on easy-to-digest options as the course climbs toward the summit.
Conditions above mid-mountain elevation can change quickly regardless of what looks reasonable at the start. Carry more fluid and layers than a trailhead forecast implies, especially on the longer 50K and 28K where you spend more time exposed near the summit.

Daybreak Racing does not publish a total elevation gain figure for any Bachelor Ascent distance, but every race, down to the shortest Vertical Ascent 5K, climbs to the 9,000 foot summit of Mt. Bachelor. That single fact tells you most of what you need to know: even the shortest option here is a real climb, not a warm-up. Mountain weather above mid-mountain elevations can also change quickly, which adds a layer of difficulty a flat course profile would not.
Four options, all summiting Mt. Bachelor: a 50K, a 28K, a 16K, and a straight-up Vertical Ascent 5K for runners who just want the climb without the extra mileage. Each has its own start time and cutoff, staggered through the morning at Mt. Bachelor's West Village area.
A summit finish at 9,000 feet means real elevation exposure even if you live and train near sea level. Aim for roughly 60 to 90 grams of carbohydrate per hour on the 50K and 28K, and keep sodium in the 300 to 700 mg per liter range. Mountain conditions above mid-mountain elevation can be harsh or change rapidly, so carry more than you think you need rather than relying on a single aid stop. Build your numbers with the free ultra fueling calculator before race day.
The Vertical Ascent 5K has a 3 hour cutoff from its 9:30 AM start. The 50K, 28K, and 16K all share a 5:00 PM finish line cutoff, which works out to 9 hours for the 50K, 8.5 hours for the 28K, and 8 hours for the 16K given their staggered start times. None of these are especially tight for a well-prepared runner, but the summit climb and potential mountain weather mean you should not assume an easy day just because the cutoff feels generous.
The race takes place entirely on Mt. Bachelor's volcanic alpine terrain within the Deschutes National Forest, featuring rugged ground and genuine mountain hospitality at the West Village staging area. Because the course climbs to a 9,000 foot summit, weather above mid-mountain elevations can turn harsh or change quickly, so come prepared for conditions well outside what you would expect at the Bend trailhead.
The 16K and Vertical Ascent 5K are reasonable entry points if you want to experience the Mt. Bachelor summit climb without committing to ultra distance. The 50K and 28K ask more: a real volcanic alpine climb to 9,000 feet with mountain weather as a variable, so prior climbing experience at elevation is a genuine asset. If this would be your first ultra, the 28K is the more honest starting point than the 50K.
