⏵ Course guide · ~5,000 ft down into the valley
REVEL Mt Charleston descends roughly 5,000 feet from the mountain into the Las Vegas valley, sharing the same fast, quad-testing profile as its sister race, REVEL Big Bear. I will walk you through the course and the likely Boston downhill BQ penalty first, then give you a pacing plan built for sustained descent, plus free tools to dial in your own numbers.
⏵ Boston 2027 downhill BQ penalty (likely applies)
Starting with the 2027 Boston qualifying cycle, the BAA adds a time penalty to marathon times run on courses with large net downhill, 10 minutes for the 3,000 to 5,999 foot bucket. Mt Charleston's roughly 5,000 foot drop shares that same profile with sister race REVEL Big Bear, so this penalty very likely applies here too. Confirm the exact current bucket with the BAA before counting on a specific submitted time for a BQ attempt.

The route drops roughly 5,000 feet from Mt Charleston into the northwest Las Vegas valley, a profile similar to REVEL's other marquee downhill course, Big Bear.
Like Big Bear, this course is a real net downhill built for fast times and BQ attempts, and that same downhill grade is a serious eccentric load on your quads over 26.2 miles. Runners who train specifically for descending arrive with legs intact for the final miles; runners who do not often find the grade that was helping their pace turns into the thing that slows them down late.
The course moves from the cooler elevation of Mt Charleston down into the warmer Las Vegas valley floor, so expect meaningfully different conditions at the start versus the finish, similar to other mountain-to-valley downhill courses.
Treat the grade as something to manage, not free speed. The same discipline that works for REVEL Big Bear applies here.
Downhill-specific training in the months before the race builds the eccentric quad strength this course demands. On race day, a grade-adjusted pace target keeps your effort honest so you are not simply following gravity to a pace your legs cannot hold for the full distance.
REVEL provides official pacers across goal times, a real asset on a course where the temptation to go out too fast is constant simply because the road tilts downhill. Running with a pacer targeting your goal removes that guesswork.

⏵ Train for it with Summit Line

Very likely, though we cannot confirm the exact minute adjustment or bucket boundary for this specific course. Starting with the 2027 Boston qualifying cycle, the BAA adds a time penalty (10 minutes for courses with 3,000 to 5,999 feet of net downhill) to marathon times run on steep-drop courses, a rule aimed at races like REVEL Big Bear. Mt Charleston shares a similar large net-downhill profile with Big Bear, roughly 5,000 feet of descent, so it sits in the same general category of course this rule targets. Confirm the current BAA course-index bucket directly before you count on a Mt Charleston finish time for a Boston qualifying attempt.
Like its sister race REVEL Big Bear, Mt Charleston descends roughly 5,000 feet from the mountain to the Las Vegas valley floor, a course built for fast times and BQ attempts. That much sustained downhill running is a real eccentric load on your quads regardless of how fit you are on flat ground: runners who show up without downhill-specific training often find their legs give out in the final miles even though the course is helping their pace the entire way.
Train the descent specifically before race day, repeated downhill running in the months beforehand builds the eccentric quad strength this course demands. On race day, run the early downhill miles at a controlled effort rather than letting the grade pull you to a pace you cannot sustain for 26.2 miles; REVEL provides official pacers, and running with one targeting your goal time is a strong way to avoid going out too fast simply because gravity makes it easy.
Both the marathon and half marathon start at 6:00 AM. The course time limit is based on a 15:00 per mile pace, working out to 6 hours 33 minutes, with the finish line closing at 12:33 PM. That is a generous window relative to the distance given how much of the course runs downhill.
Registration is open, with no lottery and no qualifying time required. That makes it an accessible race to sign up for, though most runners choose it specifically to chase a fast time or a Boston Qualifier on the steep downhill profile.
Expect a high-desert temperature swing: a cool start at the Mt Charleston elevation, warming as the course descends toward the Las Vegas valley floor. Dress in removable layers for the cooler mountain start and plan for meaningfully warmer conditions by the finish.
