Is REVEL Mt Charleston a Good BQ Course in 2027?

Published August 13, 2026 · Estimates, updated each registration cycle

Short answer: it is the fastest clock time most runners will ever see, and it now carries the largest adjustment Boston applies short of an outright ban. REVEL Mt Charleston starts at roughly 7,600 feet in the Spring Mountains north west of Las Vegas and finishes near 2,500 feet, a net drop of about 5,100 feet. That lands in the Boston Athletic Association's second tier, so from the 2027 race onward the time you submit gets ten minutes added to it. Your finish line clock does not change. Your application time does.

Ten minutes, and how close it came to being worse

The BAA's tiers run in three steps. A net drop of 1,500 to 2,999 feet adds 5:00. A drop of 3,000 to 5,999 feet adds 10:00. At 6,000 feet or more the course cannot be used for qualifying at all. Mt Charleston sits near 5,100 feet, which is the upper half of the middle tier and under the ban line, but not by a huge margin. The full mechanics are in the downhill rule explainer. Note that the tier depends on net drop, start elevation minus finish elevation, not on the total descent accumulated over the course.

Here is the practical cost. Our central estimate for the 2027 cutoff is about 5:15 under the standard, and that is an estimate rather than a BAA figure. To sit at that same estimated line off Mt Charleston you need a raw buffer of roughly 15:15, because ten minutes of it vanishes on submission. For a man aged 18 to 34 with a 2:55:00 standard, that is the difference between running 2:49:45 on a flat course and 2:39:45 here for the same odds. For a woman aged 18 to 34 the target lands near 3:09:45. Those are serious times, and they are the reason the downhill shortcut is much narrower than it looks.

What the course actually gives you

The descent is relentless and fairly consistent, averaging close to 200 feet of loss per mile, with the steepest grades early while you are still high in the canyon. The race starts before dawn in spring to beat the desert heat, and the thin air at the top is a real factor for the first few miles even though you are running downhill through it. The course is USATF certified and chip timed, so the time itself is unquestionably valid for Boston. It simply arrives with a ten minute tax attached.

The other cost is muscular rather than aerobic. Five thousand feet of sustained descent loads the quadriceps eccentrically for over two hours, and runners who have not done specific downhill training regularly report that their legs stop cooperating somewhere after mile eighteen while their breathing is still easy. Recovery afterwards is slower than from a flat marathon of the same duration, which matters if you were planning a backup qualifier a few weeks later.

Timing and entry

Mt Charleston is run in the spring and fills early, so entry is a matter of registering in time rather than winning a lottery. A spring race sits comfortably inside the qualifying window ahead of Registration Week, which for the 2027 race runs September 14 through 18, 2026 (see the registration dates). That leaves room in the calendar for a second attempt on a flat course if the adjusted time comes back thinner than you hoped.

Verdict

Run it for the experience, for a personal best on the clock, or if you are confident of clearing your standard by fifteen minutes or more. If your qualifier is going to be anywhere near the line, a flat certified course keeps every second you earn and is the better strategic choice. Compare the options first: see which marathons are too downhill, St. George at the five minute tier, and the best flat BQ marathons. Then run your goal time through the predictor to see the buffer it produces against thirteen years of real cutoffs, and subtract ten minutes from that buffer if the goal time is coming from Mt Charleston. The tool does not yet model the index for you.
